For standard door sizes, we recommend using TeraRanger Evo 64px to monitor and count the flow of people in an indoor space. This works well for standard sized doors, typically 80cm wide and 2m tall (2'6” by 6'6”).
We wrote a doorway counting algorithm as a proof of concept when developing the product. If you purchase a TeraRanger Evo 64px, you could either write your own algorithm or engage in a project with us to build on our doorway counter technology and accelerate your application development.
We placed a sensor on top of each entry point in order to calculate the number of people entering or leaving. We also detect people passing in front of the door but not passing through it and ensure that they are not included in the count.
For doorway counting, we fixed the sensors update rate to 30 frames per second, which we found to be ideal for identifying even the fastest moving people. As long as they pass through the sensors 15° Field of View, we get a count on them.
Advantages of Terabee's doorway counter devices over other sensor modules
It outputs a matrix of 8x8 high-speed distance readings over a 15 degree Field of View, with a maximum range of up to 5 meters.
As seen on the video, the sensor's matrix output makes it impossible to recognize faces or specific silhouettes, protecting user privacy at all times.
