Alternatives to Waterproof Backup Cameras That Work

Reversing an RV or a truck with a trailer is guesswork without a camera, and the camera that works on a car often fails on a long rig, where the signal drops and the battery dies.

Waterproof backup cameras split into two families: solar and magnetic cameras that install in a minute and move between vehicles, and fixed license-plate cameras that are wired once and forgotten.

This guide compares five verified waterproof backup cameras that work, from a solar AUTO-VOX to a dual eRapta, with the honest limits of each one printed alongside the pick.

Waterproof backup cameras compared

How to choose a waterproof backup camera

Six points decide the purchase, and the first one matters most: match the range to the length of the vehicle before anything else. The same buy-once logic runs through our heavy-duty truck winch guide and our what size winch guide.

Wireless range on the vehicle

A camera that works in open space may fail on a long RV, where steel blocks the signal. The eRapta cameras promise 320 feet in open space but 40 feet on a vehicle, so match the on-vehicle range to the length of the rig, not the open-space number.

Power: solar, battery or wired

Solar never needs charging but depends on sun, battery lasts a long tow but must be charged, and wired never runs flat but takes longer to install. Choose the power source for the parking and the towing the vehicle actually does.

Monitor size and recording

A 5-inch monitor suits a car, a 7-inch monitor suits an RV, and a DVR monitor records the feed. A bigger monitor is easier to read while reversing, but it takes more dash space. Match the monitor to the vehicle, not the wish list.

Waterproofing that survives washing

IP69K means the camera survives rain and high-pressure washing, while a lower rating may not. A backup camera lives outside in all weather, all year, so the waterproof rating matters more than the resolution. Check the waterproof rating before the price.

Mount: magnetic, license plate or fixed

A magnetic mount moves between vehicles in a minute, a license plate mount is fixed and neat, and a wired camera is permanent. Choose the mount for how often the camera moves, and check that the surface is steel if the mount is magnetic.

Night vision that actually works

Night vision needs either IR LEDs or the headlights on, and the two are not the same. The eRapta ACT501 has 16 IR LEDs, while the ERT01 needs the headlights on. Check how the night vision works before buying for night use.

Backup cameras by budget

The tiers below assume the vehicle already has a display or a monitor is included. The recovery side of the same workshop is covered in our come-along winch guide.

Types of waterproof backup cameras

Five approaches cover the whole job, and most owners need only one of them. The same sizing maths runs through our best truck winches guide and our Honda Pioneer 1000 winch guide.

Best Overall Wireless Camera: AUTO-VOX W7Pro Wireless Backup Camera

Best Overall Wireless Camera

Why this is our pick

The AUTO-VOX W7Pro is the all-rounder in this guide, a wireless backup camera with a 5-inch HD monitor, a stable digital signal and dual channel color night vision. The listing names cars, pickups, SUVs, vans and trucks, so most vehicles are covered, and the wireless design means the install is easy, with no long video cable to run through the vehicle. Trustpilot rates AUTO-VOX 3.7 out of 5 from 64 reviews, with owners praising the easy setup and the clear picture. The honest complaint is support: owners report unanswered support emails, batteries failing after months and a 12V lead that does not fit, so buy it for the hardware, not the aftercare.

Key specs

• Monitor: 5 in HD
• Signal: Wireless, stable digital signal
• Channels: Dual channel
• Night vision: Color night vision
• Use: Cars, pickups, SUVs, vans and trucks
• Install: Easy install, no long cable run
• Waterproof: Not published in sources captured
• Power: Not published in sources captured
• Best for: Trucks and pickups that need a wireless camera
• Warranty: Not published in sources captured

Fits and best for

Owners of a truck, pickup, SUV or van who want a wireless camera with a dedicated monitor. The 5-inch HD monitor sits on the dash, the dual channel covers the rear and a second view, and the wireless link means no cable run through the vehicle. It suits a work truck, a family SUV or a van that tows.

Pros and watch-outs

What owners report

Who should not buy

Skip it if the vehicle needs a solar camera with no charging at all, or if the job needs two cameras at once. The Solar3A Plus below or the dual eRapta below are the honest buys then.

Pair it with

A 12V cigarette lighter adapter as a spare power lead, and a pack of cable ties for the monitor cable. The camera is wireless; the monitor still needs power.

