I purchased a Revo Camera System from Sam's Club. When I first installed it everything was good. Now 6 of the 8 cameras will only record in black and white. Once in a while I can get them to turn to color if I move the camera, but then it goes back to black and white.

This is because there is not enough light where the camera is placed and the infrared kicks in. Try providing a light source or moving the camera to an area with enough light.

No Sweat. Try this and post later... Look at the camera directly ther you will se the lens in the middle and several diodes (transparent domes) and you will also find a sensor which is the same size as the diodes but it is not transparent but red looking. Make sure this photo sensor is not being blocked by any dust debris inside or outside the glass, if it is clean it. Please write back No Sweat. Try this and post later...
