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
59
to configure the alarm inputs.
The network camera has a LAMP setting which allows control of the moving IR cut filter
when there is a change in state from Normally Open to Normally Closed (see
on page
59
for more information). In this way, the moving IR cut filter and the day/night
operation of the camera can be synchronized with external lighting changes using a
common controller such as a photocell or timer.
