if the camera housing is black and equips it with this 940nm ir light, the camera will be totally invisible at night, like hidden camera.

We make the camera with 8pcs lights, 4pcs of them are ir lights, the other 4pcs are with warm led lights. When everything is ok, the ir lights works and night vision is black and white; when something is detected moving in front of camera,the warm lights will turn on and night vision changes to colorful immediately
