This is the driver code (c++ code) for ptz motor and camera, which uses rs485 and Pelco-D control protocol. Aiming for motor controlling.

Pelco-D is a popular PTZ (Pan / Tilt / Zoom) camera control protocol used in the CCTV industry.

You can directly control the camera or motor through the USB COM port, and send command using the predefined protocol.

Notes

1. Before you can control any Pelco-D cameras, you need to prepare the following items:
   • A PC running 232Analyzer program
   • An RS-232 port (or USB / RS-232 converter)
   • An RS232 / RS485 converter
2. Make sure your COM port settings in the 232Analyzer program matches with camera's settings (Pelco-D cameras use No parity, 8 Data bits and 1 Stop bit, baud rate depends on your camera setting)

The driver class is in:

camera_action.h 
camera_action.cpp

The demo for turn the PTZ camera left, right, up, down is in:

main.cpp
