# Technology ## Overview The sensor uses thermal-sensor fusion in order to classify the foot traffic in your location. This thermal-imaging technology is paired with machine-learning algorithms that optimize the sensor for retail conditions.

Raw thermal data captured from the sensor with detected human in yellow

We train our algorithms in a vast array of different operating conditions so that accuracy is consistent across your deployments. Classification of the number of people, direction of travel, and ignoring other items like shopping carts is all done on the sensor in real time. {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
