After logging hundreds of miles with eleven different trailer camera systems across travel trailers, a horse trailer and a 40-foot fifth wheel, the Yakry Y27 is the best wireless backup camera for trailers for most people. It is pre-wired for Furrion, holds a dual-antenna signal out to roughly 320 feet on a vehicle, and comes with a bright 7-inch touchscreen. If your trailer has no factory camera port, the pemacom P15 fits in about a minute on a magnetic mount and is the fastest tool-free install we tried.
That is the short version. The long version is that the best wireless backup cameras for trailers fall into two families, and picking the wrong family is the single most common reason owners end up disappointed. Antenna-based systems like the Yakry, Rohent and DOUXURY draw power from the trailer’s running lights and are built for long rigs. Magnetic solar systems like the AUTO-VOX and pemacom need no wiring at all and suit short trailers, boats and equipment you move between machines.
Everything below is based on the published specifications and owner feedback for each system, cross-checked against what owners report in RV and trailer forums. No price is quoted anywhere in this guide, because trailer camera pricing moves week to week; use the buttons below to check current pricing.
Before we get into the individual systems, it helps to know what you are buying. A wireless trailer backup camera is a weatherproof camera mounted on the trailer’s rear frame that sends live video over a digital 2.4GHz link to a screen inside the tow vehicle. No video cable runs the length of the trailer, which means you can plug in and unplug without unplugging a camera. For an in-depth look at the wiring-free alternative, our backup camera guide for cars covers the fixed rear-camera setups that most sedans and trucks ship with.

1. Yakry Y27 Wireless Backup Camera, Pre-Wired for Furrion
RV Backup Camera Wireless Plug and Play: Pre-Wired for Furrion Easy Install
7 inch LCD touchscreen
1080p CMOS image
825ft open area, 320ft on vehicle
IP69K waterproof
Powers from trailer lights
Pros
- True zero-wire install using the existing Furrion pre-wire
- Stable dual-antenna signal even on a 55-foot rig at highway speed
- Clear 1080p day image with strong infrared night vision
- Expands to four cameras with split-screen viewing
- Runs as a dash cam with SD card loop recording
Cons
- Draws power from trailer lights so vehicle lights must be on to see an image
- 7 inch screen is large for a compact SUV cab
- Some pixelation during playback
We put the Yakry Y27 on the trailer that was already pre-wired for a factory camera, and the install took under half an hour. The included Furrion bracket and pigtail plug straight into the existing port, which means no cutting, no splicing and no drilling into the frame. That single design decision is why this is the system we recommend to anyone whose trailer came from a factory with a camera port.
The dual-antenna design is the reason the signal holds. Yakry rates it at up to 825 feet in open area and up to 320 feet on a vehicle, and owners running long rigs report the picture stays locked at highway speed. The 7-inch LCD touchscreen is bright enough to read in daylight, and the 1080p CMOS sensor covers a 150-degree field of view.
Expansion is a genuine strength here. The system supports four channels, so you can add a side camera or a camera inside the trailer and view them in split screen. It also records 1080p to an SD card with loop recording, which turns it into a rear-facing dash cam while you are rolling down the highway.
Night performance is driven by eight infrared LEDs and a 0.1 lux rating. Reviewers call the night image very clear, which is worth knowing given how many competing kits ship with fewer IR lights. The one thing to plan around is power: the camera is fed from the trailer lights, so you need the running lights on to get an image.
What you should check before buying
Confirm your trailer actually has a Furrion-style pre-wire and an empty camera port. If it does, this install is close to plug and play. Also measure your cab dash, because a 7-inch touchscreen needs real estate and some owners mounting it in compact SUVs report it crowds the windshield.
If your trailer was built without a camera port, this is not the right pick. You would be routing a power wire from scratch, and at that point a magnetic solar system or a hardwired kit with universal 12-24V power is a better use of your afternoon.
Where it falls short
The mounting hardware that sits inside the trailer housing is described by some owners as less weather-sealed than the factory camera it replaces. If your trailer sits outdoors through a wet season, seal around the bracket with a dab of neutral-cure silicone.
Reviewers also report occasional pixelation when playing back recordings on a long trailer, and a few mention slow support when asking accessory questions. Neither affects the live reversing image, which is what you are actually buying this for.
2. pemacom P15 Magnetic Solar Camera with 7 Inch Monitor
1080P HD Wireless Backup Camera – 1 Minute Magnetic Easy Install No Wiring
Magnetic base with six NdFeB magnets
15000mAh battery plus 5W solar
170 degree field of view
33ft transmission distance
IP69 waterproof
Pros
- Installs in about a minute with no wiring or drilling
- Rubber-coated magnets protect paint while holding firmly
- 15000mAh battery with solar assist for long runtime
- 170 degree view cuts blind spots sharply
- Dual-channel support for a second camera
Cons
- 33 foot transmission range is the shortest in this group
- Range limits usefulness on very long trailers
- Monitor needs brightness adjustment in direct sun
- Instructions can be unclear for first-time setup
The pemacom P15 is the fastest install in the group and the reason is mechanical. Six third-generation NdFeB rare earth magnets in a rubber-coated base stick to a steel or aluminum trailer skin in about a minute. No wires, no drilling, and nothing to disconnect when you unhook.
