COM port configuration
Choose serial interface
There are two types of serial interfaces supported by COM port but only one interface can
be used at one time. 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.
COM port configuration
After saving the driver type, the COM port configuration will show up for entering the
correct settings that 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
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.
ISP information setup
In PPP interface, a modem option will show instead of camera control 2. Configurations
include modem initialization and outside dial-up server. If the users will setup with
external sensors and alarms for property security, dial-out is needed to send some
snapshot-attached e-mails when the preset conditions are triggered. In such
