Camera Control
Choose serial interface
There are two types of serial interfaces supported by Camera Control. Administrators
must set the correct “Interface mode” between RS232 and RS485 according to the
attached device.
Choose device driver
If the attached device is PTZ driver, administrators should select the appropriate PTZ
model. Refer to our Web site for newly supported PTZ drivers. If the attached PTZ
camera is not in the support list, administrators can select “Custom Camera” to enter
the proprietary commands for pan, tilt, zoom and focus control. If it is not a PTZ camera
but another serial device like video multiplexer, administrators can select the “Generic
CGI command” to control the device via CGI commands. See the URL of External
Device Control section in the Chapter Advanced Function for details.
Port settings
After select the driver type, the correct port settings must be chosen depends on the
camera type. Refer to the Appendix Settings for Supported PTZ Cameras for default
settings of supported PTZ camera including baud rate, data bits, stop bit and parity bit.
Custom commands
Video Server provides five more custom commands other than general pan, tilt, zoom
and preset functions. Administrators can click on “Custom commands” and refer to the
instruction manual of the attached device to setup frequently used functions. The
"Command" should be entered in ASCII format; Video Server will translate it into binary
code and send it out through the serial port. For instance, a text string of "8101ABCDEF"
will be translated into five bytes of hexadecimal 81, 01, AB, CD and EF. The maximal
length of a command string is 60 which is equivalent to 30 hexadecimal bytes. "Display
string" is for text on command buttons and should be less than 8 characters. If the
“Custom Camera” is selected, there will be more commands for PTZF regarding to the
custom camera.
