burglars work fast
- **Opportunity matters most** — Most burglars are opportunistic, not skilled professionals. Easy targets get hit.
- **Visibility deters** — Burglars avoid homes where they might be seen. Good lighting and sightlines matter.
- **Speed is priority** — Anything slowing entry (better locks, noise) makes your home less attractive.
- **Signs of occupancy** — Homes that look occupied are skipped. Empty houses scream

Layers of Security
Think in layers: perimeter (yard, fence), entry points (doors, windows), interior (safe, sensors), and response (alarm, neighbors). No single measure is perfect—layers compound protection.
2Securing Doors: Your First Line of Defense
Doors are the most common entry point for burglars. Strengthening them provides the biggest security return on investment.
| Lock Type | Security Level | Cost | Notes |
|---|---|---|---|
| Standard deadbolt | Medium | $20-50 | Better than knob locks; choose Grade 1 or 2 |
| Smart lock | Medium-High | $100-300 | Convenience + auto-lock; pick-resistant models |
| High-security deadbolt | High | $100-200 | Pick/drill resistant; Medeco, Mul-T-Lock |
| Double-cylinder deadbolt | High | $50-100 | Keyed both sides; prevents glass-break entry |
| Smart lock + deadbolt | High | $200-400 | Best of both: convenience + physical strength |
Door Hardening Checklist
1
Upgrade to Grade 1 or 2 deadbolt
ANSI Grade 1 is commercial-strength; Grade 2 is strong residential. Avoid Grade 3.
2
Install 3" screws in strike plate
Replace short screws with 3" screws that reach the wall studs. This prevents kick-ins.
3
Add door reinforcement kit
$50-100 kits reinforce the door jamb, hinges, and strike plate—dramatically increases kick resistance.
4
Install a peephole or video doorbell
See who's there before opening. Video doorbells record and alert your phone.
5
Consider a security bar or door jammer
Floor braces add resistance when you're home. Simple, cheap, effective.
6
Don't forget the garage
Attached garage doors need secure locks. Interior garage-to-house door should be solid core with deadbolt.
A hollow-core door can be kicked through regardless of locks. Exterior doors should be solid wood, steel, or fiberglass. Check door thickness—should be 1¾" minimum.
Sliding Glass Doors
Sliding doors are vulnerable. Add a security bar in the track, install anti-lift pins, and consider security film to prevent shattering. A secondary locking mechanism (Charlie bar) adds another layer.
3Window Security Measures
Windows are the second most common entry point. Ground-floor and hidden windows need the most attention.
| Measure | Cost | Effectiveness | Notes |
|---|---|---|---|
| Window locks | $5-15/each | Medium | Replace flimsy factory locks with keyed locks |
| Security film | $6-12/sq ft installed | Medium-High | Holds glass together when broken; delays entry |
| Window sensors | $10-30/each | Medium | Alert when opened; part of alarm system |
| Glass break sensors | $20-50/each | Medium | Detect breaking glass via sound/vibration |
| Security bars/grilles | $100-300/window | Very High | Physical barrier; cosmetic concerns; fire code issues |
| Window pins | $2-5 | Medium | Prevent sliding windows from being pried open |
| Thorny bushes | $20-50/plant | Medium | Natural barrier; roses, holly, hawthorn |
- **First-floor windows** — Top priority, especially those hidden from street view.
- **Basement windows** — Often forgotten but easily accessed. Consider window well covers.
- **Windows near doors** — Can reach in to unlock door. Security film is essential here.
- **Air conditioner units** — Can be pushed in. Secure with brackets or sensors.
- **Skylights** — Rarely used for entry but can be; sensor if accessible.
Security window film is underrated. For about $200-400 professionally installed, it makes windows nearly impossible to smash through quickly—burglars give up.
Balance security with fire safety. You must be able to exit windows in an emergency. Avoid interior bars without quick-release mechanisms.
4Alarm Systems: DIY vs. Professional
Alarm systems provide monitoring and deterrence. Modern DIY options rival professional systems at lower cost.
| Feature | DIY Systems Self-install, self or optional monitoring | Professional Systems Installed and monitored by company |
|---|---|---|
| Installation | Self-install (1-3 hours) | Professional install |
| Upfront cost | $150-500 | $0-500 (often subsidized) |
| Monthly fee | $0-25 (optional monitoring) | $25-60 |
| Contract required | None usually | 2-3 year typical |
| Ideal for | Renters, budget-conscious, tech-savvy | Homeowners, non-technical, comprehensive needs |
| Top brands | Ring, SimpliSafe, Wyze, Abode | ADT, Vivint, Frontpoint |
- **Base station/hub** — Central brain that connects all sensors and communicates with monitoring.
