set in “Send pre-event image(s) when event occurs”. The snapshot number and the

snapshots of each channel can also be downloaded via FTP or HTTP URL. Refer to the

live video source. The interval can be set from tenth second to several hours. The
external server must be setup correctly in the Network configuration page.
Sending method
Either event mode or sequential mode can select one method between email and FTP.
The companied external server must be setup correctly in advance. If email is chosen,
the snapshots of selected video channels will be attached in the emails. If FTP is chosen,
administrators can choose to add date and time in the file name of snapshots. If the
snapshots are used as the live video source, the date and time suffix can be eliminated
to update the same source file.
