The device interface
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.
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.
Video out
Power settings
Power settings
Delayed shutdown: Turn on if you want to set a delay time before the power is turned off.
Delay time: Set a delay time between 1 and 60 minutes.
Accessories
Network speaker pairing
Network speaker pairing allows you to use a compatible Axis network speaker as if it is connected directly to the camera. Once
paired, the speaker acts as an audio out device where you can play audio clips and transmit sound through the camera.
Important
For this feature to work with a video management software (VMS), you must first pair the camera with the network
speaker, then add the camera to your VMS.
Address: Enter host name or IP address to the network speaker.
Username: Enter username.
Password: Enter password for the user.
