The technologies today for installing the wireless cameras still require a power soruce for wireless cameras.

MicroPower has developed low power consumption technology which requires 1/20th the power of competing technologies for the wireless IP video cameras.  MicroPower Technologies cameras can be smaller, lighter, and greener than any other wireless video technology on the market.
