Detectors
Camera tampering
The camera tampering detector generates an alarm when the scene changes, for example, when the lens is
covered, sprayed or severely put out of focus, and the time in Trigger delay 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 delay: 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.
Note
For detection of tampering attempts in static and non-crowded scenes.
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.
Shock detection
Shock detector: Turn on to generate an alarm if the device is hit by an object or if it is tampered with.
Sensitivity level: Move the slider to adjust the sensitivity level at which the device should generate an alarm.
A low value means that the device only generates an alarm if the hit is powerful. A high value means that the
device generates an alarm even with mild tampering.
