A burglary-resisting method for building materials and mechanical equipments on the construction site is proposed. An accelerometer detects the acceleration of an object, and a controller analyzes the standard deviation of this acceleration to determine whether a theft event is present. A theft prevention system for multi-object and a wide area is developed by using Zigbee wireless sensor network and GPRS, which is composed of a mobile handheld de-vice, local and remote control centers. The design of hardware and software for the developed system is described in detail. The experimental results show that the designed system can find out a theft event excluding the effects of ac-cidental and periodic disturbance effectively, and the wireless network in data transferring is stable and accurate. This system can easily extend to other application scenario by a slight modification.
