6.1
System I/O Primer
Video Servers support video motion
sensing (configurable including detection
zones), plus one physical sensor
associated with each camera. Both
features can trigger automatic recording,
and the system can be set to maintain
short recordings so the view of just before
motion was detected is available (pre-
alarm recording).
Motion detection and/or video/signal-
lost detection can also:
• Trigger an email recipient, or;
• Cause a surveillance station to be alerted to
check a specific camera.
Three outputs are supported at each Video
Server for additional signalling. These can be
used to alert an alarm system, or to trigger a
self-powered device. One output activates
when motion is sensed in any camera view,
another when any external input is triggered,
and the third one activates on either (both) of
these conditions.
Tip: Inputs and outputs are supported through a
special wiring harness.

Alarm Alerts
6.2.1
Introduction / Activate the Alarm
Receiver
A NetVision Video Server can let one remote
station (plus multiple e-mail addresses) know
when an alarm occurs (external input tripped,
video motion-detection, or video-lost). These
are known as ‘Alarm Alerts’. A recording of the
scene will also be available at the Video Server
PC.

'Alarm alerts' are viewed through the "Alarm
Alert Receiver".
To activate the Alarm Alert Receiver, start your
remote software, and click the Alarm Alert icon
(head/portrait) once.
The Alarm Alert Receiver can also be run on its
own:
Startup: Run Alarm Receiver.exe in the folder for
your NetVision software (under C:\Program
Files\Digital Surveillance Recorder\...).
Shutdown: Right-click the Alarm Alert Receiver
symbol (head/portrait) on the right-hand side of the
Windows task bar, and select Exit.
