I am looking for a thermal camera that detects people's heads

Need your help,
I am looking for a thermal camera that detects people’s heads that will connect to a controller, when it detects 2 people it turns off dry contact when it sees one person it turns on dry contact

When it detects 2 people, it does not open the door because it detected 2 people. I want it to wait and only then open the door when it detects one person.

Hi Tzvika

Welcome to the forum!

This is definitely an interesting project, while it would definitely be possible I would instead suggest using a regular camera and image recognition software such as OpenCV which we have a guide on to achieve what you’re looking to do.

My reasoning for this is that thermal camera readings can be skewed by clothing or reflective surfaces, they are also generally speaking rather expensive in comparison to a standard camera.

Hi Dan and Tzvika

If what you are after is anything like the thermal cameras pest inspectors use to detect termites and other nasties in buildings I think you could read “VERY expensive”

You can use a Raspberry Pi with a thermal camera module combined with OpenCV or TensorFlow to detect and count people.
