Proper home defense is one of those things that many people tend to think is a single solution..I took a class a few years ago talking about home defense. They taught about security lights, locks, security systems, even landscaping to prevent or deter break-ins. Then they taught tactical home defense which I like the best..things like remember you know your house they don't, small targets are harder to hit, muzzle flashes in a dark room will blind you and them so be sure you can hit what you want to in the first 3 rounds.
