Introduces a wireless video sensor, which is based on wireless sensor networks technique. It can be widely used including battlefield intelligence, security monitoring, and environmental tracking. The Zigbee communication protocols is based on the IEEE 802.15.4-2003 standard. With JPEG compression, the video can be transmitted through the low rate wireless network. Wireless video sensor nodes form mesh networks, and transmit video information to coordinator. The coordinator connects to monitor station, and the monitor software display the video from the nodes in the wireless networks.
