Camera tampering
The camera tampering application generates an alarm whenever the camera is repositioned, or when the lens is covered,
sprayed, or severely defocused.
First, you must create an event, see
How to set up a triggered event,
on page 26, for the camera to send an alarm.
Settings
The
Minimum duration
parameter sets the minimum tampering period, that is, an alarm will not be triggered until this period
has elapsed, even if the tampering conditions are otherwise met. This can help prevent false alarms for known conditions that
affect the image.
If the camera lens is sprayed or covered so that the camera live view becomes dark, it will not be possible to distinguish this
situation from other situations where the same effect is seen, such as when lighting conditions change. When the
Alarm for
dark images
parameter is enabled, alarms are generated for all cases where the lights are either dimmed or turned off, or if
the lens is sprayed, covered, or rendered severely out of focus. If not enabled, no alarm is sent.
