Q: How will the stored images be processed if Video Server loses power?
A: If a user has defined the snapshot interval, Video Server will capture images periodically as
pre-alarm stage. Once the pre-defined condition is match, the pre-alarm images will be kept and
the current images will be saved. The subsequent images will be stored as post-alarm stage.
Users may retrieve these files either by downloading via FTP, or direct Video Server to send
them in e-mails. This means that after monitoring conditions are met, Video Server will keep
these image files until user retrieval even if power is lost.
Q: If I set Video Server to send e-mails of images whenever the conditions are met, will my
e-mail account overflow?
A: It is recommended to use transient state instead of steady state. For instance, use ‘Input is
Rising’ and ‘Input is Falling’ rather than ‘Input is High’ and ‘Input is Low’ to let the condition
be triggered only when state is changed.
Q: The image is not clear enough. Is anything broken?
A: The lens can be focused by rotating the outer ring. Rotate it clockwise or counter-clockwise to
focus near or far.
