Camera Tampering (AXIS 209 FD-R/FD-R M12)

The camera tampering application, which is currently available only for the AXIS 209 FD-R/FD-R M12, generates an alarm whenever the camera is repositioned, or when the lens is covered, sprayed or severely defocused. You must create an event, see How to set up a triggered event, on page 21, for the camera to send an alarm.

Note: Once you have set up camera tampering correctly, if you significantly change the area in front of the camera, i.e., 90% of the area must have been changed, an alarm will be triggered.

For example, if you have set up your Axis camera to monitor a room and you move furniture, pictures, and change the wall paper, so that you have changed nearly the entire appearance of the room, an alarm will be triggered.

The settings available are:

Minimum duration - This sets the minimum tampering period, that is an alarm will not be triggered until this period has lapsed, even if the tampering conditions are otherwise met. This can help prevent false alarms for known conditions that affect the image.

Alarm for dark images - If the camera lens is sprayed and the image is darkened, it will not be possible to distinguish this from other situations where the same effect is seen, that is when the lighting conditions change. When this is enabled, alarms are generated for all cases where the image turns dark or the lens is sprayed.
