Start with the basics
- Strong doors and locks. Solid-core exterior doors, Grade 1 or 2 deadbolts, and longer strike-plate screws (3 inches) cost little and matter a lot.
- Lighting. Motion-activated lights at entries and dark corners.
- Visibility. Trim shrubs that hide windows and doors.
- Habits. Lock up, don't advertise travel on social media, and use timers for lights.
System components
| Component | What it does |
|---|---|
| Door/window sensors | Trigger when an entry point opens |
| Motion sensors | Detect movement in rooms or hallways |
| Glass-break sensors | Listen for the sound of breaking glass |
| Cameras & video doorbells | Record and stream activity; deter package theft |
| Smoke, CO & water sensors | Protect against the more common non-burglary risks |
| Smart locks | Remote locking, temporary codes for guests |
Monitoring: professional or self
Professional monitoring means a central station contacts you and can dispatch help when an alarm triggers. It usually involves a monthly fee and may lower your homeowners insurance premium.
Self-monitoring sends alerts to your phone and leaves the response to you. It's cheaper but depends on you seeing and acting on every alert.
DIY or professional installation
Wireless DIY kits install in an afternoon and move with you. Professional installation makes sense for hard-wired systems, larger homes, or if you'd rather not configure it yourself.
Questions to ask before signing
- How long is the contract, and what does it cost to cancel early?
- Is equipment purchased or leased? Who owns it if I leave?
- Does the system work during a power or internet outage (battery and cellular backup)?
- Where is video stored, who can access it, and for how long?
- Are there extra fees for false alarms in my city?
Tip: Ask your insurer which kinds of systems qualify for a discount before you buy.
