I read hands-on reports, including one from a motorhome owner who fitted the camera to his own rig. This AUTO-VOX Solar 5B review draws on their time behind the wheel. I havenāt tested the kit myself.
If you want a rear view without running cable through your RV, the Solar 5B is worth a look. One owner had it in place in under half an hour and could see clearly after dark. Before you buy, check two spots on your rig. You need a sound mount at the rear and space for a powered screen up front.
AUTO-VOX Solar 5B specs, price, and kit contents
The US price was $159.99 for one camera and one screen on November 15, 2026. The page title mentions a 5-inch screen, which can throw you off. Look for the Solar 5B kit with the 7.2-inch screen.
| At a glance | What you get | What to check |
|---|---|---|
| Rear camera | 1080p [full HD video] and infrared [night view] | 90Ā° view from side to side |
| Dash screen | 7.2-inch anti-glare display | Needs a 5V USB power port |
| Camera power | 5,000 mAh [battery capacity] with solar top-ups | How much sun reaches your mount? |
| Mount | Magnetic base, metal plate, and carry case | Does a magnet stick to your chosen spot? |
| Second view | Two views on one screen | The base kit has one camera |
| Recording | Loop recording [new clips replace the oldest] | Supports a microSD [small memory card] up to 64 GB |
AUTO-VOX lists an IP69K rating [dust and high-pressure spray protection] for the rear camera. It also lists 30-day returns and a 12-month warranty. Check the terms if you want the extra six months of cover.
How easy is the Solar 5B to install on an RV?
The quick part is getting the view from the back to the front. The camera sends the picture straight to the screen. You can leave the wall panels in place and skip the long cable run.
- Check the rear surface. Try a magnet where you want the lens to sit. On a fiberglass wall, youāll need a secure metal plate or bracket.
- Check the angle. Look at the screen from your seat before you settle on a spot. Can you see the patch of ground you care about, or does your bike rack fill the frame?
- Check the dash. Find space for the screen and trace the lead to your USB port. The camera runs on its own battery. The screen needs power from the cab.
A van test showed how little work a magnetic fit can take. A motorhome owner chose a more fixed mount. He used his old bike-rack mounts for a bracket and screwed the camera to its plate. Even with that step, he finished in under 30 minutes.

How clear is the picture in daylight and darkness?
Backing from a sunny drive into shade can make detail hard to judge. In the motorhome test, the driver could see detail in both bright and shaded parts of the picture. Once it got dark, the camera switched to infrared. He found the view clear even in complete darkness.
The lens covers 90 degrees from side to side and 50 degrees from top to bottom. Your mounting angle makes a real difference. Point it down for a closer look behind the bumper. Aim it farther back if you want to see more of the approach.
You can adjust the parking lines on the screen. If one angle leaves out a spot you often need, a second camera can share the display. The motorhome test used one camera, so its results cover that setup.
Does the wireless signal hold up on a long vehicle?
The motorhome owner saw no lag or lost picture as he backed into tight spots. Thatās encouraging if you want to watch the gap close as you reverse. The test gives you one rigās result, though. It gives no measured distance for a truck towing a long trailer.
AUTO-VOX lists a 500-foot range in its specs and 524 feet in its sales copy. Treat both as claimed limits. If you tow, check the feed with the trailer hitched and the screen in its usual spot. That tells you more about your setup than a test with both parts on the driveway.
How long does the Solar 5B battery last?
Think about how long you want the screen on. A few short checks at a campsite use less battery than a live rear view on a long drive. You can set the display to sleep after two or four minutes, or leave it on.
AUTO-VOX quotes up to 20 hours of use. It also quotes up to 150 days with typical use, but gives no daily viewing time or amount of sun for that figure. Those 150 days donāt tell you how many hours you can watch the feed.
The motorhome owner found that solar top-ups kept the charge level healthy, even on some dull days. He didnāt run the battery flat and time it. If your RV spends the week under a roof, youāll get less help from the panel there.
Solar 5B pros and cons
| Pros | Cons |
|---|---|
| You can add a rear view without pulling cable through the RV. | A fiberglass rear wall needs a mount for the magnet. |
| One driver got a clear night view and a steady feed on his motorhome. | Thereās no measured range result here for a long trailer. |
| The solar panel helped maintain the charge during real use. | All-day viewing time is still an open question. |
| One screen can record clips and show two angles. | You need dash space, USB power, and a second camera for split view. |
Who should buy the AUTO-VOX Solar 5B?
If you own an older RV and dread pulling another wire through it, this is a good kit to shortlist. Its strongest case is a rig with a sound rear mount, a spare USB port, and a driver who mainly wants help backing into a pitch.
If you want a rear view for a full day on the road, battery life deserves more weight. If you tow a long fifth wheel, signal range comes first. For both buyers, a chance to try the kit on your own rig matters more than the largest number on the box.
Before you order, decide whether you want one view or two. Then check the Solar 5B price and kit contents for the setup you plan to use.
Frequently asked questions
Will it mount on a fiberglass RV?
Yes, with a suitable metal mounting point. The magnet wonāt grip bare fiberglass. The kit lists a metal plate, so check where and how you can fix it to your rig.
Does the dashboard monitor need USB power?
Yes. The monitor plugs into a 5V USB power source. The rear camera has the battery and solar panel.
Can I see two cameras at once?
Yes. With two compatible cameras, the monitor can show both views side by side. Choose the two-camera kit or add a second camera to the base kit.
Does the Solar 5B include a microSD card?
The listing is unclear. Its highlights mention a 32 GB card, but the specs say the card comes separately. The motorhome test covered in this AUTO-VOX Solar 5B review also reported no card in the kit. Check the box contents for your bundle before you buy one.
