Alarm: Motion Detection Configuration

To set the MOTION DETECTION AREA

In the MOTION DETECTION menu, use the mouse or the arrow buttons to highlight the SETUP button for the channel you wish to setup the MOTION DETECTION AREA for, and confirm by pressing select or left clicking.

•You will see a grid of red boxes. The outlined boxes mark the area that is sensitive to motion. The area without the red outlines is not sensitive to motion.

•Use the mouse to move the cursor around the screen.

•By pressing select or left clicking an area in the grid, you can toggle motion detection ON or OFF in that location.

•Areas marked by red boxes will be sensitive to motion, those not marked will not be.

•Click and drag to select the area you want to select or de- select.

In the sample image above, a person moving about the room would trigger the motion detection. However, a person entering from the right of screen and ascending the staircase should avoid the motion sensitive area. This is a good solution to monitor the door (centre of image) without getting false triggers every time someone ascends the stairs.

Sensitivity: To access the Sensitivity setting, press the right mouse button. The Sensitivity setting is controlled by a slider, allowing you to set a value between 0 and 50. The lower the number, the more sensitive the motion detection will be.

There are four time periods which you can define different motion sensitivity values for.

You can change what time(s) each period starts and ends to best match the changing lighting conditions in your location.

Typically, values between 5 and 10 will give good results in the daytime.

At night, you may get numerous false triggers unless you raise the sensitivity setting, perhaps as high as 25 - 30. This is because when cameras (particularly CMOS-based ones) use active infrared night vision, they dramatically increase the gain controls to the image sensor. This creates a lot of “noise” in the camera’s images, which are interpreted by the DVR as motion.

By default, the day is divided into four periods:

00:00 (Midnight) - 06:00 (6:00 AM)

06:00 (6:00 AM) - 12:00 (Midday)

12:00 (Midday) - 18:00 (6:00 PM)

18:00 (6:00 PM) - 00:00 (Midnight)

You might need to shift the beginning and ends of these times to best suit the time(s) that lighting changes at your location.

The start and end times can be set to anything you like, provided the different time periods don’t overlap and there’s no gap between one ending and the next starting.

There’s no requirement for all four time periods to have different sensitivity levels, although we suggest that usually gives the best performance.

To find the best sensitivity values for different times of day/ night, it’s best to test the system during different time periods.

Get an able-bodied volunteer to move about in front of the cameras you’d like to tune the sensitivity for. The ideal sensitivity level is when your volunteer moving about always triggers the motion detection, but there are no false triggers (or very few) when your volunteer isn’t moving about.
