Swift Hitch SH02D Digital Wireless Backup Camera for RV, Trailer, Truck - HD Rear View Monitor with 8-Hour Battery Life | Perfect for Parking, Hitching & Towing Safety

Giving this item 5 stars. Makes backing up and hitching to my trailer easy. It also serves as a back-up camera that can be attached to the rear window of the trailer via the glass suction cup attachment (I wouldn't travel with it attached to the back of the trailer to use it as a rear view camera, as it may get knocked off if you go over a pothole or big bump on the road, but it is useful for backing into a site when you arrive at your destination).Video quality is good enough for the task at hand. The FOV is narrow, but probably should be when viewing the hitch (which is the primary use of this camera). I haven't experienced any issues with signal, even when the camera is attached on the back of the trailer (about 30+ ft from the drivers seat). I think the set WiFi signal is an excellent solution, and better than bluetooth because you don't have to turn off a bluetooth device that may be in use while using this camera system. The video monitor is small, but effective. Frankly i like the compact size of the monitor as it doesn't take up much space. Comes in a nifty case. A solid product that does exactly what it is suppose to do.
