Rugged Dome Installation Manual Adjusting the Camera

4.4 SETTING THE DAY/NIGHT CAMERA SWITCH LEVEL
The Day/Night Rugged Dome includes a lens that provides a true-color
picture during daylight hours. The camera includes a photocell that
detects when low-light levels occur and, with the removal of a filter from
the lens, instigates infrared (IR) operation. IR operation provides a true
black and white picture during low light conditions.
To set the light level at which the camera switches between daylight and
IR mode, see Figure 15 and perform the following.

non-Day/Night cameras in sections 4.1, 4.2 and 4.3.
