Download Event-triggered Snapshots
There are twelve video image files for four video channels of three stages: pre-alarm, the
moment when triggered and post-alarm. Only the snapshots captured by the last event
are preserved. Administrator and users can use FTP or URL to get the saved snapshots.
They can also be browsed from the application page in system configuration.
