Recording Buffer Settings
Pre-Buffer - Specify the length of the period to record immediately preceding the event.
Configurable in seconds, minutes or hours. Useful for e.g. seeing what happened
immediately before a fire alarm. This setting is optional.
Recording Duration - Specify the length of time to record. Used to specify an exact duration,
this setting can be used to e.g. take snapshots of predictable conditions of a constant
length and which do not vary. Configurable in seconds, minutes or hours. This setting is
optional.
Pan/Tilt/Zoom Control
If a camera uses a Pan/Tilt/Zoom (PTZ) device, it is possible to define which preset position
the device will move to when the event is triggered.
If several events are recording at the same time, the PTZ device will move to the preset
position for the event that has the highest priority. When this event stops recording, the
PTZ device will then assume the preset position for the next active event that has the
highest priority.
Preset positions for each camera are defined under Camera Options.
Output Relay
To display the checkbox for the Output relay in the event settings, it must first be enabled
on the Alarm Settings page. This will enable the checkbox for all events. Once the
checkbox is visible, the output relay can then be enabled or disabled independently for
each event. Once the output relay has been activated by the event, it will remain active as
long as the event is recording.
If the heading for the Output relay is marked as Disabled , click the Alarm Settings button
to go to the alarms page.
