About External Alarm Inputs

Each camera can have an external sensor

associated with it (dry contact). If enabled, the

camera-view will be recorded whenever the

sensor is tripped (and if set up, a ‘pre-

recording’ of just before the event will also be

available). This can be instead of, or in

addition to video motion sensing.

Tip: External inputs can also: • Trigger alarm-alerts

and email; • Aim an associated (PTZ) camera to a pre-

defined ‘preset’ position; • Display the camera image

on a TV monitor until acknowledged by someone (TV-

Out / Spot Monitoring). For details, check the index for

a desired keyword.

The sensors can be either normally open, or

normally closed (as long as you 'tell' the Video

Server software which type of sensor you are

using). This is done under:
