Alarm Settings
Connect external devices such as sirens or flashing lights to the alarm output connector to
signal camera users that an alarm is activated. Set the
Alarm Output as Normally Open or
Normally Close . See Connecting Alarms on page 21 for more information.
When alarm inputs are connected, the camera triggers an alarm only when the normal state
(open or closed) changes. An alarm message appears on the web client screen (see
Figure 4-36 ) to notify the operator.
Alarm Interlock Day/Night Switching
The network camera has a D/N Control setting which allows control of the moving IR cut
filter when there is a change in state from Normally Open to Normally Closed or from
Normally Closed to Normally Open for Alarm input (see
Connecting Alarms on page 21 for
more information). In this way, the moving IR cut filter and the day/night operation of the
camera can be interlocked with external lighting changes using a common controller such
as a photocell or timer.
Configuring Alarm Interlock Day/Night Switching:
1. Select Night Mode On Alarm in the D/N Control field in the Alarm Settings pane of
the IO & Audio tab.
2. Click Apply . A message appears.
