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.
