For auto iris lenses, use an insulated adjustment tool to adjust the DC
level with the blue pot on the PC assembly (Figure 14). Proper
adjustment will ensure the correct exposure depending on the camera’s
situation and the lighting levels.
To set the light level at which the camera switches between daylight and
IR mode, see Figure 14 and perform the following.
• For brighter light conditions, turn the DC auto iris level adjustment
pot counterclockwise.
• For lower light conditions, turn the DC auto iris level adjustment pot
clockwise.
