for details on attaching alarm inputs.

Alarm Inputs:
Alarm inputs are devices or switches that activate when a door, window,
cabinet etc. is opened or accessed. For example, you might want to only
have the camera record when someone opens a tool cabinet or when a door
opens vs. recording when motion occurs around those areas. There may
be people moving by those areas frequently but you are only concerned
about when those areas are accessed. This saves hard drive space and
makes it easier to find an event that was recorded to the hard drive.
Select Alarm in Module:
Alarm Input cables of device of Alarm in: one is connected with "COM" port,
the other is connected with the port "1/2/3/4" (This should be in accordance
with Alarm Input ID 1/2/3/4 in DVR software). The below figure shows the
Alarm Input cable has been connected with Port 1, so the Alarm Input 1
should be set in DVR software.
Alarm Output:
Alarm output is used to activate an external device such as a horn
or light after an alarm is triggered. To do this the DVR uses a dry
contact normally open relay. To configure alarm outputs, connect the
external device to the out connections on the alarm block as required
by the device. The maximum contact rating is 24 VDC @ 3A. Alarm
input can start recording on any one of the camera channels.
