2.3.7 Tampering
The tampering settings can be found under this path:
System > Tampering
The tempering alarm function protects the IP camera against tampering
– such as deliberate
redirection, blocking, paint spray and lens cover etc. In case of any sabotage action, a
notification or a snapshot is sent to the specified recipient.
Detection of camera tampering is achieved by measuring the differences between the older
frames of video (which are stored in buffers) and more recent frames.
Tampering alarm:
Users are able to turn on/off the tampering alarm function. The default setting is
“Off”.
Tampering duration:
Minimum tampering duration is the time for video analysis to determine whether camera
tampering has occurred. Minimum duration could also be interpreted as defining the
tampering threshold; longer duration represents higher threshold. Settable tampering
duration time range is from 10 to 3600 seconds. The default value is 20 seconds.