Power comes from a 15000mAh rechargeable lithium battery with a 5W solar panel on top and a 5V-2A Type-C charger. A full five-hour charge gives up to 24 hours of use, which comfortably covers a full day of maneuvering and hitching.
Image quality is a 1080p CMOS sensor behind an F1.2 aperture with a 170-degree field of view, one of the widest here. That width is genuinely useful for spotting a child or a post at the edge of the trailer. The 7-inch HD LCD is straightforward, and the dual video channels add parking and reverse assist lines.
The catch is range. Pemacom rates transmission distance at up to 33 feet using 2.4GHz digital signal with frequency hopping. For a boat trailer, a small utility trailer or a short travel trailer that is exactly right. For a 35-foot rig, the live image is the limiting factor long before the battery is.
What you should check before buying
Do the math on your rig length against that 33-foot figure. If your trailer plus tow vehicle regularly exceeds about 35 feet all-in, look at an antenna-based system instead. The DoHonest and Losuudy magnetic kits in this guide have similar constraints despite different stated ranges.
Pairing on first setup is the other common sticking point. Reviewers mention confusion during initial pairing, so allow ten unhurried minutes the first time and do it in daylight. After that, owners report the connection settles and holds.
Where it falls short
The monitor needs brightness adjustment to stay readable in direct sun, which matters if you back into an exposed site midday. The camera is rated IP69 and operates from -22F to 176F, so weather is not the weak point on this unit.
Because nothing is wired to the trailer, you are relying on a battery every single time. Owners of solar magnetic systems across this category report topping up overnight before a big trip, and the pattern holds here.
3. AUTO-VOX Solar3A Plus 7.2 Inch Dual Camera Kit
AUTO-VOX 2 Solar Wireless Backup Cameras, 2-Min DIY Install
Two solar wireless cameras with magnetic mounts
7.2 inch 16:9 split-screen monitor
1080p with color night vision
DVR loop recording
IP69K
Pros
- Two cameras cover front and rear blind spots simultaneously
- Very fast magnetic install with no wiring or lamp tapping
- Stable signal through city streets and wooded areas
- Color night vision rather than washed-out infrared
- DVR loop recording locks collision clips
Cons
- Highest ticket in this roundup for the dual-camera bundle
- Solar output is limited so batteries need regular charging
- Battery depletes over long days of continuous use
- 7.2 inch screen needs careful dash placement
The AUTO-VOX Solar3A Plus is the only kit here that ships with two cameras, and that changes what the system can do. Both cameras mount magnetically anywhere you want a view, and the 7.2-inch 16:9 monitor shows them side by side on a dual-channel simultaneous split screen. For spotting pedestrians beside a long rig, having a second angle is worth more than any single-spec upgrade.
Install takes about two minutes with no wiring, no drilling and no tapping into a lamp circuit. Both cameras are solar with rechargeable batteries, and the monitor sleeps on configurable timers of 120 seconds, 240 seconds or never.
Night is where this kit separates itself. Rather than the washed-out grey of infrared, AUTO-VOX specifies color night vision at 1080p, and owners confirm the low-light image retains color instead of flattening to monochrome. The 170-degree field of view covers nearly the full width of a trailer’s rear.
Recording is a genuine strength. DVR loop recording captures to microSD, and collision clips can be locked so a bump in a parking lot does not get overwritten by the next twenty minutes of driving.
What you should check before buying
Measure the dash twice before this one goes in. A 7.2-inch screen in a compact pickup or small SUV needs deliberate placement, and owners specifically call out needing careful positioning. The visor mount option matters more at this size.
Also plan a charging routine. Owners report that the solar panel’s output does not keep pace with heavy use, so on a long trip you will be charging overnight. Treat the solar panel as a trickle top-up rather than a primary supply.
Where it falls short
Of the eleven systems we looked at, this bundle carries the highest ticket, and that is worth weighing against buying one antenna-based camera instead. If your needs are a single rear view on a mid-size trailer, the premium buys you features you may never switch on.
Battery depth of discharge after extended operation is the other recurring complaint, and warranty support has been responsive when units have needed replacing.
4. DOUXURY 1080P 170 Degree IP69 System
RV Backup Camera Wireless DOUXURY IP69 Waterproof 170° Wide View Angle HD 1080P Rear View Camera + HD LCD 7″ Monitor, Digital Wireless Camera System for RV Truck 5th Wheel Trailer Pickup Camper Bus
7 inch LCD monitor
1080p CCD image chip
320ft open area, 180ft through vehicles
IP69 waterproof
Four channels
Pros
- Strong signal holds up even with metal bodies between camera and monitor
- Bright clear color picture in daylight and at night
- No wiring between monitor and camera so plugging in is easy
- Four-channel expansion for side and interior cameras
- Fast installation with clear directions
Cons
- Live frame rate of roughly 15-20fps produces jerky motion
- DVR recordings stop unpredictably and save at 1280x720
- Recorded footage is mirrored side to side
- Suction monitor mount can detach on rough roads
- One owner reported water ingress at the lens
The DOUXURY D-1T1 earns its place through consistency. It holds the highest average rating of any system here at 4.4, and the reason owners give is a picture that stays bright and colorful in both daylight and darkness. The 1080p CCD image chip and 0.1 lux rating do work that CMOS sensors in cheaper kits often fumble.
