HCD5 equIP Series True Day/Night Network Box Camera Reference Guide
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
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 4-33) to notify the operator.
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
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.
Figure 4-42 D/N Control Message
3. Click OK to accept the changes to configure alarm interlock Day/Night switching.
Now any alarm will be generated and appear on the web client screen.
When Alarm Input is set to Normally Open
When the Alarm Input is set to Normally Open, the camera is normally in Day mode if the
camera alarm input connection is opened.
• The IR-cut filter will be off (removed), and the camera will switch to Night mode if the
camera alarm input connection is closed (shorted). See
23 for more information about alarm connections.
• The IR-cut filter will be on, and the camera will switch to Day mode if the camera alarm
input connect is opened again.
