Is the night vision on the OSI 4K Wi-Fi IP NVR Security System color or black and white?

The night vision on these cameras are black & white, and they also have IR (infrared) sensors to allow to see in complete darkness up to 65'.

If there's enough surrounding lighting from buildings or street lights in the area, the camera may remain in color mode.

Depending on the application, we recommend installing motion lighting if possible. Lighting will help the camera record in color mode and provide more detail. Motion lights also act as a deterrent when triggered.