- **Door/window sensors** — Detect opening; most important component after base.
- **Motion sensors** — Detect movement inside; use pet-immune models if you have animals.
- **Glass break sensors** — Detect shattering sound; covers multiple windows.
- **Keypad** — Arm/disarm the system; consider adding entry delay.
- **Siren** — Loud alarm (100+ dB) scares intruders and alerts neighbors.
- **Monitoring** — 24/7 call center that contacts you and police when triggered.
Monitoring Options
Self-monitoring (app alerts) is free but relies on you responding. Professional monitoring ($15-30/month) contacts police even if you\
Place visible alarm yard signs and window stickers even if you don\
5Security Cameras and Surveillance
Cameras provide evidence, remote monitoring, and deterrence. Modern options are affordable and easy to install.
| Camera Type | Best For | Cost | Considerations |
|---|---|---|---|
| Doorbell camera | Front door monitoring, package theft | $80-250 | Video calls with visitors; hardwired or battery |
| Outdoor camera | Yard, driveway, perimeter | $50-300 | Weather-resistant; wired has best reliability |
| Indoor camera | Interior monitoring when away | $30-150 | Privacy concerns; disable when home |
| Floodlight camera | Dark areas, driveways | $150-300 | Bright light + camera combo |
| PTZ camera | Large areas, zoom needed | $200-500 | Pan-tilt-zoom; overkill for most homes |
- **Resolution** — 1080p minimum; 2K or 4K for detail (license plates, faces).
- **Night vision** — Essential; infrared (B&W) or color night vision.
- **Two-way audio** — Talk to visitors or scare off intruders.
- **Motion detection** — Smart detection (people vs. cars vs. animals) reduces false alerts.
- **Storage** — Cloud (monthly fee) vs. local (SD card, NVR). Both have pros/cons.
- **Power** — Hardwired (reliable) vs. battery (flexible but needs recharging).
- **Integration** — Works with your smart home ecosystem (Alexa, Google, Apple).
Camera Placement Priorities
1
Front door
Doorbell camera captures faces of everyone who approaches. Most important single camera.
2
Back door
Often targeted because it's less visible. Outdoor camera with night vision.
3
Driveway/garage
Captures vehicles and approach from street. Floodlight camera ideal.
4
First-floor windows
Cover vulnerable hidden windows, especially sides of house.
5
Interior
Optional but useful for catching intruders who evade exterior cameras.
Check local laws before installing cameras. Most areas allow outdoor cameras on your property but not pointed at neighbors\
Position cameras at face height (5-6 feet) pointed slightly downward for the best identification footage. Too high = top of head shots.
6Lighting as Security
Lighting is the simplest, most cost-effective security measure. Burglars hate being seen.
| Lighting Type | Best For | Cost | Notes |
|---|---|---|---|
| Motion-sensor lights | Sides, back, dark corners | $20-100 | Startles intruders; saves energy |
| Dusk-to-dawn lights | Front porch, walkways | $20-50 | Automatic on at dark |
| Smart bulbs | Interior lights, simulation | $15-40/bulb | Control remotely; simulate occupancy |
| Floodlights | Driveways, large areas | $30-100 | Bright coverage; motion or always-on |
| Solar path lights | Walkways, yard edges | $20-50/set | No wiring; limited brightness |
| Timer-controlled | Interior when away | $10-20/timer | Automatic on/off schedule |
- **Eliminate dark corners** — Walk your property at night. Where could someone hide?
- **Layer lighting** — Combine motion-sensor and always-on for best coverage.
- **Light entry points** — Every door and vulnerable window should be illuminated.
- **Interior visibility** — Leave a light on in a visible room when away. Smart bulbs automate this.
- **Consider neighbors** — Don\
- ,
Vacancy Simulation
When traveling, use smart plugs or bulbs to turn lights on/off at varied times. Static patterns are obvious. Randomized schedules look like real activity.
LED motion lights are cheap to run—leaving them active costs pennies per month. Don\
7Smart Home Security Integration
Smart home technology lets you monitor and control security from anywhere. But it requires thoughtful setup to avoid vulnerabilities.
- **Smart locks** — Lock/unlock remotely, give temporary codes, see access history.
- **Video doorbells** — See and speak to visitors from anywhere via app.
- **Smart cameras** — Live view, motion alerts, cloud recording.
- **Smart lights** — Automate schedules, simulate occupancy, control remotely.
- **Smart plugs** — Turn any lamp into a smart light; control small appliances.
