In order to solve the problem that the target identified by different cameras was discrepant during the process of tracking ,the external synchronization function is developed based on the common camera .Also ,a program is proposed ,taking CXD3172AR ,a microprocessor specially used in DSP and EEPROM as driver ,then using synchronous signal generator and phase locked loop circuit ,to achieve external synchronization .Meanwhile a signal processing circuit is designed to achieve the output of digital format . T he experimental results show that the video surveillance camera had the features of stable output signal ,external synchronization ,image resolution up to 752 × 528 and output frame rate up to 50 frames/s .