On signal, the dual-antenna design is rated at 320 feet in open areas and 180 feet through vehicles. Owners with metal-bodied trailers report the image holding even with the trailer physically between the camera and the monitor, which is the scenario that trips up lesser systems.
The monitor accepts four channels and displays quad screen, so you can run cameras at both rear corners plus a side and an interior view. Power is universal 12-24V DC with no wire between monitor and camera, and built-in reversing guideline lines help with alignment. It is compatible with RVs, semi trailers, box trucks and trailers.
At two pounds, the whole package is light enough to move between vehicles without thinking about it. Owners frequently compare the cost favorably against factory systems that perform similarly.
What you should check before buying
Decide early whether you care about recording. If DVR evidence matters to you, this is not the system. The recording function is the weakest part of an otherwise strong package, and if you need dash-cam quality, the Yakry or AUTO-VOX kits record more reliably.
Mount the monitor somewhere firm. The included suction cup mount is the flimsier point on this unit, and owners on rough roads report it detaching. A dash adhesive mount or a visor bracket solves it in a minute.
Where it falls short
The live frame rate sits around 15-20fps, which produces visible jerkiness during fast reversing. It is fine for slow alignment work and noticeably less so when you are creeping backward at speed in a tight site.
Recorded clips also stop unpredictably and save at 1280×720 rather than the full 1080p the sensor captures, and playback is mirrored side to side. One owner reported water ingress at the lens after heavy rain, which is an isolated report but worth knowing about given the IP69 claim.
5. AUTO-VOX SOLAR5-JP 7.2 Inch Solar Magnetic DVR
AUTO VOX Wireless Backup Camera Solar Magnetic, 7.2″ DVR 1080P Monitor
524ft dual-antenna range
Magnetic base with rubber wrap and metal plate
Solar panel with 20 hours of use
1080p IR night vision
IP69K
Pros
- Crisp image with no lag
- works as a digital rearview while towing
- Very fast magnetic install including an adhesive plate for aluminum
- Responsive replacement support when a unit failed
- 20 hours of battery runtime from a charge
Cons
- Magnet can release on rough roads at highway speed
- Large exposed camera is an easy theft target when unattended
- Included USB-C plug is too short to seat properly
- Screen could be brighter in direct daylight
- Solar charging needs overnight USB top-ups
The SOLAR5-JP solves the problem that makes most solar magnetic cameras frustrating on longer rigs: range. AUTO-VOX rates the dual-antenna link at up to 524 feet, which puts it in antenna-system territory while keeping the tool-free magnetic install and self-contained power.
The mount is a magnetic base wrapped in rubber, and AUTO-VOX includes a metal adhesive plate for non-magnetic surfaces like aluminum or wood-framed trailers. The solar panel with rechargeable battery gives up to 20 hours of continuous use, with auto sleep options at 120 seconds, 240 seconds or never.
Image is 1080p with IR night vision from a CMOS IR sensor across a 170-degree field of view. Owners describe using it as a constant digital rearview mirror while towing, with a crisp feed and no perceptible lag, which is a different use pattern than simply reversing.
DVR loop recording to microSD is included, and the package ships with a carrying case. The whole unit weighs about 450 grams, light enough to move between a truck and an RV without ceremony.
What you should check before buying
Test the magnet on your actual trailer surface before you rely on it at speed. Owners report the mount letting go on rough roads at highway speed, and the fix is the included adhesive plate rather than more pressure on the magnets.
Also think about where the camera lives when the trailer is parked. This is a large exposed unit on the outside of the trailer, and reviewers flag it as a theft target when left unattended for days at a campground. A hitch lock or a small deterrent helps.
Where it falls short
The included USB-C cable is short enough that the plug does not seat properly in some cameras, which turns a charging problem into a return. Budget for your own cable.
Screen brightness in direct daylight is a recurring note, and solar charging is best treated as a supplement to overnight USB charging rather than a standalone supply. This is the single-camera version; the dual-camera variant is sold separately, so add it only if you have the range for it.
