1. A method for wireless power transmission comprising:

  • transmitting, by a transmitter, power waves that converge to form constructive interference at a location associated with a receiver;

    generating, by at least one thermal imaging camera in communication with the transmitter, a thermal image of at least a portion of a transmission field of the transmitter;

    identifying, by the transmitter, a living being in the transmission field of the transmitter based upon temperature data in the thermal image;

    determining, by the transmitter, a proximity of the identified living being to the power waves; and

    adjusting, by the transmitter, a power level of the power waves upon determining that the proximity of the living being is within a predefined distance from the power waves.
