Q. How can I keep Network Camera as private as possible?
A. Network Camera is designed for surveillance purposes and has many flexible interfaces.
The user authentication and special confirmation in installation can keep Network Camera
from unauthorized access. You may also change the HTTP port to non-public number. You
can check the system log to examine any abnormal activities and trace the origins.
Q. I have a PTZ camera that is not on the supported list. How can I control it?
A. Network Camera 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 Network Camera check the status of digital inputs?
A. Network Camera 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, Network Camera 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 Network Camera when I setup some options in the application?
A. When Network Camera 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.
