Zoom tracing is the process of maintaining auto focus as the zoom lens moves in or out.

Day/Night Mode
The IP Dome provides a black-and-white (B/W) mode to improve camera performance when the
light level falls below certain thresholds. This allows clear images to be obtained under low-light
conditions. This is referred to as IR Mode. There are five IR Mode settings: Off, nM On, nM Auto
High, nM Auto Mid, and nM Auto Low. nM stands for nano meters.
The table below lists the approximate lux values when the camera is expected to switch between
color and B/W modes. Actual values depend on the current zoom setting of the camera and the
light source.

Procedure 4-45 Configuring the IR Mode setting
Switching to black-and-white (B/W) mode when the light level falls below certain thresholds allows
clear images to be obtained under low-light conditions.
