The Real Threat Model
Before buying anything, understand how most residential break-ins actually happen. Burglars are opportunistic. They pick unlocked doors, unlit entry points, and houses that look empty. They do not pick locks. They do not bypass alarm systems. They test a door handle, and if it opens, they walk in.
That means the highest-leverage moves are boring: deadbolts, lighting, and the habit of actually locking things. Technology amplifies a solid physical baseline. It cannot replace one.
What to Install First
1. A Grade 1 Deadbolt - Smart or Dumb
Your front door and any other exterior entry needs an ANSI Grade 1 deadbolt. This is the physical foundation everything else builds on. A $30 deadbolt from a hardware store outperforms a $200 smart lock installed on a hollow-core door.
If you want a smart lock, 2026 is a good year to buy. Matter-certified models now work across Apple HomeKit, Google Home, and Alexa without proprietary hubs. Kwikset Halo Select (~$120) and Schlage Encode Plus (~$230) are the reliable mid-range options. Both carry ANSI Grade 1 ratings, support Matter, and include a physical key backup. Do not buy a smart lock without a physical key fallback.
What you can skip: biometric-only entry and facial recognition locks. They add friction and failure modes without meaningfully improving security over a keypad plus deadbolt.
2. Motion-Activated Lighting
This is the second-highest-ROI item in residential security. Motion lighting deters entry, improves camera footage quality, and costs $30 to $80 per fixture. Cover the front door, driveway approach, backyard, and any side entry with poor sightlines.
It is not a nice-to-have. It is the layer most often skipped and most often regretted.
3. One Camera System - Not Four Apps
You need cameras on your front door and at least one secondary angle covering the driveway or walkway approach. A doorbell camera alone is not enough. Someone who knows it is there will simply avoid looking at it. A second wide-angle camera on the approach captures what the doorbell misses.
In 2026, the meaningful distinction between cameras is not resolution. It is AI detection quality and storage independence.
- Distinguish people, vehicles, animals, and packages, not just generic motion
- Record locally to microSD or a hub, not cloud-only
- Support color night vision, not just infrared
Cloud-only systems fail when your internet goes down or when a Wi-Fi jammer, a documented tactic in residential burglaries, cuts connectivity. Local recording means evidence exists regardless.
On subscriptions, most reputable cameras now offer onboard AI and local storage with no monthly fee. Arlo, eufy, Reolink, and aosu all have subscription-free options with legitimate AI detection. You do not need a cloud plan for basic functionality. If you want cloud backup, one plan covering your whole system is enough. Do not pay per-camera fees across multiple brands.
What you can skip: indoor cameras in every room, 4K on everything, and cameras from more than one brand. That creates app fragmentation and you end up checking nothing.
4. Door and Window Sensors
Cheap, reliable, and often the fastest alert you will get. Put sensors on every ground-floor door and window, plus any second-floor window reachable by ladder. Most alarm hubs include these in starter kits.
This is where a simple hub system like SimpliSafe, abode, or Cove earns its place. Not for the monitoring contract, but as the central brain that ties sensors, cameras, and alerts into one app. Cove starts around $300 for an eight-piece system. That covers a realistic ground-floor perimeter.
What you can skip: glass break sensors. They add marginal value over door sensors and motion detection already covering the same windows.
The Monitoring Question
Professional monitoring is optional. Self-monitoring via app is genuinely adequate for most households. The argument for professional monitoring is response speed when you are unavailable. The argument against is paying $15 to $50 per month indefinitely for a feature most people rarely need.
If you do want professional monitoring, pick one provider and use their cameras. Do not buy a separate camera subscription on top of a monitoring subscription. You will end up paying twice for cloud storage and alert processing that overlap significantly.
If you self-monitor, make sure local recording is configured and tested. An alert that goes to your phone while you are asleep on a plane is useless without footage that exists when you land.
The Network Layer
Your cameras and smart lock are on your home network. If that network is soft, your security system is soft.
Three things actually matter here:
- Put IoT devices on a separate network. Most modern routers support a guest network or VLAN. Your camera should not be on the same network as your laptop. If a camera is compromised, the blast radius stays contained.
- Change default passwords on every device. Still the most violated basic rule in residential security.
- Enable automatic firmware updates. Unpatched cameras and hubs are the most common vector for device compromise.
Everything else like MAC address filtering, intrusion detection systems, and Suricata on a Raspberry Pi is optional hardening for people who want it, not a baseline requirement.
What You're Probably Paying Twice For
- Cloud storage plus professional monitoring. Both include video storage. Pick one or understand explicitly what you are getting from each.
- Multiple camera brand subscriptions. Arlo Secure, Ring Protect, and Nest Aware can add up to a meaningful monthly bill with overlapping features.
- A security system and a smart home hub. Many alarm hubs now double as Matter controllers. You may not need a separate HomePod or Echo if you are starting fresh.
The Honest Short Stack
| What | Why | Cost |
|---|---|---|
| Grade 1 deadbolt (smart, Matter) | Physical foundation, remote access, audit log | $120-230 |
| Motion lighting (2-3 fixtures) | Deterrence plus camera quality | $80-200 |
| Doorbell camera plus 1 wide-angle | Front coverage with redundant angle | $150-300 |
| Alarm hub plus door/window sensors | Perimeter awareness, single app | $250-400 |
| Separate IoT network | Contain device risk | $0 (router setting) |
| Total | ~$600-1,100 |
No monitoring contract required. No overlapping subscriptions. One app for alerts.
A partially implemented version of this, just the deadbolt, lighting, and sensors, is still meaningfully better than most setups. Start with what you will actually use, configure it properly, and test it. That is a real security setup.
