I guarantee that it’ll trigger an alarm to the shop security and there’ll be officer to see you immediately.

You "guarantee" that? I think it's a possibility, but very far from universal.

Maybe not "every shop," but ones with a security guard monitoring the video who's actually doing his job, trying to "dazzle the camera" would definitely draw extra attention to you, which is probably not what you want.

"Dazzle the camera" is an idea that sounds good when you fail to think about the whole system, and instead hyperfocus on one component.

Bear in mind that lots of large, sophisticated shops have policies of not intervening when someone is blatantly shoplifting.

I think you're overestimating the appetite for confrontation that many shops have.

Not, again, that confrontation is impossible, just that it's not guaranteed.
