JPEG Pre Trigger
This menu enables conguration 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 conguration.
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.
Note: It is recommended that the Pre-Alarm option in the ‘Alarm Settings-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. 
Pre-Trigger Duration (secs)  The Pre-Trigger Duration is the maximum possible time that data 
will be stored prior to an event trigger.
