Smart cameras are embedded systems that perform on-board video content analysis and only report detected events instead of permanently streaming videos. Visual sensor networks aim at integrating smart cameras with wireless sensor networks. Camera sensors have higher requirements regarding computing power and communication bandwidth than those typically used in wireless sensor network applications. Consequently, power management is an even more critical issue. This work in progress presents an attempt to address this by combining high and low power radios as well as high and low performance computing systems in one single platform. This allows to control power consumption by selectively enabling only required components.
