Video surveillance is one of the promising applications of the Internet of Things paradigm. We see heterogeneous deployment of sensor platforms in a multi-tier network architecture as a key enabler for energy optimization of battery powered high-quality video surveillance applications. In this paper, we propose a heterogeneous wireless multimedia sensor network (WMSN) prototype composed of constrained low-power scalar sensor nodes and single board computers (SBCs). Whereas constrained nodes are used for preliminary motion detection, more capable SBCs are used as camera nodes. The camera nodes stream full HD (1080 pixels) video to a remote laptop during occurrence of an event (when motion is detected). We also present a simple power model and simulation results of battery life of the motes for variable event interval and event duration.
