Traditional surveillance systems are mainly Closed Circuit Television (CCTV) type; mainly depends on analogue cameras,
heavy wiring and are limited both in coverage distance, video quality and nature of terrain. Hybrid WiMAX-Wi-Fi video
surveillance systems are proposed to mitigate the above constraints as either a complimentary or alternative to the CCTV.
Notwithstanding the cost of WiMAX IP cameras, WiMAX has the advantages of wide coverage, guaranteed quality of services,
high data rate among others. Wi-Fi has the advantage of providing connectivity to a wide range of customer devices, cheaper
Wi-Fi cameras but has limited range. The advantages of WiMAX and Wi-Fi are being exploited to implement hybrid WiMAXWi-
Fi video surveillance systems which can be deployed in developed and developing countries in order to minimise crime in
bus and train station, airports, schools, stadia, organisations and other public places. Performance of such wireless systems are
analysed and compared to the wired.
