Review on 📷 DOUXURY Wireless Backup Camera System - IP69 Waterproof, 170° Wide View Angle HD 1080P Backup Camera and 7" HD LCD Monitor - Ideal for Truck, Pickup, Trailer, Camper, Bus, RV, and 5th Wheel by Steve Quinn

Excellent reception. 31 foot apartment building. The signal is not lost. However, the return tracks are not precise and not adjustable. Also, the mounting tape came off overnight (all surfaces were wiped down with rubbing alcohol prior to installation) so your only options are to screw it down or use a suction cup - unless you buy some good tape separately. It's nice that the suction cup actually works. this is one of the best suckers i have ever seen. Easy to install except our original rear camera was in the cover and it didn't fit due to the antenna and camera body. I'm only deducting 1 star because the picture is clean and sharp. that's how it works. It was just difficult to install without redesigning the camera body, finding an alternative way to mount the screen, etc.
