4.11.3.1.3 Tampering
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 4-110. 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 4.11.3.1.1 motion detection for detailed 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 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.