Tip: Test the signal with the engine running before the first drive, since interference shows up then. Our how to mount a winch guide makes the same point about testing before trusting.

Best Solar Backup Camera: AUTO-VOX Solar3A Plus Wireless Backup Camera

Best Solar Backup Camera

Why this is our pick

The AUTO-VOX Solar3A Plus is the solar camera in this guide, with two wireless cameras, a 7.2-inch 1080P DVR monitor, IP69K waterproofing and a 140-degree lens. The Van Conversion’s review of the Solar 3A Plus notes a two-minute install, a 12V cigarette plug and virtually no lag, and Auto Roamer’s wireless backup camera buyer’s guide points most people to the AUTO-VOX Solar camera first. The solar panel keeps the battery charged, so the camera works without wiring or charging. The honest limit is the same as any solar camera: cloudy weeks and shaded parking drain the battery, and the Trustpilot complaints about AUTO-VOX support apply here too.

Key specs

• Monitor: 7.2 in, 1080P DVR
• Cameras: 2, dual channel
• Lens: 140 degrees
• Waterproof: IP69K
• Power: Solar plus battery
• Install: 2-minute install
• Mount: License plate mount
• Plug: 12V cigarette plug
• Lag: Virtually no lag
• Best for: RVs, trailers, trucks and SUVs

Fits and best for

Owners of an RV, trailer, truck or SUV who want a camera that never needs charging and never needs a cable run. The solar panel keeps the battery topped up, the two cameras cover the rear and a second view, and the 7.2-inch 1080P DVR monitor records the feed. It suits a motorhome, a travel trailer or a truck that tows.

Pros and watch-outs

What owners report

Who should not buy

Skip it if the vehicle is parked in shade or under cover, where the solar panel will not charge, or if the budget only stretches to a single camera. The eRapta ERT01 below is the honest buy then.

Pair it with

A second 12V cigarette plug adapter, and a lens cleaning cloth. The solar panel charges the camera; a clean lens keeps the picture clear.

Tip: Park in the sun when the camera is not in use, so the solar panel keeps the battery topped up. Our winch battery guide makes the same point about keeping a battery charged.

Best Budget Backup Camera: eRapta ERT01 License Plate Backup Camera

Best Budget Backup Camera

Why this is our pick

The eRapta ERT01 is the budget camera in this guide, a 1080P license plate camera with a 149-degree lens and IP69K waterproofing. Pixelfy’s rear view camera guide lists it among its best cameras, noting the 1080P picture, the 149-degree angle and the night vision that needs the headlights on. It is a camera only, with no monitor in the box, so it connects to the car’s existing display, which keeps the price down and the install simple. The honest limit is the night vision: it needs the headlights on to see in the dark, and it is wired, so the install takes longer than a magnetic camera.

Key specs

• Resolution: 1080P
• Lens: 149 degrees
• Waterproof: IP69K
• Mount: License plate
• Night vision: Yes, needs headlights
• Monitor: Not included, uses the car display
• Use: Pickup trucks, cars and SUVs
• Install: Wired, license plate mount
• Best for: Owners who want a fixed camera
• Warranty: Not published in sources captured

Fits and best for

Owners who want a fixed camera that is wired once and forgotten, with no battery to charge and no solar panel to park in the sun. The license plate mount fits most cars, pickups and SUVs, and the 149-degree lens covers the rear. It suits a daily driver, a work pickup or a car whose display already has a camera input.

Pros and watch-outs

What owners report

Who should not buy

Skip it if the car has no display input for a camera, or if the owner wants a camera that moves between vehicles. The magnetic eRapta ACT501 below is the honest buy then.

Pair it with

A set of wire connectors and a pack of cable ties for the camera cable. The camera is fixed; the wiring must be tidy.

Check Price

We may earn a commission at no cost to you.

Tip: Wire the camera to the reversing lights, so it turns on with the gear, and check the night vision with the headlights on. Our ATV winch installation walkthrough makes the same point about wiring to the right circuit.

