Review on Marine Grade Waterproof Front Rear Camera - Universal Mount with Distance Scale Lines - Backup Parking/Reverse Assist Cam with Night Vision LED Lights - 420 TVL Resolution & RCA Output - Pyle PLCM37FRV by Andre Tenk

Pyle PLCM37FRV Universal Mount Optional Front and Rear View CMD Rear View Camera with Integrated Distance Scale Provides no front view. There are 3 wires (red, white and blue) used to set up the camera; After connecting the blue and/or white wire to the red wire, set up the camera as follows: Connect the blue wire for the mirror image (rear view) and the white wire for the spacer grid. The default "forward view" is achieved by leaving the 3 wires unconnected or connecting the red and white with a spacer grid for the forward view. It would be helpful if the camera worked as described in the instructions, but it only works in the following configuration: the camera does not work at all when the red and blue wires are not connected, ie it only works in the mirror (rear view). You can connect all 3 together to get a specular (rear) view with a distance grid.
