This page is used to configure the way that the Uniplex will respond to triggers from a variety of
sources. These triggers include:
•
Activity Detection events
•
Video Motion Detection events
•
Physical Alarm Input activation
–
local alarm inputs on the Uniplex and remote (modbus)
alarm inputs
•
Camera Failure
With the exception of camera failure, if these triggers are momentary they can be extended in their
active period by a number of seconds so that any response by the Uniplex can immediately take
action to capture the event in detail.
The Alarm Expression Wizard page also determines what actions are taken by the Uniplex in
response to the activation of the triggers described above. The actions which can be taken by the
Uniplex include:
•
Changing the recording profile used while the trigger is active so that, for example, the
Uniplex records in high quality while the trigger is active
•
Creating a database entry such that the event appears in the history logs of the Uniplex,
allowing the logs to be searched by event so that video recordings associated with the
event can be found quickly.
•
Reporting the event to a remote video receiving centre RVRC*
•
Sending a PTZ camera to a specific preset position*
•
Operating a relay output (local to the Uniplex or remotely, on a modbus module)*
•
Playing an audio file through the audio output of the Uniplex*
•
Protecting a period of recording of a specific camera for a number of days*
•
Running a PowerScript program located on the Uniplex
* Depending on software version of the Uniplex
