Select Sunday to Saturday from the dropdown list. Be sure to check the box to the left of the period

as working days and Saturday and Sunday as non-working days. Click the Save button when

Anti-dither
This feature sets a delay period before triggering the next alarm, to avoid re-triggering on the same
event for screen prompt, alarm upload, and email notifications. The delay period begins when the
current event has ended, not including the latch time. The value ranges from 5s to 600s. For
example, if you set an anti-dither time of 10 seconds, the activation will last 10seconds when a local
alarm is activated. If another local alarm signal is detected before these 10 seconds have elapsed, the
buzzer, tour, PTZ activation, snapshot, and record channel will be activated for another 10 second
period. However, the screen prompt, alarm upload, and email will not be activated again. After the
10-second anti-dither time has elapsed, a new alarm signal will be generated when another alarm is
detected.
Type
Select the relay type from the dropdown: Normally Open or Normally Closed.
Record Channel
Select the proper channel to record when the alarm occurs. Make sure to also set alarm record in the
schedule screen and select Schedule Record on the Manual Record screen.
Delay
To avoid rerecording the same event, enter the number of seconds to wait after the event has ended
before a new recording can begin. This value ranges from 10s to 300s.
