Abstract
Disclosed is a motion detection system for use in entryways or areas wherein a user may wish to monitor activity, comprising a wireless emitter and detector or system thereof. The emitters utilize a plurality of infrared or other media sensors to emit outgoing signals detecting an object blocking a pathway prescribed by an area between the emitter and a predetermined barrier. Reflections of the outgoing signals are received by the detector and an internal processor calculates an action based on the received input. An automatic calibration is conducted to match the physical reflectivity of the area to minimize false alarms, while the direction of a passing object is determined by a calculated reflection strength gradient and/or time-delay in signal reflectivity. The emitters may be programmed to emit certain alerts based on their input or send signals to a base station, which is communicated to via wireless transmission.
