separate commands. Each comma represents 200 milliseconds. If the user has some serial control device

other than the PTZ camera, the special URL is provided to send the desired commands. For quick access,

integrate the URL to another homepage on your own web server.

Q. How fast will Video Server check the status of digital inputs?

A. The 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,

the 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 the Video Server when I setup some options in the application?

A. When the 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 the Video Server but the image is not

good.

A. Although the 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.
