Camera Tampering
Camera Tampering can generate an alarm whenever the camera is repositioned, or when the lens is covered, sprayed or severely
defocused. To send an alarm, for example an email, an action rule must be set up.
To congure tampering:
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 congure 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 Notication and select a Recipient from the list of dened 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 46.
Shock Detection
Enable Shock Detection from the Detectors menu. Shock detection is used, for example, to generate an alarm if the product is hit
by an object or if the product is tampered with.
Use the Shock sensitivity slider to adjust the sensitivity level at which the product should send an alarm. Low sensitivity value
implies that the product will generate an alarm only if the hit is powerful. A high sensitivity value implies that the product will
generate an alarm even with mild tampering.
Motion Detection
Motion detection is used to generate an alarm whenever movement starts or stops in the camera view.
Motion detection is congured by dening up to 10 Include and Exclude windows:
• Include windows — dene areas where motion should be detected
• Exclude windows — dene areas within an Include window that should be ignored (areas outside Include windows
are automatically ignored).
