Fixing Camera to Color Video Mode

the ALARM SETTINGS screen.
Depending on the [POLARITY] setting, the camera will be switched between the color and black-and-
white video modes as follows (commonly applied to CAM1 and CAM2):
If [POLARITY] is set to “NO”: Color mode when open; Black-and-white mode when closed
If [POLARITY] is set to “NC”: Color mode when closed; Black-and-white mode when open
If you set [EXT ALARM] to “ALARM IN1” or “ALARM IN2”, the corresponding alarm input terminal will
serve dedicatedly as a Day/Night switching terminal, so you can see only the item [POLARITY] on
the ALARM SETTINGS screen.

Fixing Camera to Black-and-White Video Mode
