Installation Guide
JPEG Pre Trigger
This menu enables configuration of the pre trigger feature (for cameras recording JPEG mode only).
When enabled, the pre-trigger feature will buffer and store alarm recording prior to an event trigger.
Channel
Only those camera channels set to record in JPEG mode will be
available for configuration.
Pre-Trigger (JPEG)
Enabling the Pre-Trigger feature will buffer and store alarm recording
prior to an event trigger (in JPEG format). It will use the maximum
available memory dependent on other cameras requirements of the
buffer space. Select ‘Enable’ to activate.
Pre-Trigger Duration (secs)
The Pre-Trigger Duration is the length of recording prior to an event
trigger that will be saved with the event recording.
Note: It is recommended that the ‘Pre-Alarm sec’ option in the ‘Alarm->Zone Input’ menu be set to the
same value as the Pre-Trigger setting. This will ensure successful playback of high quality Pre-
Trigger images. High quality pre-trigger images will only playback properly if review (playback)
starts prior to the pre-trigger initiation.
