Camera Tampering
Camera Tampering can generate an alarm whenever the camera is repositioned, or when the lens is covered, spray-painted or severely
defocused. To send an alarm, for example an email, an action rule must be set up.
To configure tampering detection:
1. Go to Detectors > Camera Tampering .
2. Set the Minimum duration , that is, the time that must elapse before an alarm is generated. Increase time to prevent
false alarms for known conditions that affect the image.
3. Select Alarm for dark images if an alarm should be generated if lights are dimmed or turned off, or if the lens is sprayed,
covered, or rendered severely out of focus.
4. Click Save .
To configure the product to send an alarm when tampering occurs:
1. Go to Events > Action Rules .
2. Click Add to set up a new action rule.
3. Enter a Name for the action rule.
4. Under Condition , select Detectors from the Trigger list.
5. Select Tampering from the list of detectors.
6. Optionally, select a schedule and set additional conditions.
7. Select the action. To send an email, select Send Notification and select a Recipient from the list of defined recipients.
Note
The While the rule is active option under Duration cannot be used with camera tampering, since camera tampering does not
have a duration and once it has been triggered it will not automatically return to its untriggered state.
For more information on actions rules, see Events on page 36 .
