MicroPower Technologies is a startup aimed at eliminating power wiring for wireless video surveillance cameras through radical reduction of power consumption for the wireless camera. Their first two planned product offerings include (1) a small form factor solar wireless camera that integrates solar panels and batteries into an outdoor fix camera housing and (2) a wearable camera, completely battery operated for short term operation. For the solar wireless camera, they anticipate pricing of $1500 each and $1600 for the base station (supporting up to a maximum of 16 cameras).They project maximum throughput of 35-40 Mb/s and 1 mile transmission line of site using moderately high gain antennas.
The key enabling technology is to reduce the total power consumption of the camera/wireless transmistter. As the video below shows, they report power consumption of a few hundred milliWatts compared to traditional systems of 3 - 5 Watts.
