A relational tracking and recording method and apparatus can include: transmitting a signal from a beacon; detecting the signal with a first antenna and with a second antenna, the first antenna coupled to a tracking and recording element; determining a time of flight for the signal between the beacon and the first antenna; calculating a distance between the beacon and the first antenna based on the time of flight; determining a horizontal angle of the beacon; determining a vertical angle of the beacon; positioning an image sensor to face toward the beacon based on the vertical angle and based on the horizontal angle; focusing optics in front of the image sensor based on the distance; zooming the optics in front of the image sensor based on the distance; and recording an image with the image sensor. |
