AXIS 223M - Event Configuration
Camera Tampering
The camera tampering application 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 33), in order that the
camera can send an alarm.
Settings
Minimum duration - This parameter 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 - This alarm can go off if the camera lens is sprayed or cov
ered so
that the camera live view becomes dark, as well as when lighting conditions change. The
camera would not distinguish between the two.
When this parameter is enabled, alarms will be generated for
all cases where the lights are
either dimmed or turned off, or if the lens is sprayed, covered, or severely defocused. If not
enabled, no alarm is sent.
After making these settings, click Save.
