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. To achieve this, create a Camera events report filtered on the Camera tampering event and save it as a public task. Then create a scheduled task to email the Camera events report to the maintenance team following their
schedule.
