AUTO-VOX Solar 1 Wireless Backup Camera for Car, 5Mins DIY Installation, Digital Signal License Plate Rearview Camera with 5" Monitor for Trucks/Trailer/RV Review (2026)

Who This Camera Fits

The Solar 1 is built for owners of cars, pickup trucks, cargo vans and smaller RVs who want basic rear visibility added without cutting into the vehicle's wiring. Because it mounts to the license plate rather than requiring a hardwired connection to reverse lights, it suits drivers who want a simple retrofit rather than a full installation project. AUTO-VOX markets it toward medium sized vehicles and small RVs under roughly 33 feet, which makes it a better match for a smaller travel trailer or truck camper than for a long fifth wheel where the wireless signal and monitor size would be more of a stretch.

Display, Signal and Battery Explained

The system pairs a license plate mounted camera with a 5 inch LCD monitor that the manufacturer states delivers a 480p picture at 30 frames per second, enough for basic reversing visibility though modest compared with 1080P systems built for larger rigs. Video travels over a 2.4 GHz digital wireless connection, which AUTO-VOX rates for a stable link up to about 100 feet in open areas, a signal budget that matters more on a long trailer than on a shorter vehicle. The camera offers a 110 degree viewing angle, wide enough to catch cross traffic and obstacles near the bumper rather than only what sits directly behind. Power comes from a 5000mAh battery combined with a solar panel, which AUTO-VOX rates for up to 15 hours of use per charge.

Installing and Living With the Solar 1

Installation is built around a roughly 5 minute DIY process, clipping or mounting the camera to the license plate bracket and pairing it with the monitor, without running wires into the vehicle's electrical system. Because the camera relies on battery and solar power rather than a hardwired connection, owners should position it where it gets reasonable daylight exposure to keep the solar assist working, especially if the vehicle is parked in a garage or under a carport between trips. The 5000mAh battery is meant to bridge gaps in sunlight, but a vehicle stored in shade for extended periods will lean more on that reserve than on solar charging alone.

Trade-offs and How It Compares

The clearest trade-off is scale. A 5 inch monitor and a roughly 100 foot wireless range are enough for a car, pickup or shorter trailer, but they leave less margin than larger 7 inch monitor systems built specifically for long fifth wheels and motorhomes. Owners with a longer rig should compare this against 7 inch monitor kits with a longer rated wireless range before buying, since signal range and screen size both matter more as the distance from tow vehicle to camera increases. The license plate mount is also less flexible than a magnetic or bracket mount, so it fits best on vehicles where the plate position gives a clear rear view. That trade-off between screen size, range and mounting flexibility is worth weighing carefully before buying.

Verdict and Who Should Pick a Bigger System

This camera fits car, truck and smaller RV owners who want an easy, no wiring backup camera and do not need to see much beyond about 100 feet or across a large monitor. Owners of longer trailers, fifth wheels or motorhomes should look at a 7 inch monitor system with a longer rated wireless range instead, since the Solar 1's scale is built for shorter setups. For a straightforward DIY install on a smaller vehicle, the solar assisted battery and quick setup make it a practical, low effort option. Confirming the vehicle length against AUTO-VOX's suggested range before buying helps avoid a mismatch.
