I am trying to find instructional video of this product on how t use it and in what applications to use it in. I want to use it to place on a moving head and the head to move to follow people as they pass by.
Hello @roc4444 and welcome to the forum!
You can find different examples under the Useful Links section of the product page:
You can find some applications here:

However, I don’t think this camera will be suitable for your project because it only detects IR light or heat (like a flame) so humans won’t be enough to trigger the device. I’d suggest checking PIR sensors or a Camera Module.
I hope this information can help you out!
