Not “defeats”, exactly. Many consumer-level security cameras are designed to alert the owner to activity when they aren’t home. If my camera tells me that there’s activity in my house when I’m out at dinner, and the included screenshot shows me somebody who isn’t supposed to be in my home, I still get to call the police to my house. No clothing choice is going to circumvent that.
Wire cutters do indeed work, but only if the wires are exposed. And given that most home burglaries are crimes of opportunity, any home that is going to require more tools to burgle than the house next door is likely going to get a pass.
