9.10. Tampering
The Tampering Alarm function helps the IP Camera against tampering such as deliberate redirection, blocking,
spray paint, lens covering, etc. through video analysis and reaction to such events by sending out notifications or
uploading snapshots to the specified destination(s).
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.
NOTE: The Tampering function menu is not available in the camera model GCI-H0503B.
Tampering Alarm :
You will be able to turn the Tampering Alarm function on/off in the Tampering Alarm setting section. The default
setting is: Off.
Tampering Duration :
The Minimum Tampering Duration is the time the video analysis will need to determine whether any camera
tampering has occurred. Defining the Minimum Duration can also be interpreted as defining the Tampering
threshold; longer duration represents a higher threshold. The settable Tampering Duration time range is from 10
to 3600 seconds.
Triggered Action (Multi-option) :
The Administrator can specify alarm actions that will take place when tampering is detected. All options are
listed as follows:
- Enable Alarm Output:
Check this item and select the predefined type of alarm output to enable alarm relay output when tampering is
detected.
- Record stream to SD Card:
When you check this item, the alarm-triggered recording will be stored on your Micro SD/SDHC card when
Tampering is detected.
NOTE: Please make sure the local recording (with Micro SD/ SDHC card) is activated so that this function can be
implemented. See section 9.12. Recording for further details.
