When someone viciously masks the lens, or the output video is in one-color due to the environments
light change, the system can alert you to guarantee video continuity. Tampering interface is shown as
in Figure 4-114
. You can enable “Alarm output “or “Show message” function when tampering alarm
occurs.
Sensitivity: The value ranges from 1 to 6. It mainly concerns the brightness. The level 6 has the
higher sensitivity than level 1. The default setup is 3.
Tips:
You can enable preset/tour/pattern activation operation when video loss occurs.
Please refer to chapter 4.7.1.1 motion detection for detailed information.
Note
In Detect interface, copy/paste function is only valid for the same type, which means you cannot
copy a channel setup in video loss mode to tampering mode.
About Default function. 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 tampering interface, you can only restore default tampering setup. It is null for other detect
types.
System only enables tampering function during the period you set here. It is null for motion detect
or video loss type.
