Q. How fast will Video Server check the status of digital inputs?
A. Video Server will check input status in less than half a second. However, to avoid repeatedly
checking conditions too often and to allow the devices connected to digital outputs to function
properly, Video Server will delay 3 seconds by default after each condition matches. Users may
change it according to specific applications. During this period, any condition will be ignored.
Q. Why can I not access Video Server when I setup some options in the application?
A. When Video Server is triggered by events, snapshots will take more time to write them into
memory. If the events occur too often, the system will always be busy storing images. It is
recommended to use sequential mode or external recorder program to record motion pictures if
the event is frequent. If you prefer to retrieve images via FTP, the value could be smaller since
FTP responses quicker than the Web does. Once the system is too busy to configure, use the
restore factory default and reset button to save the system.
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.
