Home security has never been more affordable — or more confusing. With dozens of cameras, locks, sensors and subscription plans on the market, most homeowners either buy too little (a single doorbell cam) or too much (a $4,000 system with features they'll never use). Here's how our installers actually think about securing a home.
Step 1: Start With the Basics That Matter Most
Before any technology, security is physical: solid doors with deadbolts, secure window locks, good exterior lighting and trimmed landscaping (no hiding spots near entry points). Lights are the cheapest deterrent that exists — a well-lit entryway eliminates most opportunistic attempts.
Step 2: The Core Layers of a Smart System
Video Doorbell ($100–$300)
The single highest-value device. Modern doorbells offer 2K/4K video, two-way audio, package detection and 24/7 recording with cloud or local storage. Place it to see the full approach to your door — not just the door itself.
Smart Locks ($150–$350)
Keypad or fingerprint entry, temporary codes for houseguests and contractors, and deadbolt status alerts. The "connected to your phone" convenience alone is worth it — no more hiding keys under the mat.
Security Cameras ($80–$250 each)
Cover, at minimum: front door, back door, garage, driveway and any side gates. Look for 1080p or higher resolution, night vision, motion zones (so passing cars don't trigger alerts), and local storage options if you're privacy-conscious.
Entry Sensors ($15–$40 each)
Contact sensors on ground-floor doors and windows detect openings when the system is armed. They're cheap, invisible and the backbone of any alarm.
Step 3: Monitoring — Do You Need It?
There are three levels:
- Self-monitored (free): You get instant phone alerts and check cameras yourself. Great for most homeowners.
- Professional monitoring ($20–$50/month): A central station dispatches police/fire when alarms trigger — essential if you travel often or want hands-off protection.
- Hybrid: Professional monitoring for door/window alarms, self-monitored cameras.
Our honest advice: monitoring subscriptions are where companies make their margins. Match the plan to your lifestyle — don't let a salesperson upgrade you.
Step 4: Placement Mistakes We See All the Time
- Cameras mounted too high — 8–10 feet is the sweet spot; higher than that and you can't identify faces.
- No coverage of the garage — the #1 break-in target in suburban Texas.
- Doorbell cameras angled at the door only — you miss the porch pirates approaching from the side.
- Sensors on interior doors instead of exterior ones.
- Weak Wi-Fi — cameras at the far end of the house drop offline constantly. Mesh Wi-Fi or wired PoE cameras fix this.
Step 5: Privacy & Security of the System Itself
Ironically, smart home devices are a favorite target for hackers. Do three things: use unique passwords on every device, enable two-factor authentication on your accounts, and keep firmware updated. If a brand has a poor security track record, skip it — no matter how cheap.
What Does a Professional Installation Add?
DIY is fine for a doorbell cam. But whole-home systems benefit from professionals: proper placement planning, wiring and power solutions, Wi-Fi optimization, integration with existing smart-home gear, and — most importantly — a system that actually works together, not five apps fighting for your attention.
