- Alarms are more effective than other security devices.
- Dead bolts, exterior lights, a dog, and a car in the driveway help decrease burglary risk.
- If a home is occupied and/or if the points of entry to a home are visible to persons outside the home, the risk of burglary is substantially reduced.
- Burglars tend to avoid homes that have yard signs indicating alarms.
- A burglar alarm appears to be most merited when household income is above $150,000.
