Night Motion Setup

At night time, depending on the camera used, there is generally a lot of video noise generated.

This being so, the value selected for Motion Detection during the day may not be suitable for

night use. The noise generated may trigger the recording permanently. The “Night Motion

Setup” allows for different Motion Detection settings for night use.

Insert Motion Detection (MD) Zone Mode

You can select each camera individually and insert motion detection zones (up to 16 zones) by

clicking on the “Insert Zone” box and drawing in boxed zones. Then, click “Test”. It will

display motion signs as above if there is any motion detected. By Clicking “Insert Entire

Zone” you will select the whole box automatically.

Insert Entire Zone

You can select this should you wish to set the whole area as a motion detection zone.

Clear Zone

This will remove the motion detection zone you created.

Clear Entire Zone

This will clear the entire zone of motion detection.

Note: The sensitivity of Motion Detection depends on the percentage of changed pixels in a

selected Zone. It is very important to understand this concept clearly.

When you insert a small zone in the box, let’s say there are 500 pixels and you set the

sensitivity level as 1 for example. In this case, the unit will detect motion when at least 5 pixels

are different from the previous video frame.

For the same video camera as above, if this time, you insert a smaller zone of, let’s say 100

pixels at the same sensitivity level condition, the unit will detect motion when only 1 pixel is

different from the previous video frame.

Therefore, a smaller MD zone is more sensitive than a larger one at the same sensitivity

setting. If there is more than 1 MD zone in the box, the percentage concept will be used for the

smallest MD zone set up.

For long-range monitoring, objects will appear smaller. Therefore, even with sensitivity level

set at 1, the unit may not detect motion if the entire zone is selected for motion detection. It is

often better to break up the image into two or more smaller detection zones.
