The project’s open-source nature acts as an ethical safeguard, and I am explicitly not pursuing any identity recognition features, just movement detection.

But you are absolutely right that, in theory, misuse of this technology could reveal certain behavioral patterns that might lead to identification.

However, it can also be extremely useful for safety purposes, for example, detecting people during a house fire or an earthquake.

This particular project isn't what terrifies me. It's the technology itself which I'm certain you won't be the last to develop and quite likely not even the first. There are plenty of state actors that likely already have their hands on a technology like this or are working on it
