Connecting Alarms
WARNING! Do not exceed the maximum rating of 12 V DC, 0.5 A on alarm
output connections.
The network camera has one alarm input and one alarm output available to connect to
peripheral devices (
Figure 2-4 ).
Figure 2-4 Alarm Connections
Connect mechanical or electrical switches to the alarm input connection to allow
event-triggered recording. When alarm inputs are configured, the camera triggers an alarm
only when the normal state (open or closed) changes (see
Figure 2-5 ). See Alarm Settings
on page 81 to configure the alarm inputs.
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
Alarm Interlock Day/Night Switching
on page 81 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.
Figure 2-5 Normal Alarm States
Connect external devices such as sirens or flashing lights to the alarm output connector to
signal users of the camera that an alarm is activated. See
Figure 2-6 for alarm connection.
