The future of surveillance, no battery required

This Self-Powered Video Camera Can Keep Recording Forever
A new type of video camera is entirely self-powered. Columbia University researchers created this promising technology, it can go on and on without a battery, continuously recording one image per second of “a well-lit indoor scene”.

The camera sports a new kind of power-harvesting image sensor that switches between capturing images and generating power when not in use.

It should come as no surprise that this research was funded by the US Government which might be interested in military use of  self-powered cameras for surveillance.Self-powered cameras could be installed in places like outdoor spaces that don’t have power. The next generation of these cameras may soon be working in our city.

The videos are grainy, but clear enough to get a good idea of what someone’s doing. See more here.
