How to Prevent Home Burglary: What Actually Works (and What Doesn't)
Most home security advice is outdated. Here is what actually deters burglars based on interviews with convicted burglars and crime data.
What Actually Deters Burglars
Studies of convicted burglars consistently show the same top deterrents. A visible security camera system is the number one deterrent — even visible fake cameras have some effect but real cameras with recording capability are significantly more effective. A barking dog is the second most effective deterrent. An active alarm system with visible signage ranks third. Occupied appearance (lights on, car in driveway, TV sounds) ranks fourth. Burglars overwhelmingly target homes that appear unoccupied with easy entry points and no visible security measures.
Affordable Security Measures That Work
Smart video doorbell like Ring or Nest (100 to 250 dollars) records everyone who approaches your door and provides live alerts. Smart outdoor cameras (50 to 150 dollars each) provide visible deterrence and evidence. Motion-activated outdoor lights (15 to 30 dollars each) eliminate dark areas around entry points. Smart plugs with timers (10 to 15 dollars each) turn interior lights on and off to simulate occupancy when you are away. Window and door alarms (10 to 15 dollars for a pack) sound a loud alarm when opened. Deadbolt locks on all exterior doors (25 to 50 dollars each) — most burglars enter through unlocked doors or flimsy locks.
What Does NOT Work
A security system sign without an actual system provides minimal deterrence — experienced burglars can tell by checking for sensors on windows and doors. Hiding a key under the mat, in a fake rock, or above the door frame — burglars check these locations first. Expensive alarm systems with monthly monitoring fees are not necessarily more effective than a simple local alarm that produces a loud siren. Social media posts announcing vacations tell potential burglars your home is empty.
When You're on Vacation
Stop mail and newspaper delivery or have a neighbor collect them. Use smart plugs to turn lights and a TV or radio on and off at varying times. Ask a neighbor to park in your driveway occasionally. Do not announce your trip on social media until you return. Set your outdoor cameras to alert you of any activity. Consider having a neighbor check the house daily. Lock all doors, windows, and the garage. Set your thermostat to a normal temperature so the house does not look abandoned from thermal imaging.
