800-18160 - A - 06/2014

Anti-dither Select an anti-dither time, from 5s to 600s. The anti-dither time

starts when a second alarm is detected, and it determines

what happens when a second alarm is detected. It determines

if a second alarm will trigger another alarm action such as

showing a screen alert, sending an email, starting a buzzer,

flashing a light, activating a PTZ tour, taking a snapshot, or

recording video. During the anti-dither time, if the system

detects another alarm, the system will not be activated.

If you set the Anti-dither time for 10 seconds, then each

activated alarm action will last for 10 seconds. But if the alarm

is triggered again 5 seconds after the anti-dither time began,

then alarm actions such as a buzzer, PTZ tour, PTZ activation,

snapshot, and recording will reset and last another 10

seconds from that second alarm trigger time. There will not be

another screen prompt or alarm upload, nor will another email

be sent. After the 10 seconds is over, if the system detects

another alarm after the anti-dither time is over, it will generate

another alarm.

The stay time here does not include the latch time.

Alarm Out Select the device output port, from 1 to 3. Select the

corresponding port(s) so the system can activate the

corresponding alarm devices when an alarm occurs.

Latch When the anti-dither time has ended, the channel alarm you

have selected will last this period. Select from 1s to 300s.

Latch does not work with other alarm activation operations.

Latch is still valid even if you directly disable the alarm event

function. The system can delay the alarm output for a

specified time after an alarm ends. The value ranges from 1s

to 300s.

Show Message Click to enable a pop-up message on your local host PC

screen to let you know an alarm has occurred.

Alarm Upload Click to enable the system to upload the alarm signal to the

network (including an alarm center and the web client). The

system uploads only the alarm channel status.

Go to the Web operation, and then go to the Alarm interface

to set the alarm event and alarm operation. See Enabling and

Disabling Alarms on page 157 and Configuring Alarms on

page 184.

Send Email The system can send an email when an alarm is detected.

When you have enabled the Snapshot function, the system

can also send an image attached to the email. Go to Main

Setting NetworkEmail to configure the email

settings. See Configuring the Email Settings on page 84.

Record Channel Select a recording channel. See How to Record on page 94 for

more about recording.
