STEREO INFRARED DETECTOR
First Claim
1. An apparatus for detecting a source of infrared emission, the apparatus comprising:
- a first infrared sensor configured to provide at least one first image;
a second infrared sensor configured to provide at least one second image; and
a processor operatively coupled to the first and second infrared sensors and configured (i) to process the first and second images in conjunction with each other to detect a presence of a source as a function of the first and second images and (ii) to output a signal based on the presence of the source.

Abstract
Existing passive infrared (PIR) sensors rely on motion of an object to detect presence and do not provide information about the number of objects or other characteristics of objects in a field of view such as distance or size. Disclosed herein are apparatuses and corresponding methods for detecting a source of infrared emission. Example embodiments include two infrared sensors for imaging and a processor configured to use the images to detect a presence of an infrared source and output a signal based on the presence. Example apparatuses and corresponding methods provide for measurement of an infrared source'"'"'s speed, size, height, width, temperature, or range using analytics. Some advantages of these systems and methods include low cost, stereo view, and detection of people, children, or objects with infrared/thermal sensors of low pixel count.
