How to protect against burglary

Imo, a visual deterrent is going to encourage a thief to move on to a different target. I have a walk out basement with large windows at the back of the house. I also have security shutters on each of them that scroll down in a track and interlock producing a solid and formidable obstacle to any would-be thieves. I also have working cameras attached to the eaves and although visible and identifiable, are not obtrusive but small and discreet enough to not be visible from the street. The looks on some of these goofballs' faces at the moment of recognition is really worth the expense. At least for the cameras which are quite inexpensive including the recording equipment. Complete kit with four cameras for around $600.00
