ALARM
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
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
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.
