DOPPLER RADAR MOTION DETECTOR FOR AN OUTDOOR LIGHT FIXTURE
First Claim
1. A motion detector system for monitoring motion within a monitored area, comprising:
- an outdoor light fixture comprising one or more lamps;
a Doppler radar sensor electrically coupled to the light fixture, wherein the sensor emits a first signal to a monitored area and receives a second signal from the monitored area; and
a microprocessor electrically coupled to the Doppler radar sensor, the microprocessor receiving and analyzing the second signal to determine whether a Doppler alarm condition exists.

Abstract
A motion detector system includes the ability to detect motion through the use of a Doppler radar sensor or a combination of PIR sensors and a Doppler radar sensor. The system includes an outdoor light fixture having one or more lamps and a housing coupled to the outdoor light fixture. The housing includes a Doppler radar sensor and a microprocessor for analyzing the signals received by the Doppler radar sensor. Alternatively, the housing includes a combination of PIR sensors and a Doppler radar sensor and a microprocessor for analyzing the signals received from these sensors. The lamps in the light fixture are activated when either the PIR sensor or the Doppler radar sensor generates a signal indicating motion within the monitored area. Alternatively, the lamps can be activated when either the PIR sensor or the Doppler radar sensor senses predetermined number of motion activities over a limited time period.