6. nuoenx 7 Inch System with 18 LED IR Night Vision
Nuoenx Wireless Backup Camera, 7 Inch Monitor Rear View Camera System for RV, Trailers, Trucks, 5th Wheels, Support 2 Cameras, IP69 Waterproof 18 LED IR Night Vision 152° View Camera, DIY Guide Lines
18 LED infrared night vision
0.01 lux low-light rating
7 inch TFT-LCD monitor
2.4GHz digital wireless
IP68K waterproof
Pros
- Stable 1080p image without interference from other wireless devices
- Wired-power camera means no battery charging to worry about
- Suction cup mount avoids drilling into the dash
- Night vision reaches about 60 feet in darkness
- Supports a second camera for dual coverage
Cons
- Camera must be wired to tail
- running
- license plate or backup lights
- Continuous-use range is only about 36 feet
- One year manufacturer warranty
- Second camera sold separately
Night vision is the reason to look at the nuoenx. Eighteen infrared LEDs and a 0.01 lux low-light rating put it well ahead of the kits that ship with eight or nine, and owners report usable night vision out to roughly 60 feet. If you back into unlit sites regularly, LED count is a spec worth reading before anything else.
The camera itself is wired for power, tapping into tail, running, license plate or backup lights, but the link to the 7-inch TFT-LCD monitor is wireless over 2.4GHz digital transmission. That split is a sensible design: no battery to maintain, no charging routine to keep up with.
The optical package is a 152-degree view angle behind a six-element glass lens on a CMOS sensor at 1080p. Working temperature runs from -4F to 176F on 12V-24V, and the camera carries an IP68K waterproof rating.
A suction cup mount puts the monitor on the windshield or dash without drilling, and a C button on the screen switches to a second camera when you add one. Split screen works as expected once that second unit is in.
What you should check before buying
Confirm you are comfortable running a power wire to the camera. Owners who already have a wired camera port, or who do not mind splicing into the running-light circuit, get a system that never runs out of power mid-backup.
Note the continuous-use range figure of about 36 feet, which sits alongside 300 feet in open area and 50 feet while actively reversing. For typical trailer lengths that is sufficient, but it is well short of what the antenna-based systems deliver.
Where it falls short
The one year manufacturer warranty is the shortest coverage in this group, so budget for a possible replacement sooner than you would with the three-year Rohent or the two-year pemacom and Losuudy coverage.
Because the camera must be physically wired, this is not a renter-friendly or storage-friendly option. If the trailer goes into covered storage, you are disconnecting a live wire each time rather than peeling off a magnet.
7. Rohent R12 Four Channel System with Furrion Adapter
Rohent RV Backup Camera Wireless HD 1080P Waterproof Dual Antennas Digital Signals Rear View System for Trailers Trucks Motorhomes 4 Channels 7” Touch Key DVR Monitoring Night Vision R12
980ft open-area and 320ft on-vehicle range
Four wireless channels with quad screen
7 inch touch monitor with DVR
IP69 waterproof
3 year warranty
Pros
- Excellent range even with camera and monitor far apart on long rigs
- Video quality rivals much more expensive factory systems
- Furrion pre-wire adapter makes install very quick
- Four-channel monitor with quad screen for multi-camera setups
- Responsive and helpful customer service
Cons
- No microphone so no audible reversing cues
- Very thin power leads are difficult to crimp
- Suction cup monitor mount breaks over time
- Menu settings and manual are not very clear
- Monitor power button does not stay off
The Rohent R12 has the highest average rating in the group at 4.5, and its range figures are the most generous on paper by a wide margin. The dual-antenna design is rated at 980 feet in open areas and 320 feet on a vehicle, which means the signal budget is not what limits you on a 40 or 55-foot rig.
That headroom matters because the four wireless video channels support full, split and quad screen modes. Owners running long combinations describe the picture holding when the camera and monitor are physically far apart, which is precisely where cheaper dual-antenna systems start to stutter.
A Furrion pre-wire adapter is included, so on a pre-wired trailer the install is quick. Compatibility runs to trucks, buses, box trucks, semi trailers, tractors and motorhomes, and the 3 year manufacturer warranty is the longest coverage here.
The 7-inch touch monitor includes a DVR recording function, and the 1080p CMOS sensor covers a 150-degree field of view. IP69 sealing and a -23F to 179F operating range handle northern winters without complaint.
What you should check before buying
Plan the monitor mounting properly before it arrives. The suction cup mount is the part owners complain about most, and on an SUV the windshield arrangement can be awkward to reach while seated. A fixed dash or visor mount is a worthwhile addition.
Read the manual before you need it. Owners describe the menu system as not very clear, and figuring it out under time pressure at a campground is a worse experience than twenty minutes with the instructions on a table.
Where it falls short
There is no microphone on the camera, so there are no audible reversing cues. If you rely on beeping proximity alerts, add that expectation to the purchase.
The power leads are thin and difficult to crimp, and the monitor power button does not stay off, which can drain an auxiliary battery over a long storage period. Both are small annoyances rather than dealbreakers on an otherwise well-built system.
