I believe it would require a specific ML model to be trained, due to the slight variances in the hardware and each environment. This means you would also need the hardware to run the model 24/7.
It could definitely be done, and I suspect the fascist surveillance state already has projects to weaponize it; they're probably also building the capability into the 6G or 7G spec, so they can monitor everything, everyone, everywhere, 24/7 from cell towers alone.
