Download Event-triggered Snapshots
There are three video image files for the video channel 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.
