Local sensitivity

The basic sensitivity of the video sensor 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.

– Adjust the sensitivity by dragging the scroll thumb to the desired setting.

Average (n frames)

You can define the number of frames for which a movement is monitored before

generating an alarm. This helps prevent false alarms from events such as a bird

flying across the surveillance area.

– Select the value by dragging the scroll thumb to the desired position.

Object min size (n*n blocks)

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 2 (2 × 2 sensor fields) is recommended.

– Select the value by dragging the scroll thumb to the desired position.
