12V-24V Bus Truck Trailer Reverse Rear View System 7" TFT LCD Color Car Rear View Monitor +4Pin 18LEDs Waterproof IR Night Vision Reversing Backup Camera with 15M Cable

I installed this in a contractors cube truck. Would of been nice if they sent wiring instructions I used the black as the ground and combined the red and blue wires to a inline fuse that I installed. I believe the blue wire is a switch lead you can hook up to your reverse lights and the screen will come on then. I hooked mine up so it comes on and off with start of truck. For what it's for it's ok. I didn't need anything fancy . Its 7" display works good, camera is good mount for display kinda of thin

got the job done

Good price and worked for me.

Works great day and night

Good: It works.Image quality is OK for it's intended use. You don't need HD resolution to avoid backing up into a tree.Cons: very cheap hardware, fasteners.Screws strip easily. No in instructions or wiring diagrams provided. Durability to be determined.Rule #1 you get what you pay for! You'll have to spend more to get better quality. This does the job for an RV.

You get what you pay for. It works well, but picture is a bit bright. Hard to see while driving wearing sunglasses and with the monitor sitting on the dash, otherwise, fills the need for a rear view camera for my fifth wheel.
