Abstract: A hybrid target tracking wireless multimedia sensor networks has been designed and implemented.The hardware and software of low power wireless image and temperature sensor nodes，as well as the software of the server，have been carried out.The performance of sensor nodes and the network with single sink has been tested.Compared with the Cyclops and MeshEye，the processing speed has been promoted from 8 MHz and 55 MHz to 240 MHz respectively.The current of the processor，which is lower than Imote’s 66 mA@104 MHz，is 52.7 mA@188 MHz.The wireless image sensor can detect the target and send the image data to the server.In order to avoid transmitting the image of the same target and reduce the energy consumption，the wireless image sensor matched the targets by Shape Matching method.The network bandwidth is about 36 kb/s when the data error ratio is 0.The data processing strategy for target tracking based on Shape Matching reduces the energy consumption.
