5.23.4Sensitivity (MOTION+ only)

The basic sensitivity of the motion detector can be adjusted for the environmental conditions to which the camera is subject.

The sensor reacts to variations in the brightness of the video image. The darker the observation area, the higher the value that must be selected.

5.23.5Minimum object size (MOTION+ only)

You can specify the number of sensor fields that a moving object must cover to generate an alarm. This is to prevent objects that are too small from triggering an alarm.

A minimum value of 4 is recommended. This value corresponds to four sensor fields.

5.23.6Select area (MOTION+ only)

The areas of the image to be monitored by the motion detector can be selected. The video image is subdivided into 858 square 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.

1.Click Select area to configure the sensor fields. A new window will open.

2.If necessary, click Clear all first to clear the current selection (fields marked yellow).

3.Left-click the fields to be activated. Activated fields are marked yellow.

4.If necessary, click Select all to select the entire video frame for monitoring.

5.Right-click any fields you wish to deactivate.

6.Click OK to save the configuration.

7.Click the close button X in the window title bar to close the window without saving the changes.

5.23.7Tamper Detection

You can reveal the tampering of cameras and video cables by means of various options. Run a series of tests at different times of the day and night to ensure that the video sensor is operating as intended.

NOTICE!

i

The options for tamper detection can only be set for fixed cameras. Dome cameras or other

 

 

motorized cameras cannot be protected in this manner as the movement of the camera itself

 

causes changes in the video image that are too great.

 

 

5.23.8Sensitivity

i

NOTICE!

This and the following parameter are only accessible if the reference check is activated.

 

 

 

 

The basic sensitivity of the tamper detection can be adjusted for the environmental conditions

 

to which the camera is subject.

 

The algorithm reacts to the differences between the reference image and the current video

 

image. The darker the observation area, the higher the value that must be selected.
