In Security Center, camera integrity monitoring is software that detects any form of tampering with the camera, such as moving the camera, obstructing the camera view, changing the camera focus, and so on. The software automatically generates events to alert the security team to remedy the situation.

By enabling the KiwiVision™ Camera Integrity Monitor module, you can ensure that your cameras are operational and effective through periodic validations, and notify your maintenance crew when a camera has been tampered with. This is especially useful for large systems with hundreds or thousands of cameras that make it impractical to manually check the image and field of view of each camera.

Camera Integrity Monitor role

The Camera Integrity Monitor role samples video images from cameras at regular intervals, detects abnormal variations that indicate that cameras might have been tampered with, and generates Camera tampering events.
The role detects several types of dysfunction:
  • Obstruction of camera view (partial or complete)
  • Blurred image (due to change of camera focus or smeared lens)
  • Abrupt change in the position of the camera (due to environmental or human causes)

The Camera Integrity Monitor role can distribute its workload over multiple servers. This should not be confused with failover, where only one server bears the full load of the role at all times.

How to use this feature

Operators can monitor Camera tampering events with the Monitoring task in Security Desk. You can also create event-to-actions to trigger alarms or send emails and messages to the maintenance team when the Camera tampering event is raised.

IMPORTANT: The Camera tampering event is only triggered once when a sudden change to the camera field of view is detected. No other warning is issued. The operator must check the camera view to confirm the issue before sending someone to fix it. After the problem is fixed, the maintenance technician must reset the camera integrity monitoring feature on the camera.

For large systems where the physical maintenance is performed according to fixed schedules, you can automate the generation of the maintenance report for your integrity-monitored cameras and the emails of the report to your maintenance team. Then create a scheduled task to email the Camera events report to the maintenance team following their schedule.
