In order to meet people＇ s demand for intelligent security system with the constant development of wireless communication technology, a security monitoring system is designed and implemented with contraction technologies of Ad hoc wireless object-monito- ring, which uses Zigbee, RFID and WIFI and other technologies to finish the integration of the wireless network sensor, electronic tag, camera etc. and establish the network system for transmission of environmental parameters, position information and video infonnation. It adopts CC2530 as the core and RFID technology to design Zigbee terminal node, applies the star network to realize the Zigbee wireless networking, the functions of which involves establishment of the coordinator network, connections of terminal nodes and disconnection of the established network,and takes STM32 as the core to design the wireless video monitoring module. The status of system operation shows that it has achieved a shorter networking time, a longer wireless communication distance and a faster wireless transmission rate of video compared with traditional object monitoring system, which can efficiently and quickly collect various types of data with fine ex- pandability and convenient maintainability to meet requirements on security of intelligent systems in different fields.
