Physical stuff (window bars and a security door) is much, much more effective for that logic.

Burglars know they’ll probably be on CCTV somewhere anyway but nobody in their right mind is trying to smash through a security door or saw through some window bars when there’s a house up the street that doesn’t have them.

Obviously there are downsides (cost, aesthetics) but those solutions actually work, I’m skeptical that a fancy subscription doorbell makes much difference
