11. Motion Detection Settings

Say you’re monitoring your yard, and right next to the gate you want to

watch there’s a tree blowing in the wind, which constantly triggers the

motion detection. Perhaps you’re watching a hallway, and your pet cat

continually sets off the motion detection, and you only want to record

humans. What can you do?

You can fine tune your MOTION DETECTION settings to only trigger

the wireless DVR to record when it should! There are several settings

you can configure, and we’ll go through them one at a time. But first,

we’ll examine how motion detection works.

If you’re using motion detection and PIP mode at the same time, the

wireless DVR will automatically change the primary camera being

displayed/recorded if it detects motion on the camera not currently

selected.

How Motion Detection Works

Motion detection is a process undertaken by the wireless DVR based

solely on the image it receives from the camera. There are no external

sensors to connect, nor does the camera send a signal to the wireless

DVR telling it to record -the wireless DVR ‘watches’ the image from the

camera, and detects differences between frames. A frame is one still

image -if you play them quickly enough, one after another, it gives the

illusion of full motion. A single frame is displayed for between 1/25th

and 1/30th of a second.

This means that when the wireless DVR is looking for ‘Motion’ what it’s

really looking for is a change in the picture, specifically, counting how

many pixels (the individual dots that make up an image) change from

one frame to the next. This includes pixels changing colour, brightness

or any combination of the two.

Thus, something does not necessarily have to ‘move’ in frame for the

wireless DVR to detect ‘motion’. For example, sudden changes in
