+ Make the target unappealing (well kept, well lit, reasonably hardened)
+ Alert on attacks (cameras, alarms, dogs)
+ Slow down attackers (hardened doors, window coverings, good locks)
+ Response force
Like fenced home, clearly visual cameras around the place, night sensor lights, dog, security monitoring company?
Perhaps there could be a security monitoring company that used AI human recognition, then users would set their general times. Hence, anyone approaching at night would be pinged by the AI, and a human would verify whether its a security threat or not.
AI being used would be necessary to make 24/7 monitoring across tons of homes possible.
You don't want to look like fort knox. You do want to look just a bit more hardened than your neighbors.
If window bars and serious fences are the norm, do that. If nobody has window bars, don't do that.
AI human recognition misses a lot. AI also can't tell the difference between a girl scout selling cookies and a criminal scouting a place (or a bored uber driver waiting for a slow client).
