Review on AMTIFO A7 HD 1080P Digital Wireless Backup Camera: 2021 Newest Version with 7 Inch DVR Monitor - High-Speed Rear View Observation System for RVs, Trucks, Trailers & 5th Wheels - Stable Signals & IR Night Vision by Brian Sage

For the price the system works very well. I installed it on my 30ft trailer. I have used it several times and have no complaints although I have a few comments. In rare cases, the signal disappears, but is immediately restored. First I connected the camera to the running lights of my caravan with butt connectors. Because the wires to the camera are so thin I couldn't put them in the butt connector so I soldered the connections. When the system is connected to the chases, I use it all the time. This is very useful when changing lanes and of course when reversing. For the price, ease of installation and performance, I'm very happy with the system. Finally, the customer support was the best I've ever encountered. I had a few questions and they were answered immediately via email. Also, when connecting, one of the antennas (there are two of them in the system) did not stay in the upper position, I installed it on the monitor. The system still worked (I taped it over to keep the antenna upright). I contacted customer service and they immediately sent me two replacement antennas.
