34 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 32), 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 covered
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.
Motion Detection
Motion detection is used to generate an alarm whenever movement either occurs or stops
in the video image. A total of 10 Include and/or Exclude windows can be configured.
• Included windows target specific areas within the whole video image
• Ex
cluded windows define areas within an Include window that should be ignored
(areas outside Include windows are automatically ignored)
