Firmware User Manual

Enabled or disabled

Each of the 3 motion detection regions can be enabled or disabled

individually. Look at the example: Only the region 1 is enabled while 2

and 3 are disabled. The disabled regions disappear from the video

display.

Note that the number of the motion detection region is written in the

upper left corner of the region.

Location of the region

You can move the motion detection region anywhere on the field of view

by dragging the top of the motion detection rectangle as shown on the

image. The motion detection regions may even be overlapping if you like.

Size of the region

By dragging the lower right corner of the motion detection region you

can change the size of the region. The maximum size of the region can

even be as big as the whole screen.

Sensitivity

Sensitivity is the parameter that helps us distinguish actual moving targets (people, vehicles) from the

slightly moving background, such as leaves of the trees waving in the wind. In order to avoid false alarms,

we might want the camera be able to ignore small motion. The higher is the sensitivity level of the

camera the smaller shift of the object is needed to trigger the alarm. For example, if the object within

motion detection region has moved for about 1-3 pixels during two video frames, then such small motion

will be discarded by camera if the sensitivity is low, and will still trigger an alarm if the sensitivity is high.

In other words, you can think of sensitivity level as a reversed speed limit – the smaller is the sensitivity,

the faster are the objects allowed to move without being detected.

The biggest challenge of motion detection configuration is to find the settings that do not produce false

alarms and at the same time do not miss any

actual intrusions. The rule of thumb is: the

sensitivity should be as high as possible while

not producing false alarms. The default

sensitivity level of the cameras is 70 (on a scale

of 0-100) and works for most standard cases.
