Infrared (IR) cameras have a sensor that measures the ambient light. This determines when to switch the camera between color recording and IR / night vision recording. If there is not enough ambient light hitting the sensor, the camera will record in IR / night vision mode. A cooler colored ambient light may also prevent the infrared (IR) cut filter from engaging, which can cause the camera to display in black and white.
Inadequate light or power may cause the camera to record in black and white.

Evaluate the lighting condition. If the camera is in shade or a dark area it may be displaying in night vision mode. Adjust the sun shade and re-position the camera into different or brighter lighting.
The camera may be recording in night vision if it is not receiving enough power. To test the power:
