Best Backup Camera 2026: 5 Aftermarket Kits Compared
WriterPickly Editorial
Updated 2026-10-05
An aftermarket backup camera adds a rear view to a car, truck or trailer that lacks one. The main choice is how it gets power: from the reverse light wiring, from a battery with a solar panel, or as part of a mirror dash cam.
Quick answer
The AUTO-VOX Solar3A Plus at $129.99 is the backup camera for most drivers: a battery and solar camera with a 5-inch monitor and no wiring to run. The Solar3A Plus Max at $159.99 has a 7.2-inch screen and loop recording. The AUTO-VOX W12 at $99.99 takes power from the reverse lights. The eRapta AWTCM702 at $209.99 attaches by magnet for trailers. The WOLFBOX G840S at $169.99 is a 12-inch mirror dash cam with a rear camera.
We did not run our own testing on these cameras. Judging image quality and signal stability means installing each kit on the same vehicle and driving at night and in rain. What we did instead: took screen sizes, wireless range, battery capacity, viewing angles and waterproof ratings from each manufacturer's product pages, checked prices on the makers' own stores on October 4, 2026, and read owner reviews in volume. Range and battery life are the makers' own figures.
🏆 Best overall: The Solar3A Plus is a battery and solar wireless camera with a 5-inch monitor at $129.99. AUTO-VOX lists a two-minute installation with no wiring or drilling, a 52-foot range, 1080p video with night vision, a 5,000 mAh battery lasting three to four months per charge, a 140-degree lens, dual-channel split screen and IP69K waterproofing.

12-inch mirror dash cam with rear camera.
The G840S is a 12-inch mirror dash cam at $169.99 that records the road ahead in 4K and shows a rear camera view in the mirror. WOLFBOX describes automatic parking mode and collision-triggered locking of recordings. It replaces a separate dash cam. The rear camera runs on a cable, so plan for a longer installation.

Wired power, solar or mirror
A camera wired to the reverse lights turns on when you select reverse and never needs charging. Installation means reaching the tail light wiring. The AUTO-VOX W12 works this way: the camera takes power from the reverse lights and the monitor from the cigarette lighter socket or fuse panel. AUTO-VOX describes it as a 30-minute installation.
Battery and solar cameras mount on the license plate with no wiring. AUTO-VOX lists a 5,000 mAh battery lasting three to four months per charge on the Solar3A Plus, with a solar panel to extend it, and describes installation as two minutes. A car parked in a garage gets little solar charge.
A mirror dash cam replaces the view in the rear-view mirror with a screen and records the road as well. It does more, and its rear camera connects by cable, so installation takes longer.
| Kit | Screen | Power | Range listed | Price seen |
|---|---|---|---|---|
| AUTO-VOX Solar3A Plus | 5 in | Battery and solar | 52 ft | $129.99 |
| AUTO-VOX Solar3A Plus Max | 7.2 in | Battery and solar | 52 ft | $159.99 |
| AUTO-VOX W12 | 5 in | Reverse lights | 35 ft | $99.99 |
| eRapta AWTCM702 | 7 in touchscreen | Battery and solar | Not stated | $209.99 |
| WOLFBOX G840S | 12 in mirror | Vehicle power | Wired | $169.99 |
Screen, image and range
A larger screen makes distance easier to judge. Five inches is enough for a car. A 7-inch screen suits a truck or trailer and takes more dashboard space.
All four camera kits list 1080p video and night vision. AUTO-VOX lists a 140-degree lens on the Solar3A Plus models and 135 degrees on the W12. A wider angle shows more to each side and makes objects look farther away.
Wireless range matters for long vehicles. AUTO-VOX lists up to 52 feet for the Solar3A Plus models and 35 feet for the W12. That covers cars and pickups. For a long trailer or RV, check the range against the distance from hitch to cab, and note that metal between camera and monitor reduces it.
Recording, second cameras and weather
Some kits record. The Solar3A Plus Max lists loop recording, and the eRapta includes a 32GB card for loop recording. A basic backup camera only shows a live view.
The Solar3A Plus, the Plus Max and the W12 support a second camera with a split screen. eRapta describes its kit as including two cameras, along with blind spot detection that gives a screen and audio warning.
A camera on the outside of a vehicle faces rain, car washes and road salt. AUTO-VOX lists IP69K on all three of its kits, and an operating range of -4°F to 149°F on the W12. The eRapta's magnetic base does not hold on aluminum, according to its own page.
How these picks were chosen
We chose kits with published specifications that cover wired, solar, magnetic and mirror designs. Three of the five come from AUTO-VOX, which reflects the limits of what we could verify on official pages. Garmin and other brands make backup cameras too. They are not covered here, and that is a limit of this page. In the US, new cars built since May 2018 must have a rear camera, so these kits are for older vehicles and trailers.
