Tampering detection

The Server side tampering detection recognizes manipulation of the camera orientation but uses edge detection for comparison. The reference images are generated automatically from every image and compared to the following. Specific tampering events can be used as triggers for an alarm scenario. After an alarm, the reference image will be recreated.

  1. To activate the tampering detection, select Yes from the drop-down-menu.
  2. Click Reset background image to define a new reference image.
  3. To display the actual live image, activate Show live image.

  4. Set the Minimum allowable deviation for the live image (in percent) to specify the threshold value that triggers the motion detection. The higher the value, the less sensitive the image detection will be.

To trigger an alarm, an alarm scenario can be configured for the camera. Or, to configure the event via Ocularis, be sure that the event 'Camera Tampering - Server Based' is selected in the Ocularis Recorder Proxy. Then, in Ocularis Administrator, set an alert for this event on the camera as you would any other event.

  1. Apply the set values if you want to make further settings.
  2. Save the set values to apply the values and conclude input.
