as in Figure 4-156. There are four record types: regular, motion detection (MD), Alarm, MD &
alarm.

PTZ activation: When an alarm occurred, system can activate the PTZ operation. The PTZ activation
lasts an anti-dither period. See Figure 4-154.

Anti-dither: 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 buzzer, tour, PTZ
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.

Alarm output: The number here is the device alarm output port. You can select the corresponding
ports(s) so that system can activate the corresponding alarm device(s) when an alarm occurred.

Latch: When the anti-dither time ended, the channel alarm you select in the alarm output may last
the specified period. The value ranges from 1 to 300 seconds. This function is not for other alarm
activation operations. The latch is still valid even you disable the alarm event function directly.

Show message: System can pop up a message to alarm you in the local host screen if you enabled
this function.

Alarm upload: System can upload the alarm signal to the network (including alarm center and the
WEB) if you enabled current function. System only uploads the alarm channel status. You can go
to the WEB and then go to the Alarm interface to set alarm event and alarm operation. Please go
to the Network interface to set alarm center information.

Send email: System can send out the alarm signal via the email to alert you when alarm occurs.
