Anti-dither: Here you can set anti-dither time. Here you can 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, you
can 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 b uzzer,
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.