- **Smart garage door** — Know if it\
- ,
Smart devices can be hacked if poorly secured. Use strong unique passwords, enable two-factor authentication, keep firmware updated, and buy from reputable brands. Cheap no-name devices often have security flaws.
Securing Your Smart Home Network
1
Secure your WiFi
WPA3 or WPA2 encryption, strong password (not "password123"), hide SSID if desired.
2
Create a separate IoT network
Many routers support guest networks. Put smart devices on a separate network from computers.
3
Update firmware regularly
Manufacturers patch security holes. Enable auto-updates or check monthly.
4
Use unique passwords for each device
If one device is compromised, others remain secure. Use a password manager.
5
Enable two-factor authentication
For all apps that control your devices, especially locks and cameras.
6
Disable features you don't use
Remote access, voice control, etc. create attack surface. Disable if not needed.
Consider what happens if the internet goes down. Smart locks should have physical key backup. Local processing (not cloud-dependent) devices work offline.
8Behavioral Security: Your Habits Matter
No technology compensates for poor habits. Security is a practice, not just equipment.
- **Lock doors always** — Even when home, even when leaving for 5 minutes. Make it automatic.
- **Close garage door** — Open garage is an invitation. Close it immediately after entering/exiting.
- **Don\
- t post real-time travel photos. Tell trusted neighbors, not social media.
- **Secure spare keys** — Not under doormat, not under flower pot. Use a lockbox or trusted neighbor.
- **Be careful with service workers** — Verify identities. Don\
- ,
- t advertise new purchases.
When You're Away
Stop mail and packages or have neighbor collect them. Use timers on lights and TVs. Have someone mow lawn/shovel snow. Park a car in driveway. All create the appearance of occupancy.

9Security for Renters and Apartments
Renters face unique challenges—you can't always modify the property. But many effective security measures require no permanent changes.
| Measure | Modification Level | Effectiveness |
|---|---|---|
| Door security bar | None | High |
| Portable door lock | None | Medium-High |
| Window security film | Removable | Medium-High |
| Wireless alarm system | None (adhesive) | High |
| Smart lock (retrofit) | Swap original lock back | High |
| Portable motion sensor | None | Medium |
| Video doorbell (battery) | None | High |
| Window pins | Small holes | Medium |
- **Check existing locks** — Request lock rekey when moving in. Previous tenants may have keys.
- **Add chain or swing bar** — Most landlords allow interior chains. Adds layer when home.
- **Use door reinforcement** — Portable door jammers/security bars work in any door.
- **Wireless cameras** — Battery-powered, no drilling. Take them when you move.
- **Smart plugs for lights** — No installation, full control over lighting schedules.
- **Meet building staff** — Good relationships with doormen, supers, neighbors = eyes on your unit.
- **Document everything** — Photo inventory for insurance. Store copies in cloud.
- **Renter\
Negotiate With Landlord
Many landlords will install better locks or security measures if you ask—especially if you offer to pay or leave improvements behind. It increases property value.
Check your lease before installing anything. Some prohibit drilling, adhesives, or smart locks. Get written permission for permanent modifications.

Browse Lifestyle ToolsFrequently Asked Questions
Do security cameras actually deter burglars?
Yes, studies show visible cameras significantly deter burglars. However, placement matters—cameras should be obvious and cover entry points. Some burglars will wear masks or hoodies if they see cameras, so cameras are best paired with other measures like alarms and good lighting.
Is a security system worth it if I don’t pay for monitoring?
Self-monitored systems still provide deterrence (signs/stickers), local sirens that scare intruders and alert neighbors, and phone alerts so you can call police yourself. Professional monitoring adds 24/7 response even when you’re unavailable, which is valuable for peace of mind.
What’s the most important security upgrade for my home?
Reinforcing your front door. It’s the most common entry point and often the weakest. A door reinforcement kit ($50-100), 3-inch strike plate screws, and a Grade 1 or 2 deadbolt make kick-ins nearly impossible. This single upgrade stops most break-in attempts.
Are smart locks safe?
Reputable smart locks from major brands (Schlage, Yale, August, Kwikset) are secure when properly configured. Use strong unique PINs, enable two-factor authentication, keep firmware updated. The convenience benefits (remote locking, temporary codes, no hidden keys) often outweigh small additional cyber risks.
How can I secure my home as a renter?
Focus on non-permanent solutions: portable door security bars, wireless DIY alarm systems, battery-powered cameras, smart plugs for lights, and window security film (often removable). Ask landlords about rekeying locks. Many renter-friendly options are highly effective and move with you.
