environments light change, the system can alert you to guarantee video continuity. Camera
masking interface is shown as in Figure 4-23. Here you can enable alarm output or show
message in the screen.
Tips:
You can enable preset/tour/pattern activation operation when video loss occurs.
Please refer to chapter 4.5.2 motion detection for detail ed information.
Note:
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.