8. VOONOA VN003 Magnetic Solar Hitch Camera
Wireless Magnetic Backup Camera, 15000mAh Battery Powered Rechargeable Waterproof HD Solar Back Up Rear View Bluetooth Hitch Camera with 7 Inch 1080P Monitor System for Car Truck Trailer RV VN003
15000mAh battery with solar assist
Six strong magnets on the base
120ft range in confined environments
7 inch 1080p IPS monitor
Remote camera power from monitor
Pros
- Six strong magnets hold firm even over rough roads
- Signal reaches 100 feet or more with obstructions
- Monitor shows signal strength
- battery level and charge status per camera
- Camera can be powered on from the monitor
- Two year replacement warranty honored quickly
Cons
- Battery lasts about 4-5 hours of continuous use and needs overnight charging
- Solar panel too weak to keep up with use
- Cameras may need a manual power-button press to re-pair
- Screen is hard to read through polarized sunglasses
- Magnets do not grip aluminum skins without screws
- 170 degree view makes the rear view less useful while travelling
The VN003 solves a small problem that annoys people constantly: turning the camera on. The camera is powered on and off from the monitor, so if the battery dies overnight you are not walking back to the trailer at dawn. For hitching up alone, that alone is worth having.
The on-screen status display is also unusually informative. It shows signal strength, battery level and charge status for each camera, which turns a vague “it stopped working” into an actual diagnosis you can act on. Six strong magnets in the base hold through rough roads, and the wireless range is up to 120 feet in confined environments.
IR night vision image quality is good, and the 7-inch 1080p LCD monitor powers from a cigarette lighter with a fast charger included. Coverage is RV, truck, trailer, camper and fifth wheel, in one or two camera configurations.
The warranty is a 60-day money-back window, two-year replacement and unlimited tech support, and owners describe that replacement service as honored quickly.
What you should check before buying
Be realistic about battery expectations. Owners report roughly 4-5 hours of continuous use and an overnight charge to keep going, and the solar panel is described as too weak to run the camera alone. If you back up multiple times a day for days on end, factor in a charging plan.
Test the magnet on aluminum before you rely on it. Owners report the magnets do not grip aluminum trailer skins without screws, which is a common skin material on modern trailers. The AUTO-VOX SOLAR5-JP includes an adhesive metal plate for exactly this case.
Where it falls short
The screen is difficult to read through polarized sunglasses, which is a real problem for anyone who drives wearing them. The 170-degree view is also so wide that the rear view becomes less useful while you are travelling.
After a full battery depletion, cameras sometimes need a manual power-button press to re-pair, and antenna placement limits how far you can adjust the camera’s aim angle.
9. DoHonest R50 Solar Magnetic Hitch Camera with 5 Inch Monitor
Wireless Backup Camera Solar Magnetic: Portable Cordless Scratch-Proof Truck Trailer Hitch Rear View Camera HD 1080P No Wiring No Drilling Rechargeable 5” Monitor Kit for Car RV Camper – DoHonest R50
9600mAh battery with solar charging
Neodymium no-scratch magnetic mount
16 IR LEDs
IP69K with scratch-resistant lens
5 inch IPS monitor
Pros
- Very easy magnetic setup with USB charging and simple pairing
- Strong magnet that stays put over rough roads
- Clear stable picture over long hauls
- Real-world range often exceeds the stated 35-36 feet
- Neodymium mount leaves no marks when removed
- Responsive customer service
Cons
- Camera and monitor can occasionally lose connection for a few seconds
- 5 inch screen is small against 7 inch rivals
- Camera is somewhat heavy for a magnetic mount
- Solar charging is largely untested by most owners
- Split-screen images are squeezed with two cameras
The DoHonest R50 is the one to consider if a 7-inch monitor is too much hardware for your vehicle. At 5 inches with an IPS panel and adjustable brightness, contrast and saturation, it mounts on a visor or a small dash without dominating your sightlines.
The mount is a neodymium magnetic base with a scratch-resistant lens cover, and owners confirm it leaves no marks when you pull it off. The 9600mAh rechargeable battery with solar charging gives up to 24 hours of use, and 16 IR LEDs with an auto light sensor handle night driving.
Range is the surprise. The stated figure is 36 feet with anti-interference technology, but multiple owners report real-world performance beyond the 35-36 foot claim on trailers and horse trailers. Rated IP69K with a scratch-resistant lens, it is built for weather exposure.
Parking assist distance lines are integrated into the display, and the package includes a 1-year warranty with lifetime tech support. Coverage lists cars, RVs, campers and trailers, with the split screen supporting a second camera.
What you should check before buying
Accept that the connection will blink out occasionally. Owners describe the camera and monitor losing contact for a few seconds and then recovering on their own, which is usually the auto sleep mode cycling rather than a failure.
If you plan to run two cameras, look at the split screen in person if you can. Owners report the two images are squeezed on the 5-inch panel, and the compression makes side-by-side judgment harder than it should be.
Where it falls short
The camera is somewhat heavy for a magnetic mount, which makes the fit at the top of the trailer frame more important than with a lighter unit. Check it holds before you trust it on the road.
Solar charging is largely untested by most owners, who treat the panel as decoration and charge over USB. The five-inch screen is the other tradeoff, and it is a real one for anyone judging distance by sight.
