Guide to Connect PTZ Camera
I. Something you should know first
1. There are two types of RS-232 ports at a computer, serial ports and parallel ports. The serial
port, so called COM port, is the one for plugging in the control cable from the PTZ camera.
2. PTZ cameras have a RS-422/485 port to plug in the control cable. In order to connect a
control cable from a PTZ camera to a computer, a converter device from RS-422/485 to RS-
232 is usually adopted.
PS: The connection length of RS232 cable is limited in 15 meters. The connection length of
RS-422/485 cable can up to 1,200 meters.
3. A serial port at a computer can control multiple PTZ cameras. These PTZ cameras connected
to the same computer serial port are each identified by a unique hardware ID. You can assign
an ID to a PTZ camera by adjusting the ID switch of PTZ camera device. Detail please refers
to the PTZ camera manual.
