A If user has defined the snapshot interval, Video Server will capture images of four

video inputs 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. User may retrieve these files either by

downloading via FTP or direct Video Server send them in e-mails. That means 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 rather than steady state. For instance, use

‘Rising’ and ‘Falling’ rather than ‘High’ and ‘Low’ to let the condition be triggered only

when state is changed.

Q I have already set the video inputs to different quality but I still see the old quality

setting when I choose Video All.

A Video All is a special feature to be used for quick checking for four cameras at the same

time. Internally four images of video inputs are compressed with the same settings

based on the first video source.

Q I try to connect my black-and-white and color cameras with Video Server but the

image is not good.

A Although Video Server allows users to choose color or black-and-white images for each

camera, hybrid camera types may increase video processing time and reduce system

performance. While connecting multiple cameras, the same modulation type and color

format are recommended.

Q The image is not clear enough. Is anything broken?

A The lens can be fine adjusted by rotating the outer ring. Please rotate it clockwise or

counter-clockwise to focus near or far.
