Helo @Edmund and welcome to the forum!
I checked the camera you linked on Amazon and although it looks like a great solution for intruder tracking, doesn’t seem to be the best for custom object tracking as it only offers three tracking modes (line cross, intrusion and preset) all of which track any moving object. It doesn’t seem like it allows only tracking a specific object (like the football white ball). So I think it is better to opt for another option so as not to “waste” the capabilities of that camera for the task you mention.
Some options I can think of are to use a smart camera that allows you to track a specific object, you can find some options here.
Or if you feel comfortable programming the options that scharette mentioned are great, which in a few words are to use any camera that you consider fits your task (resolution/FPS/FOV) and use a SCB (like a Raspberry Pi or even better a Jetson module) to analyze the frames. There are many algorithms to detect objects either based on color or even more robust Deep Learning solutions that you can use to track any type of object. If you are interested in that, as scharette suggested, check OpenCV documentation and tutorials

I’m also working on something very similar so you may want to check this thread as well:
I hope that helps
