Motion and Area Monitoring System and Method
First Claim
1. ) A method of detecting motion using a transceiver and a base station, comprising the steps of:
- entering a ground state of beginning motion detection, wherein a first and second signal emitters are activated;
transmitting a first transmission signal from said first emitter and a second transmission signal from said second emitter;
receiving a initial set of return signals, comprising a first and second return signal with a receiver, wherein said signals are reflected from an object in front of at least one of said first or second emitter;
calculating a difference between said first and second return signals against a first and second predetermined threshold signal;
determining whether a foreign object is present based on said difference calculation;
entering another operational state based on said determination of the presence of a foreign object.

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.
