Detectors
Camera tampering
The camera tampering detector generates an alarm when the scene changes, for example because the lens is covered, sprayed
or severely put out of focus, and the time in
Trigger after has passed. The tampering detector only activates when the camera
has not moved for at least 10 seconds. During this period the detector sets up a scene model to use as a comparison to detect
tampering in current images. For the scene model to be set up properly, make sure that the camera is in focus, the lighting
conditions are correct, and the camera doesn’t point at a scene that lacks contours, for example a blank wall. Camera tampering
can be used as a condition to trigger actions.
Trigger after : Enter the minimum time that the tampering conditions must be active before the alarm triggers. This can help
prevent false alarms for known conditions that affect the image.
Trigger on dark images : It is very difficult to generate alarms when the camera lens is sprayed, since it is impossible to distinguish
that event from other situations where the image turns dark in a similar way, for example when the lighting conditions change.
Turn on this parameter to generate alarms for all cases where the image turns dark. When it’s turned off, the device doesn’t
generate any alarm when the image turns dark.
Audio detection
These settings are available for each audio input.
Sound level : Adjust the sound level to a value from 0–100, where 0 is the most sensitive and 100 the least sensitive. Use the
activity indicator as a guide when you set the sound level. When you create events, you can use the sound level as a condition.
You can choose to trigger an action if the sound level rises above, falls below or passes the set value.
