After analysis video, system can generate a motion detect alarm when the detected moving signal

Figure 3-97.
Event type: From the dropdown list user may select motion detection type.

Region: Click select button, the interface is shown as in Figure 3-98. Here user may set motion
detection zone. There are four zones for you to set. Please select a zone first and then left drag the
mouse to select a zone. The corresponding color zone displays different detection zone. User may
click Fn button to switch between the arm mode and disarm mode. In arm mode, user may click the
direction buttons to move the green rectangle to set the motion detection zone. After you completed

Sensitivity: System supports 6 levels. The sixth level has the highest sensitivity.
Anti-dither: Here user may set anti-dither time. The value ranges from 5 to 600s. The anti-dither time
refers to the alarm signal lasts time. It can be seem as the alarm signal activation stays such as the
buzzer, tour, PTZ activation, snapshot, channel record. The stay time here does not include the latch
time. During the alarm process, the alarm signal can begin an anti-dither time if system detects the
local alarm again. The screen prompt, alarm upload, email and etc will not be activated. For example,
if you set the anti-dither time as 10 second, user may see the each activation may last 10s if the local
alarm is activated. During the process, if system detects another local alarm signal at the fifth
second, the buzzer, tour, PTZ
activation, snapshot, record channel will begin another 10s while the
screen prompt, alarm upload, email will not be activated again. After 10s, if system detects another
alarm signal, it can generate an alarm since the anti-dither time is out.

motion detect period. System only enables motion detect operation in the specified periods. It is not
