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 David Bowens

I bought this system for my toy truck and was disappointed with the poor signal quality after installation. The distance between the monitor and the camera was only 40 feet, which was well within the car's advertised range of 60 feet. I tried installing the antenna in several different places but the signal kept coming in and out. I contacted the company to explain the problem and they immediately sent me an updated 1080P version with a longer signal range. The updated system worked great with great signal and picture. I give 5 stars for the prompt customer support and will work to resolve the issue without hesitation. I understand that all vehicles are different, but my toy tractor shouldn't be too different from most users' trailers, so I'm deducting 1 star for giving a seemingly unrealistic range. If you have an RV, I would recommend getting the 1080P version.
