- Over 60% of burglars say they would not attempt a home with visible cameras and motion lights — both cost under $50 combined.
- Deadbolt strike plates secured with 3-inch screws instead of the standard 0.75-inch screws increase forced-entry resistance by 700% for under $4.
- Most burglaries take under 10 minutes — deterrence before entry matters far more than monitoring after.
Why Most Home Security Spending Is Poorly Targeted
The security industry profits from recurring subscriptions, but the data on residential burglaries doesn't support professional monitoring as the primary deterrent. Most residential break-ins are opportunistic — an unlocked window, a dark entry, no visible camera, a door that looks forced-entry vulnerable. The average burglar spends less than 60 seconds deciding whether to attempt a home. The decision is made from the street, not after circumventing your alarm.
Professional monitoring calls the police after a break-in begins. A visible camera and a motion light prevent the decision to start one. Only one of those is deterrence.
What Burglars Actually Avoid
Burglary deterrence research consistently identifies three factors that prevent opportunistic break-ins: visible cameras at entry points, motion-activated lighting that eliminates concealment at night, and signs of active occupancy (lights on timers, a car in the driveway). Deadbolt quality and reinforced strike plates matter for forced entry — but most residential break-ins use unlocked doors or windows, not force. Address the easy entry points before investing in higher-security hardware.
Ten Budget Security Upgrades in Impact Order
What Budget Security Spending to Skip
Skip fake alarm company yard signs from businesses you don't use — experienced burglars recognize common sign designs and test the response. Skip window bars unless the window is first-floor and has no other access solution — they create a fire egress problem that outweighs the security benefit in most cases. Skip subscription alarm monitoring unless you are absent from the home for extended periods — the monthly cost rarely returns value compared to the deterrence upgrades above.
The most underused security upgrade costs nothing: tell a trusted neighbor you'll be away and ask them to vary what's visible at your home. An uncollected package and two days of unchanged curtains communicates vacancy more clearly than any other signal.
Recommended methods
Physical Deterrent Upgrades
Best OverallMotion lights, reinforced strike plates, door bars, and shrub trimming address the most common entry vulnerabilities for under $80 total. No electricity, no Wi-Fi, no subscription — just friction.
Smart Camera and Sensor System
Most ThoroughOne video doorbell, one exterior camera, and door/window contact sensors linked to a phone app. Records evidence, deters on sight, and alerts you on entry — no central monitoring fee required.
Occupancy Simulation with Smart Plugs
FastestSmart plugs on lamps randomize lighting schedules to simulate occupancy while away. Pairs with a smart plug on a TV or radio. Costs $15–$30 and deters surveillance-based targeting of vacant homes.
Frequently asked questions
Is home security without a subscription worth it?
Yes for most households. Local-storage cameras, smart sensors with phone alerts, and physical deterrents provide 80%+ of the security benefit of monitored systems at a fraction of the cost. Professional monitoring adds response time — deterrence prevents the need for response.
What is the cheapest effective home security upgrade?
Replacing strike plate screws with 3-inch versions costs under $4 and increases forced-entry resistance by 700%. Followed closely by a $20 motion-activated light at the darkest entry point. Both require under 15 minutes to install.
Do fake security cameras actually work?
Against opportunistic burglars, sometimes — visible cameras of any kind discourage quick decisions. Against targeted break-ins, no. A fake camera costs $15 but a real camera with local storage costs $40–$60 and provides evidence in addition to deterrence.
Should I put security cameras inside or outside my home?
Prioritize outside first — deterrence at the decision point, before entry. One exterior camera at the main entry and one covering the driveway handles 80% of residential security value. Interior cameras add evidence if deterrence fails.
How do I make my home look occupied when I'm away?
Smart plugs on lamps set to random schedules, a radio or TV on a timer, collected mail, and a neighbor who occasionally moves a car or changes something visible. Consistent appearance of occupancy is the strongest deterrent for surveillance-based burglary targeting.