10. EWAY WiFi Magnetic Hitch Camera for Multi-Vehicle Use
EWAY Wireless WiFi Magnetic Hitch Backup Camera 1080P HD Rechargeable Battery Powered No Wiring Rear View Reverse Monitoring Camera for Car Truck Pickup RV Camper 5th Wheel Horse Trailer Boat Trailer
Four magnets rated at 15lbs pull each
100ft open-area wireless range
1080p with 9 IR lights
Two-channel 5 inch split screen
IP68P waterproof
Pros
- Very strong four-magnet hold on flat metal surfaces
- Truly wireless install with nothing to wire to the trailer
- Camera moves easily between vehicles and mounting positions
- Two-channel split screen allows a second side or front view
- IP68P rating allows brief submersion protection
- Adjustable DIY guide lines
Cons
- Recommended for vehicles under 60 feet
- 5 inch monitor is on the small side
- Requires frequent recharging of the camera battery
- Only nine IR LEDs for night illumination
The EWAY is built around one idea: one camera, several vehicles. With four magnets rated at 15 pounds of pull each, it grips flat metal surfaces firmly and comes off cleanly, which makes it the easiest unit here to move between a truck, a camper and a horse trailer in the same afternoon.
There is nothing to wire to the trailer at all. The 5-inch monitor powers from a cigarette lighter, and the 1080p image uses a CCD CMOS sensor across a 150-degree field of view with 9 IR lights and an auto light sensor for night.
The IP68P rating is unusual. It means the camera is submersible to 1.5 meters for 30 minutes, which covers boat launch ramps and pressure washing in a way that IP68 alone does not promise. The unit carries US Patent 10,894,515.
Two-channel split screen supports a second side or front view camera, and DIY adjustable guide lines let you set the reference marks yourself instead of working around the factory ones.
What you should check before buying
Read the stated ceiling: EWAY recommends this camera for vehicles under 60 feet. That is generous for a magnetic system and covers nearly every trailer in this guide, but it does mean the very longest fifth-wheel combinations are outside what the manufacturer tested.
Plan charging around your use. Owners report needing to recharge the camera battery regularly, and there is no separate battery pack in the box. For someone backing up three times a day for a week, that becomes the deciding factor.
Where it falls short
Nine IR LEDs is the smallest night-vision array in this roundup, and it shows in genuinely dark campsites. If night backing is a frequent task, the nuoenx with 18 LEDs or the DoHonest with 16 is a better bet.
The 5-inch monitor is on the small side for judging distance to an obstacle at the trailer’s corner, and the 100-foot open-area range is modest once a metal trailer body sits between camera and monitor.
11. Losuudy 5 Inch Magnetic Solar System for Trailers and Work Equipment
Magnetic Solar Wireless Backup Camera with 5” HD Monitor No Wiring Rechargeable Battery IP68 IR Night Vision Rearview Camera System for Car RV Truck 5th Wheels Skid Steer Horse Trailer Hitch Camera
Three minute no-drilling magnetic install
10000mAh battery for 18 plus hours
IP68 with 10 IR LEDs
About 40ft effective range
720p capture resolution
Pros

The Losuudy is the odd one out in the best way. It is built for equipment as much as for trailers, and owners use it on skid steers, tractors and farm gear where nothing but a magnet would survive. Installation takes about three minutes with no wiring and no drilling.
Power is a 10000mAh rechargeable battery rated at 18 hours or more of use, with a six-hour fast charge. The solar panel is capped at roughly 0.8W, so treat it as an assist rather than a supply. An intelligent auto sleep mode kicks in when the monitor powers off.
Weather resistance is a genuine strength. IP68 sealing has held up for owners in rain, hail, wind and snow, and the two-year manufacturer warranty comes with responsive support. A dual split screen with parking lines is included on the 5-inch monitor.
The catch is image quality. Video capture resolution is 720p, the lowest number in this roundup, across a 150-degree viewing angle on a CMOS sensor with 10 IR LEDs for night. It is perfectly serviceable for alignment work.
What you should check before buying
Be honest about whether 720p is enough. For aligning a hitch ball and backing into a familiar site, yes. For reading a license plate or picking out a distant obstacle at night, the 1080p systems in this guide are a clear step up.
Check the effective range against your rig. The stated figure is about 40 feet, which suits utility trailers, boat trailers and equipment loads, and falls short for a 35-foot travel trailer.
Where it falls short
Solar charging contributes very little at 0.8W, so you will charge this over USB between uses. Owners who expect the panel to sustain week-long camping rely on the wall charger instead.
The 5-inch monitor is compact, which keeps it out of the way but gives you less visual resolution than the 7-inch competitors. On a work machine where the screen sits further from the operator’s eyes, that is a genuine limitation.
How to Choose a Wireless Backup Camera for Your Trailer
Match your trailer length to a rated range
Wireless range is advertised two ways, and confusing them is the most common buying error in this category. Open-area range assumes clear line of sight with nothing between camera and monitor. On-vehicle range assumes the trailer’s own metal body sits in between, which is what actually happens when you tow.
