Motion Detection Settings

You can configure the camera’s motion detection.

You can specify when images from the camera are transferred, when alerts are generated and when external outputs (the switching on of the lights or the sounding of a siren) are triggered.

CAUTION

•Motion detection is a key element in system operation, and time spent on finding the best possible motion detection settings for each camera may help you later avoid unnecessary alerts. Depending on the physical location of the camera, it may be necessary to test and adjust the motion detection settings under different physical conditions (day/night, windy/calm weather, etc.).

1 Select the required camera from the [Camera Record Setting] window in the [Device Manager] section and click the [Motion Detection] button in the [Camera Settings] window to open the [Adjust Motion Detection] window.

2 Adjust the sensitivity and threshold value.

•The [Noise Sensitivity] slider determines how much each pixel must change before it is regarded as motion. With a high noise sensitivity, very little change in a pixel is required before it is regarded as motion. Areas in which motion is detected when compared with the previous image are highlighted (by default, in green).

•The [Motion Sensitivity] slider determines how many pixels must change in the image before it is regarded as motion. When the slider is moved from side to side, the black vertical line below the image moves and the threshold is adjusted. When detected motion is above the selected sensitivity level, the bar changes color from green to red, indicating a positive detection.

3 Define the areas in which motion detection is disabled.

CAUTION

•Before adjusting motion detection, it is recommended that you specify image resolution and compression-related settings and define the motion detection exclusion areas. Otherwise, if you adjust the image quality or define the exclusion areas later, it may be necessary to readjust the sensitivity according to the motion detection settings.

Defining Exclusion Regions

Disabling motion in specific areas of a camera’s images may help avoid detection of irrelevant motion, for example if the camera covers an area where a tree is swaying in the wind or where cars regularly pass by in the background.

1 Select the required camera in the [Camera Record Setting] window’s [Device Manager] section, then click [Exclude Regions] in the [Camera Settings] window.

When the [Show grid] check box is selected, the preview image is divided into small sections by a grid. Areas highlighted in blue indicate the exclusion areas.
