This paper presents the design method of pan-camera decoder applying in digital video monitoring system including software and hardware. This decoder was based on embedded microcontroller C8051F330 and was mainly composed of regulated power supply circuit, serial communication interface circuit, watching dog circuit, input/output alarm circuit and pan-camera control circuit. It is connected with the UP computer by RS-485 serial communication protocols. This decoder can realizes the pan-camera automatic control, including pan's up, down, left, right, level rotation movement and camera's focus, zoom, iris adjustment. Experimental results show that this decoder operates reliability and accurately.