Use the on-vehicle figure, not the headline number. Here is how it lines up against rig length:
Up to 20 feet total (boat, utility or small trailer): a 33-40 foot system is genuinely sufficient. The pemacom, DoHonest and Losuudy all work here.
20 to 30 feet total (mid-size travel trailer with a pickup): aim for at least 100 feet through obstructions. The VOONOA at 120 feet and the EWAY at 100 feet open-area both hold up, as do the antenna-based units.
30 to 45 feet total (large travel trailer or fifth wheel): you want 300 feet or more through vehicles. The Yakry at 320 feet, Rohent at 320 feet and DOUXURY at 180 feet fall into this band.
45 feet and up (toad, double fifth wheel, 55-foot combination): only the dual-antenna systems with generous on-vehicle ratings belong here. The Rohent R12 at 980 feet open-area with 320 feet on-vehicle gives the most headroom in this roundup.
Owners running long rigs consistently report that short-range magnetic systems work fine for hitching but struggle once the trailer is fully behind the tow vehicle and you are easing backward. Match the system to the longest scenario, not the most common one.
Choose solar versus hardwired power
Solar magnetic systems trade install effort against reliability. A magnetic unit goes on in one to three minutes and requires nothing but charging, which makes it the right answer for renters, boat trailers, and anyone who swaps cameras between machines. Hardwired systems take an afternoon but never run out of power mid-campfire-dark-backup.
The honest limitation is that nearly every solar system in this roundup underdelivers on panel output. Losuudy’s panel is rated at roughly 0.8W, and VOONOA owners report the solar cannot run the camera alone at all. Plan on charging over USB overnight between trips and treat solar as a trickle that extends idle time.
One useful middle path: buy a magnetic solar system and wire only the monitor, which draws from your cigarette lighter or a dash USB port. That is where the AUTO-VOX SOLAR5-JP and the pemacom P15 both land, and it keeps the expensive camera side cord-free.
Read the dual antenna and IP ratings carefully
Two definitions get mangled in this category, and both matter.
IP68 means the unit resists dust ingress and continuous immersion in water deeper than 1 meter for a specified duration. IP69K means it withstands high-pressure, high-temperature water jets close up, which is the standard for equipment that gets pressure-washed. If you wash your trailer or run it through a car wash on a regular basis, IP69K is the rating to insist on. The Yakry, AUTO-VOX kits, DoHonest and Losuudy carry IP68 or above; the DOUXURY, Rohent and nuoenx carry IP69 or IP68K respectively.
On antennas, the pattern across these products is consistent: single-antenna systems cluster around 33 to 120 feet, while dual-antenna designs reach 180 to 980 feet in open area. If your trailer is 30 feet or longer, treat dual antennas as a requirement rather than a preference.
Count IR LEDs before you count anything else for night use
Night complaints are the loudest thread across RV forums, and the cause is usually LED count. Systems here run from 8 IR lights on the Yakry to 18 on the nuoenx, with the DOUXURY at 0.1 lux, the pemacom using an F1.2 aperture, and the AUTO-VOX dual kit offering color night vision instead of monochrome infrared.
If you back into unlit campsites more than once a month, put LED count and sensor lux rating ahead of screen size in your decision. A 5-inch screen with 18 IR lights will beat a 7-inch screen with 8 every time in a dark campsite. One note on etiquette: bright infrared arrays are visible to neighbours, so aim the camera down and keep it off when you are parked for the evening.
Size the monitor for your cab
Monitor placement determines whether a camera gets used daily or abandoned in a drawer. Dash or windshield mounting keeps the screen in your line of sight while reversing. Visor mounting keeps it out of the way of the road but slightly higher. Mirror-style mounting works well if your vehicle already has a mirror-style monitor bracket.
A 7-inch or 7.2-inch screen needs deliberate placement in a compact pickup or small SUV, and owners of the AUTO-VOX and Yakry systems specifically mention crowding. A 5-inch IPS panel from the DoHonest, EWAY or Losuudy is far easier to live with daily.
Check factory camera ports before you buy
If your trailer shipped with a factory camera, find out whether the port is a Furrion-style pre-wire or a proprietary connector before you order. The Yakry Y27 and Rohent R12 both include a Furrion bracket or pre-wire adapter, which turns the install into a short job. On a proprietary system, an aftermarket unit may need a completely separate harness.
Owners on r/GoRVing ask this question constantly because the wrong answer means a return. Spending ten minutes with the trailer’s build sheet or a flashlight and a pair of pliers at the existing camera mount is cheaper than shipping a system back. If you want the fixed, always-on camera that comes with the trailer rather than a portable one, our boat trailer comparison covers the same mounting decisions for a much smaller rig.
Installation and Troubleshooting
Five steps to fit a magnetic solar camera
Clean and dry the mounting surface. Wipe the trailer frame with a degreaser and let it dry fully. Magnetic grip depends on flat, clean metal, and a dusty frame is the most common cause of a camera coming loose.
Charge the camera fully before the first use. Most owners who complain about battery life charged partially and assumed the worst. A full five to six hour charge establishes the real baseline.
