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.
