Will This Keep Out Criminals ?

It has been done before, trying to keep criminals out using smoke, So I thought it would be a fun thing to play with and test for myself. This is just a small machine $50 off ebay. The effect after 3-4 min was definitely thick and has some merit to being a deterrent. I think this type of security device would need to be accompanied by a voice announcement that would be very loud and some blue strobe lights.
