Period
Click the Setup button. The Setup dialog opens. Here you can set the time period when detection is
enabled.
Select Sunday to Saturday from the dropdown list. Be sure to check the box to the left of the period
to enable it. To set your own business day and non-business days, select work day or non-work day
from the dropdown list, and then click the Setup button. For example, you can set Monday to Friday
as working days and Saturday and Sunday as non-working days. Click the Save button when
finished.
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 (NO) or Normally Closed (NC).
