or the output video is in one-color due to the environments light change, the system can alert
you to guarantee video continuity. Camera masking interface is shown as in Figure 4-27.

In Detect interface, copy/paste function is only valid for the same type, which means you
can not copy a channel setup in video loss mode to camera masking mode.
Since detection channel and detection type may not be the same, system can only restore
default setup of current detect type. For example, if you click Default button at the camera
masking interface, you can only restore default camera masking setup. It is null for other
detect types.
System only enables camera masking function during the period you set here. It is null for
motion detect or video loss type.
