Tamper protection
Various options for tamper protection allow you counteract typical attempts to tamper with cameras and video lines. Run a series of tests at different times of the day and night to ensure that the video sensor is operating as intended.
Global change %
You can define the percentage of sensor fields that must register a change simultaneously before generating an alarm. This setting is independent of the sensor fields selected under Select area.
This option allows you to counteract, independently of motion alarms, manipulation of the orientation or location of a camera resulting from turning the camera mounting bracket, for instance.
Scene too bright
Activate this function if tampering associated with exposure to extreme light (for instance, shining a flashlight directly on the objective) should trigger an alarm. The average brightness of the scene provides a basis for recognition.
Scene too dark
Activate this function if tampering associated with covering the objective (for instance, by spraying paint on it) should trigger an alarm. The average brightness of the scene provides a basis for recognition.
Scene too noisy
Activate this function if tampering associated with EMR interference (noisy scene due to strong interference signal in the vicinity of the video lines) should trigger an alarm.
Select area
The areas of the image to be monitored by the video sensor can be selected. The video image is subdivided into 858 square sensor fields. Each of these fields can be activated or deactivated individually. If you wish to exclude particular regions of the camera's field of view from monitoring due to continuous movement (by a tree in the wind, etc.), the relevant fields can be deactivated.
–Click Select area to configure the sensor fields. A new window will open.
–If necessary, click Clear first to clear the current selection (fields marked red).
