Motion detector (MOTION+ only)
For the detector to function, the following conditions must be met:
–Analysis must be activated.
–At least one sensor field must be activated.
–The individual parameters must be configured to suit the operating environment and the desired responses.
–The sensitivity must be set to a value greater than zero.
CAUTION!
Reflections of light (off glass surfaces, etc.), switching lights on or off or changes in the light level caused by cloud movement on a sunny day can trigger unintended responses from the motion detector and generate false alarms. Run a series of tests at different times of the day and night to ensure that the video sensor is operating as intended.
For indoor surveillance, ensure constant lighting of the areas during the day and at night.
Sensitivity (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.
Minimum 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.
Debounce time 1 s (MOTION+ only)
The debounce time is intended to prevent very brief alarm events from triggering individual alarms. If the Debounce time 1 s option is activated, an alarm event must last at least one second to trigger an alarm.
Select Area (MOTION+ only)
The areas of the image to be monitored by the motion detector can be selected. The video image is subdivided into 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.
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.
4.If necessary, click Select All to select the entire video frame for monitoring.
5.
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.
Global change
You can set how large the global change in the video image must be for an alarm to be triggered. This setting is independent of the sensor fields selected under Select Area. Set a high value if fewer sensor fields need to change to trigger an alarm. With a low value, it is necessary for changes to occur simultaneously in a large number of sensor fields to trigger an alarm.