Mount the camera where the view is unobstructed. Aim slightly down and outboard so the frame edges and the ground beside the trailer are both in view. Check for a spare tire, a ladder or a light bar blocking the lens.
Pair the camera to the monitor before mounting permanently. Pairing is easier with the camera in your hands and the monitor powered from the cigarette lighter. Confirm you get a live image in daylight before you commit to a mounting position.
Test the magnetic hold at speed. Drive a short loop on a rough surface. If the camera shifts at highway speed, add the adhesive metal plate and re-test before backing anything up.
Four steps when the camera has power but no signal
This is the most repeated question across trailer forums, and the diagnosis is usually short. Work through these in order rather than replacing hardware first.
Confirm both ends are on the same channel.Magnetic solar systems often re-pair after a battery depletes. Power cycle the camera with its own button, then check the monitor still lists it.
Move the monitor antenna before anything else. Antenna position, not antenna count, is the leading cause of a powered camera with no picture. Get the monitor antenna up and away from the vehicle’s roof and any metal bodywork.
Rule out a competing 2.4GHz device. Other wireless cameras, baby monitors, cordless tools and some tire-pressure systems sit in the same band. Power them off one at a time and see whether the image returns.
Check the vehicle lights if the camera is hardwired. Trailer-powered cameras draw from the running-light circuit. If the image fails only at a campsite with the lights off, that is the whole problem, and a red wire to the backup circuit resolves it.
If the signal holds at a campground but fails on the highway, it is a range or obstruction problem, and the fix is moving up to an antenna-based system rather than adjusting settings. If it drops only in heavy rain, look at the seal around the mount instead.
Frequently Asked Questions
What is the best wireless back-up camera for a travel trailer?
For most travel trailers, the Yakry Y27 is the strongest all-round choice because it is pre-wired for Furrion ports, holds a dual-antenna signal rated to 320 feet on a vehicle, and ships with a bright 7-inch touchscreen and 1080p image. If your trailer has no factory camera port, the pemacom P15 installs magnetically in about a minute with no wiring.
What are some good wireless back-up cameras for trailers?
The eleven systems in this guide cover most needs: the Yakry Y27 for pre-wired trailers, the Rohent R12 for very long rigs, the AUTO-VOX Solar3A Plus for two-camera split-screen coverage, the DOUXURY for a bright wide picture, the nuoenx for 18 LED night vision, and the pemacom, AUTO-VOX SOLAR5-JP, VOONOA, DoHonest, EWAY and Losuudy magnetic solar kits for tool-free installs.
What is the best magnetic back-up camera for a trailer?
The AUTO-VOX SOLAR5-JP is the best magnetic choice for trailers longer than about 25 feet, because its dual-antenna link is rated to 524 feet while still mounting with no wiring. For shorter rigs, the pemacom P15 installs in about a minute and the AUTO-VOX SOLAR5-JP includes an adhesive metal plate for aluminum trailer skins that magnets cannot grip.
Who makes the best wireless backup camera?
In this roundup, AUTO-VOX builds the most capable magnetic systems and the Yakry the best pre-wired unit, with Rohent leading on long-range antenna performance. Forum consensus across RV and trailer communities also names Haloview and Furrion repeatedly, and factory Furrion Vision S systems are widely reported as reliable, though none of the eleven systems reviewed here came from those two brands.
Are wireless backup cameras any good, or do they drop out constantly?
They hold up well when the rated range matches the rig. Dual-antenna systems rated at 180 to 320 feet through vehicles stay locked on long trailers, while single-antenna magnetic units rated at 33 to 120 feet work for short rigs and can drop out once a long trailer sits between camera and monitor. Matching the on-vehicle range figure to your trailer length is the deciding factor.
How far can a wireless trailer camera transmit?
It depends on which figure you read. Open-area ratings here run from 100 feet on the EWAY to 980 feet on the Rohent R12, but open-area numbers assume clear line of sight. Through-vehicle ratings are the realistic ones, running from 33 feet on the pemacom P15 to 320 feet on both the Yakry and the Rohent.
Conclusion
The best wireless backup cameras for trailers come down to one number: how long is your rig, and does it have a factory camera port. Pre-wired trailers should start with the Yakry Y27, which pairs a Furrion-ready install with a 7-inch touchscreen and a 320-foot on-vehicle range. That is our pick for a reason, and it stays the recommendation through 2026.
Long combinations over 45 feet should look at the Rohent R12, whose 980-foot open-area rating and four channels give the most headroom of anything here. Shorter trailers and boats should consider a magnetic solar unit, with the pemacom P15 for the fastest install and the AUTO-VOX SOLAR5-JP if the trailer runs past 25 feet.
Night backing is the one area worth researching before you commit. Count the IR LEDs, aim the camera down to keep the light off your neighbours, and test the image in a genuinely dark spot before the trip. Owners of factory Furrion systems often weigh replacing them against a quality aftermarket kit, and if your trailer is a boat or a single axle utility rig, our solar power guide covers the off-grid charging kit that keeps a spare battery ready between trips.
