Two different settings can cause the camera to send back a grayscale image. One setting is called Enable Color. Setting it to FALSE will turn off color. The other setting is called Color Level. Setting it to 0 will turn off color but still returns an RGB image that only contains grays.

The other reason the camera returns gray images is due to low light. In low light situations, the cameras often swap to another mode and boost the signal.
