Prefer installing modern security systems that bite back.
E.G
Fog Bandit, the fastest security fog generation system. If it can't be seen, it can't be stolen or trashed.

Inferno, produces 125Db of oscillating sound to cause nausea and migraine.

Self Monitored (or Monitoring Station) wireless alarms with combined sensor/camera that records cause of movement and send image immediately to smart phone or Monitoring Station.  External sensors detect intruders (but not animals) before they have entered the property. Remote arming/disarming.

Rapid deployment, no mains required, battery powered (4 year life) external/internal systems that send 10sec video of the cause.  Ideal for security where power is not available.

In other words - anyone can put a bell on the wall, but what happens next is probably more important.

And above all, keep it simple
