Q. I have a PTZ camera that is not on the supported list. How can I control it?
A. NetworKam provides a custom camera command interface to control the cameras that are not
supported. The details are described in the manual. Be sure the COM port settings are applied to the
camera specification. The camera control cable included is shown in the package content. Prepare your
own cable if necessary. The general PTZ command is composed of one start command and one stop
command. When editing both commands in the edit box of the configuration page, use comma(s) to
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 NetworKam check the status of digital inputs?
A. NetworKam 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,
NetworKam 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 NetworKam when I setup some options in the application?
A. When NetworKam 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 NetworKam but the image is not good.
A. Although NetworKam 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.
