This is the same camera we use in our R22 Robot Chassis kits.
 
This camera has no InfraRed (NoIR) filter installed on the lens, which makes it sensitive to infrared light.  In other words, this camera can take images and video in low-light conditions and when used with infrared LEDs will give you FPV night vision! 
 
Onboard light sensors will detect low-light conditions and automatically turn on the onboard infrared fill LED lights to switch between day mode and night mode.
 
The sensitivity of the light sensors can be adjusted by turning a trimpot with a small screwdriver.