Best Magnetic Backup Camera: eRapta ACT501 Magnetic Wireless Backup Camera

Best Magnetic Backup Camera

Why this is our pick

The eRapta ACT501 is the magnetic camera in this guide, with a 5-inch monitor, a 9,600 mAh battery, Type-C charging and a 150-degree lens with 16 IR LEDs for night vision. BestReviews.guide lists it among its reviewed cameras, noting the FHD1080P picture and the 5-inch magnetic design, and the listing promises a 320-foot range in open space and 40 feet on a vehicle, with a one-minute install and a two-year replacement. The honest limit is the magnet: it needs a steel surface, so an aluminum trailer needs the iron sheet bracket, and the battery must be charged, unlike a solar camera.

Key specs

• Monitor: 5 in
• Battery: 9,600 mAh, Type-C
• Range: 320 ft open, 40 ft on a vehicle
• Lens: 150 degrees
• Night vision: 16 IR LEDs
• Waterproof: IP69K
• Install: 1-minute install
• Mount: Magnetic
• Replacement: 2-year replacement
• Best for: Trailers and vehicles that change often

Fits and best for

Owners who move the camera between vehicles, or who tow a trailer that changes. The magnetic mount sticks to any steel surface, the 9,600 mAh battery lasts through a long tow, and the one-minute install means no wiring at all. It suits a rental trailer, a farm truck or a driver with two vehicles and one camera.

Pros and watch-outs

What owners report

Who should not buy

Skip it if the trailer is aluminum, where the magnet will not stick without a bracket, or if the owner wants a camera that never needs charging. The solar AUTO-VOX above is the honest buy then.

Pair it with

An iron sheet bracket for aluminum surfaces, and a Type-C charging cable kept in the cab. The magnet sticks to steel; the bracket covers aluminum.

Tip: Charge the battery the night before a tow, and test the signal at 40 feet before hitching up. Our synthetic winch rope lifespan guide makes the same point about testing before the real job.

Best Dual-Camera Backup Camera: eRapta ACT702 Dual Magnetic Wireless Backup Cameras

Best Dual-Camera Backup Camera

Why this is our pick

The eRapta ACT702 is the dual-camera system in this guide, with two magnetic wireless cameras, a 7-inch DVR monitor, a 9,600 mAh battery and support for up to four cameras with split and quad screens. BestReviews.guide lists it among its reviewed cameras, noting the HD1080P picture and the 7-inch magnetic wireless design, and the listing promises a 320-foot range in open space, 40 feet on a vehicle, IP69K waterproofing and operation from minus 6 to 151 degrees. The honest limit is the same as any magnetic camera: it needs steel, and the 40-foot on-vehicle range means a very long trailer may need the cameras placed carefully.

Key specs

• Monitor: 7 in DVR
• Cameras: 2, dual magnetic
• Battery: 9,600 mAh
• Range: 320 ft open, 40 ft on a vehicle
• Waterproof: IP69K
• Temperature: Minus 6 to 151 degrees F
• Screens: Split and quad screens
• Supports: Up to 4 cameras
• Install: 1-minute install
• Best for: RVs, trailers and long trucks

Fits and best for

Owners of an RV, a long trailer or a truck that needs two views at once: the rear and a side, or the rear and the hitch. The two magnetic cameras stick where they are needed, the 7-inch DVR monitor records the feed, and the system supports up to four cameras. It suits a motorhome, a fifth wheel or a farm truck with a long trailer.

Pros and watch-outs

What owners report

Who should not buy

Skip it if the vehicle only needs one camera, where the single ACT501 above costs less and is simpler, or if the trailer is aluminum. The W7Pro above is the honest buy then.

Pair it with

Two iron sheet brackets for aluminum surfaces, and a Type-C charging cable for each camera. The cameras stick to steel; the brackets cover the rest.

Check Price

We may earn a commission at no cost to you.

Tip: Place the cameras so the signal travels the shortest path to the monitor, and test at 40 feet before the first tow. Our portable 12V winch guide makes the same point about testing the range before the real job.

How to install a waterproof backup camera

Choose the mount first: magnetic for a camera that moves, license plate for a fixed camera, or solar for a camera that never needs charging. For a magnetic camera, stick it to a clean steel surface, or fit the iron sheet bracket on aluminum. For a license plate camera, mount it on the plate and run the cable to the display, wiring it to the reversing lights so it turns on with the gear. For a solar camera, mount it in the sun and plug the monitor into the 12V cigarette socket. Pair the camera with the monitor, test the signal with the engine running, and check the night vision with the headlights on. Charge the battery the night before a tow. For the wider workshop habits behind this, our how to mount a winch guide and our ATV winch installation walkthrough cover measuring twice and working methodically. Cable care is covered in our attach cable to a winch drum guide and our winch cable replacement guide.

