Abstract
An object detection system for use in residential or commercial buildings includes a housing for retaining a camera, a radar antenna, and an actuator. The camera has a first field of view, and the radar antenna has a second field of view. The actuator is configured to selectively move the camera. The system further includes computer memory and a processor in data communication with the camera, the radar antenna, the actuator, and the computer memory. The processor, using programming contained in the computer memory, causes the camera to move based on camera position data and data from the radar antenna.
Claims13
A security system for use with a residential or commercial building to detect people, the security system comprising:
- a stationary housing;
- a camera contained in the housing, the camera having a first field of view inside or outside the building, wherein the first field of view comprises an azimuth field of view and an elevation field of view, wherein the azimuth field of view is greater than the elevation field of view;
- a radar module vertically aligned with the camera, the radar module having radar antennas contained in the housing, the radar antennas having a second field of view and arranged in a formation including three radar transmission antennas of the radar antennas and four radar receiving antennas around each of the three radar transmission antennas;
- an actuator configured to selectively move the camera;
- computer memory;
- and
- a processor in data communication with the camera, the radar antenna, the actuator, and the computer memory;
- wherein the processor, using programming contained in the computer memory, causes the actuator to move the camera based on camera position data and data from the radar antenna;
- and
- wherein the processor the processor, using programming contained in the computer memory, a cross validation analysis using object detection events from the camera and the radar antenna that suppresses false positive results detected in the object detection events.
