4.1.11. Motion Detection
Select “VMD” label on the right for users to start the camera’s video motion detection. If the camera is
installed at the places like corridor, door or windows, the image pictures are normally static relatively. Once the
camera detects any object in movement in the video, it shall start recording or generate alarm linkage or output.
The video area on the left is the video motion detection area. Users can use their mouse to draw up at most
five areas in the video area to be the targeted motion detection areas. When detecting any element in motion in
the video, the corresponding associated alarm linkage shall be triggered. If it is required to redraw the areas for
detection, users can click “Clear areas” button on the right.
Fig. 30.
On the right are the settings for the motion detection for defending and the alarm linkage.
Motion threshold:
The default value is 1 (The range of the value is 0 - 100). The motion threshold value is
for measuring the ratio of objects in motion in the selected areas. Smaller the value is, smaller the ratio of
objects in motion is.
Sensitivity:
The default value is 3 (The range of the value is 0-5). The sensitivity is used for evaluating the
level of sensitivity of motion detection. Larger the value is, higher the sensitivity is. Even small motions can be
detected.
Note:
A very low sensitivity may cause failure to report (No alarm when there is any object in motion in the video).
A very high sensitivity may cause false alarms (Any subtle motion like leaf or mice may trigger alarm.) The motion
threshold and sensitivity need to be adjusted in an actual application according to user environment. If the values
cannot be ensured, please keep the default values or increase the sensitivity.
