I recently installed the DVKNM Magnetic Solar Wireless Backup Camera HD1080P with the 7" DVR monitor on my RV, and I’m very impressed. The installation was incredibly easy—it really did take just a few minutes, and the magnetic mount made it simple to position exactly where I needed it without any complicated wiring.

The video quality is clear and sharp, which makes backing up my RV much safer and less stressful. The wireless connection has been reliable, and the solar charging is a great feature since I don’t have to worry about constantly recharging it.

Another highlight was the customer service. They were very responsive and helpful when I had a quick question during setup, which made the whole experience even better. They also sent a metal plate to install the camera.

Overall, this is a great backup camera system—easy to install, works great for RV backing, and backed by excellent customer service. I would definitely recommend it.

I did a lot of research and I bought these with the intent on having rear and side visibility on my 31’ Class C motorhome. Right out of the box they worked. I testing them in my garage and they were (to my surprise) plug and play. Both Cameras synced instantly with the monitor and there was no setup involved at all. I tested them for the first 3 days (one of them on the motorhome) and everything worked like a charm. In testing them, I found that both cameras’ batteries lasted in full sun or partial shade at least 9 - 11 hours with 2 bars left. I found in dual screen mode that both cameras’ images were a bit stretched on the 7” monitor, but still very useful and I got used to it. I didn’t have any problems of the cameras coming out of sync or losing the image while driving. For all you folks that were worried about signal distance. It wasn’t an issue for me at all. In fact, in the picture I posted, you’ll see the Palm trees in the background and that’s where the cameras were. I store my RV about 100 yards from my house and was setting up the monitor in the RV. I turned the monitor on in the RV and to my surprise got a clear picture (as you can see) of my backyard! The camera magnets are “Crazy” strong and I struggle at times getting them off the RV, so no worries about them falling off. There is also a rubber base which keeps the camera from scratching the motorhome or any surface you stick it to.

I now have used them 3 times traveling so far (with Battery life = 9 hours + each day) without any issues. The one thing I did find, that you should use the large antennas on both the cameras and the monitor. I found in using the short ones, the camera’s battery meter didn’t always show up on the monitor. The longer antennas fixed that problem. All in all, the camera quality is excellent and having zero issues with the setup. Charging them are easy and generally recharge them overnight before using them the next day. I am also leaving them on to run the battery down as far as possible before recharging them again. I feel it will help the longevity and I hate short charging rechargeable batteries. Taking a long trip here short and will report back on their performance. Once other thing, I researched that you could conceivably attach a 10W (external) solar panel (with a USB-C plug) to the camera (attached it to the roof) to give you more battery longevity into the evening. So far, I haven’t seen the need since the batteries are holding up during while driving. So far so good and very happy I bought these.

Set up was very easy. The cameras automatically connected to the display as I turned them on. Picture quality is very nice and clear. I purchased this for on the back of a travel trailer. I was a little worried about theft of the camera mounting it to the top of the 4x4 bumper. The magnets are super strong so I mounted one under the trailer to the frame. It is out of sight while still giving a clear view of traffic and obstructions behind me. The picture was upside down but the display has a flip screen feature to correct that. The camera is hard to remove for charging. I am ok with that for the peace of mind that I'm not going to lose it while going down the road. Signal strength is very good. I have about 35ft between display and camera and it shows full signal strength. I think they are a good value for the money. I can't wait to place one camera in a ziplock bag and stick it on my boat trailer.

UPDATE: Upgrading from 4 to 5 stars. Regarding my defective cameras (batteries died in both cameras after 2-to-3 weeks of non-use), I contacted the DVKNM folks via email on Dec 18, 2024 and they shipped me 2 new cameras which arrived 2 weeks and 1 day later (Jan 2, 2025) which, during the Christmas holiday shipping madness may be pretty good. I had to sync the new cameras up to the original monitor using instructions that they sent me and that went smoothly (other than I synced both cameras to the same channel the first time so only one worked, then re-synced the 2 cameras to 2 different channels on the monitor and all was well).

