Store Security Cameras

I'd like to know everyone's thoughts on the ever growing number of security cameras in retail stores. It's more common to see them in smaller mom and pop shops where the owner is trying to keep a eye on employees (priorities) and if you do happen to shoplift from them, they'll most likely be able to see you from the camera pointed at the cash register. If you're feeling brave enough to steal from a bigger retail store, you'll see the typical cameras in the corners of the ceiling. Sometimes I'd see cameras in the stockrooms. If I'm lucky I don't see any cameras at all like the Dollar Store. <br><br>I did a quick search on Reddit and it was suggested that they're used to monitor employee activity, loss prevention, deter crime, and if a customer were to slip and fall and file a claim against the store, the cameras would serve as evidence. But do you think they use the camera footage to look for shoplifters? If so, do they search for shoplifters on an active, real time basis, or do they only review footage after an incident has been reported? Are they reviewing footage after every single incident of shoplifting that's reported or just the major ones? I read on this r/nosleep post called "The camera in my store was pointed wrong. I'm glad. (As told by my friend)" that when a <br>store employee is stocking shelves and a customer reports something odd like "I saw that item on the shelf" when it's been in the stockroom the whole time, they'll review the camera footage to see if they were right. If they're not, they were just making it up. I'm assuming they only do this for minor incidents as I don't think they'd waste their time for the bigger ones like actual shoplifting.
