Configuring the Motion Detection Properties

The S1800e encoders support motion detection on each video input. For each

video input, you can configure the motion detection settings by adjusting the

values for each input.

Caution

You must have a good understanding of video technology to use these

settings. If you are unsure do not modify these settings.

► To configure the motion detection properties

1. Start the Web Interface.

2. From the tree, select Configuration >Video.

3. From the Motion Detection tab, you can set the values of the following

parameters for each video input:

State: Enable or disable motion detection on the video input.

Mask State:Enable or disable the use of the mask for motion detection.

If disabled, all macroblocks in the frame are checked for motion.

Mask:Type the numerical string to specify which macroblocks that will

be analyzed for motion. An empty string indicates that all macroblocks in

the frame is checked.

Upper Thresh:The minimum number of macroblocks with motion in a

frame to start an alert. This value must be greater than or equal to

Lower Thresh. The values range from 1 to 1320 (NTSC) or 1 to 1548