Safety essentials

Troubleshooting

Real-world notes

Backup cameras fail in the same few ways, and all of them are avoidable. The first is a lost signal, which shows up as a blank monitor on a long RV; the fix is to match the on-vehicle range to the rig and place the camera closer to the monitor. The second is a flat battery, which shows up as a camera that will not turn on; the fix is to charge it the night before a tow, or buy a solar camera. The third is a magnet that will not stick, which shows up on an aluminum trailer; the fix is the iron sheet bracket. Roundup writers report the same pattern across brands: owners who like a camera usually mention the easy install and the clear picture, and owners who dislike one usually mention the support or the battery. The same care applies to winch cable as to backup cameras: our electric boat anchor winch guide and winch amp draw guide cover rope care and the electrical side of the same workshop.

Who should NOT buy these

Vehicle already has a factory camera. If the car came with a backup camera, an aftermarket one adds little. These picks are for vehicles with no camera, or a camera that has failed; our handheld winch guide covers the heavy work.

Trailer is aluminum and no bracket is fitted. A magnetic camera will not stick to aluminum without the iron sheet bracket. Buy the bracket first, or choose a license-plate camera; browse the truck winch archive for the wider workshop class instead.

Budget is under a fixed camera. If the job is a single car with a display, the eRapta ERT01 is the cheapest honest buy. These picks are for owners who need wireless or solar; our ATV winch for plowing guide covers the same value question on the winch side.

Owner will not charge a battery. A battery camera that is never charged is dead weight. Buy a solar or wired camera instead, or the camera will fail on the first tow.

FAQ

What is the best waterproof backup camera?

For most owners, the AUTO-VOX Solar3A Plus is the answer: solar power, two cameras, a 7.2-inch 1080P DVR monitor and IP69K waterproofing. For a truck that needs a wireless camera, the AUTO-VOX W7Pro is the pick, and for a tight budget, the eRapta ERT01 is the honest buy.

Are wireless backup cameras reliable?

Yes, if the range matches the vehicle. Wireless cameras can suffer interference and dropouts on a long RV, so check the on-vehicle range, not the open-space number. The eRapta cameras in this guide promise 40 feet on a vehicle, which covers most trailers.

Can a backup camera work on an RV or trailer?

Yes, with a camera rated for the length. A magnetic wireless camera like the eRapta ACT702 suits an RV, since it installs in a minute and needs no cable run. A wired license-plate camera suits a car, but the cable run on a long RV is a big job.

How long does a magnetic backup camera battery last?

The eRapta ACT501 and ACT702 carry a 9,600 mAh battery, and the AUTO-VOX Solar 5B promises 100 days at 25 degrees Celsius. Real life depends on use and temperature, so charge the battery the night before a tow and keep a Type-C cable in the cab.

Do I need a solar backup camera?

A solar camera suits a vehicle that is parked in the sun and used often, since the panel keeps the battery charged. A battery camera suits a vehicle that is used rarely, and a wired camera suits a vehicle that is used daily. Match the power source to the parking.

What does IP69K mean on a backup camera?

IP69K means the camera is dust-tight and survives high-pressure water jets, which is the highest waterproof rating for a camera. It matters because a backup camera lives outside in rain, snow and car washes. A lower rating may fail in a storm or a wash.

Can I install a backup camera myself?

Yes, for a magnetic or solar camera, which installs in one or two minutes with no wiring. A wired license-plate camera takes longer, since the cable must run to the display. The AUTO-VOX Solar3A Plus installs in two minutes, and the eRapta ACT501 in one minute.

Why does my backup camera have no signal?

The usual causes are distance, interference and a flat battery. Check that the camera is within its on-vehicle range, that the battery is charged, and that the engine is running, since some cameras need the engine on. Move the camera closer to the monitor if the signal drops.

Do backup cameras work at night?

Yes, if the night vision is real. The eRapta ACT501 has 16 IR LEDs for night vision, while the ERT01 needs the headlights on. A camera with no IR LEDs and no headlights will show nothing in the dark, so check the night vision before buying.