I ordered my first set in early March 2024. I liked it so much that I ordered a second pair (system) in late May 2024 (details later, but wanted to use all 4 cameras on one monitor but that requires syncing the cameras to the different monitor so I haven't done that yet). I loved the easy setup, the great picture quality on the monitor, and the ease of use. I pull several different trailers and I put one of these cameras on the tail gate of my pickup truck to help connect the trailer, and then put the other camera (or both cameras) on the back of the 20' flat bed trailer or the 24' enclosed trailer and can easily see what is behind the trailer. Up until this week I only had 2 complaints (neither of which would stop me from recommending these cameras:

(1) the solar charging is really good IF you had 2-to-3 days to spare waiting for the camera to charge (note the sarcasm!). On the other hand, the USB charging system is reasonably fast.

(2) The windshield mount was really amazing in how good it stuck to the windshield. But only until I had to take it down to move it; then it would no longer stay mounted to the windshield. So, if you need to use the windshield mount then make sure that it is mounted exactly where you want it because if you move it then it will no longer do a good job of holding the camera monitor.

However, this week I took the original purchased set out of my truck and tried to use them. The batteries in both cameras indicated one bar so I plugged the USB into them. After a short time the battery charge indicator showed all 4 lights. But, when I disconnected the USB charging cable, the battery charge indicator went back to showing 1 bar. When I tried to use the camera it would last maybe 3 or 4 minutes and then die. Leaving the cameras on USB charge overnight did nothing to improve the situation and they, like before, showed full charge while the USB was plugged into the camera but immediately went to 1 bar when the USB cable was disconnected.

So, my assumption is that the batteries will no longer take a charge after 9 months of use. The Amazon return window has closed so now I will attempt to see what options I have with the manufacturer's warranty. I will update this review if there is any significant POSITIVE or NEGATIVE feedback with my interaction with the manufacturer.

I haven't used the 2nd camera set yet beyond the initial charge and set up. I bought the second set for the primary purpose of using all 4 cameras on the first monitor, but that didn't work because the two camera systems are on different frequencies, and having only 2 cameras on one system seemed to be giving me all the views that I needed.

This product has worked well for us. Very easy to set up. The Monitor and camera connected immediately and effortlessly. The Battery has lasted well for numerous day trips. We are using it as a horse camera inside our horse trailer. The camera has limited angling so we put it on the inside of the back of the trailer. We can see the whole trailer easily that way. This makes it so the solar panel doesn’t see light but the battery lasts so well that has not been a problem. If we are out for a long time, we stick it to the outside of the trailer to charge but I don’t even think we needed to. FYI, the directions say that the solar charging is limited and can’t be relied upon to fully charge the camera) our trailer is steel so the magnet works well in the trailer. The magnet is strong and no amount of bumpiness has made it budge. If I get the trailer in a pinch and need a back up camera, I could easily reposition the camera to serve that purpose as well. If you have an aluminum trailer, you probably wouldn’t be able to use the magnet aspect. The camera comes with multiple mounting brackets and charging cords that I haven’t needed.

Purchased the AP7-S (7" Magnetic Solar Wireless Backup Camera System) for use behind a 6'x10' trailer pulled by a Toyota Sienna. Solar recharging also works well; I have not had to manually recharge the camera since its initial charging before attaching it to the trailer. The magnet attaching the camera to the trailer is very strong and I can attest that it has not budged a millimeter since its initial placement. The view monitor is attached via the suction cup to the front window of our van and it has not budged either. Picture quality is good; no connectivity or reception issues and good clarity. The camera has been in use now for nearly 6 months and it has exceeded my expectations. It does what you would expect a backup camera to do, but more importantly, it provides a clear view of the road and cars behind when traveling on the interstate, which is the primary reason I purchased it. Additionally, it has performed well in various weather events, including heavy snow and heavy rain. Highly recommend.

Nice picture and strong magnet on camera. Use it on farm equipment. Screen does not stick to glass very well, but that's not a big deal.

Excellent camera. Bought it to assist with backing the trailer into the garage and it makes the job effortless. Strong magnet, clear video, and the solar panel works great. Definitely worth it.

Great products, good quality, and easy installation.

The product itself is great, easy to set up and use. The only issue is that the screen backing melted while it was attached to the windscreen.
