Shoplifting/Theft Question

We’ve been having quite a few shoplifters at out store recently. Most fellow employees on this subreddit will know we aren’t supposed to confront the thieves directly, so my question is, what happens to the shoplifters? My manager says our store doesn’t keep track of them which seems odd, and we don’t even call the police. Do other stores also not have any sort of loss prevention??? For a problem that seems so big (at our store at least) I would think there would be a way to use facial ID or something to track them so we know when they come in.
