Digital Wi-Fi CCTV system is a lot of using traffic control, preventing accident and taking follow-up measure. Development of Wireless LAN and IP network technology creates new service which applying to fusion technologies such as CCTV, IPTV, and so on. Also, The development of Wireless LAN is very important in Wi-Fi CCTV network field which requires the best quality of service on the security, QoS and bandwidth. In this paper, we introduce various wireless LAN and Wi-Fi CCTV network technology. And then, we construct various experimental network for performance measurement of Wi-Fi CCTV video quality. On constructed experimental network, we measure PSNR which computes the peak signal-to-reconstructed video measurement in experimental network environment, analyze PSNR value. And as a result of measurement, we propose optimum network environment for Wi-Fi CCTV service provider.
