Home Security Systems: Types, Costs and How to Choose
A home security system is a set of connected sensors, a control panel, and optional cameras that detect intrusion, fire, and environmental hazards and report them to the homeowner or a monitoring centre. This guide defines the 6 components of a system, the 3 types sold in 2026, cost ranges by type, the 5 steps to choose one, and the 4 cases where professional installation beats DIY.
What Is a Home Security System?
A home security system is a network of 6 components: a control panel or hub, entry sensors on doors and windows, motion sensors inside, environmental sensors for smoke, carbon monoxide, and water, cameras for video, and a communication path (cellular or broadband) to a monitoring centre or your phone.
| Component | Function | Typical 2026 price |
|---|---|---|
| Control panel / hub | Arms the system, sounds the siren, sends alarm signals | $100 to $400 |
| Entry sensors | Detect a door or window opening | $15 to $50 each |
| Motion sensors | Detect movement inside when armed | $30 to $50 each |
| Environmental sensors | Smoke, CO, water leak, freeze | $50 to $100 each |
| Cameras | Doorbell, outdoor, indoor video | $100 to $400 each |
| Communication | Cellular radio, Wi-Fi, battery backup | Built into the hub |
What Are the 3 Types of Home Security Systems?
The 3 types of home security systems are professionally installed and monitored systems (Vivint, ADT, Brinks), DIY-installed and professionally monitored systems (SimpliSafe, Ring, Cove, Frontpoint, abode), and self-monitored camera-only setups (standalone cameras with app alerts and no dispatch).
The 3 types, from most to least service:
- Professionally installed and monitored: a technician installs, a centre dispatches; 36-month agreements are common; $24.99 to $49.99 per month.
- DIY installed, professionally monitored: you mount the sensors, a centre dispatches; no contract; $19.99 to $29.99 per month typical.
- Self-monitored: cameras and sensors alert your phone only; $0 to $10 per month; no dispatch when you cannot respond.
How Much Does a Home Security System Cost?
A home security system costs $200 to $1,500 upfront for equipment and $20 to $60 per month for professional monitoring in 2026, according to HomeGuide, SafeWise, and Security.org; professionally installed systems sit at the top of both ranges, and Vivint, for example, runs $199.99 to $749.99+ upfront and $24.99 to $44.99 per month.
| Type | Equipment | Monitoring / month | Installation |
|---|---|---|---|
| Professionally installed | $200 to $1,500+ | $24.99 to $49.99 | Included or $99 to $199 |
| DIY, pro monitored | $130 to $500 | $8.49 to $29.99 | $0 (self) |
| Self-monitored | $50 to $400 | $0 to $10 | $0 (self) |
The home security cost guide breaks the ranges down by brand, and the Vivint pricing page gives exact figures for one professionally installed system.
How Do You Choose a Home Security System?
To choose a home security system, follow the 5 steps below: count the entry points, decide whether you want dispatch, decide who installs, decide whether cameras are needed, and compare the 36-month total rather than the monthly price.
The 5 steps:
- Count doors and ground-floor windows; each needs a sensor, and each room with valuables needs motion coverage.
- Decide on professional monitoring if nobody can respond to alerts during work or travel.
- Decide on installation: professional for wired cameras, doorbells, and locks; DIY for sensor-only systems.
- Decide on cameras: a doorbell camera for deliveries, an outdoor camera per approach, indoor cameras only where needed.
- Compare 36-month totals: equipment plus 36 monthly payments, including camera storage fees.
When Is Professional Installation Better Than DIY?
Professional installation is better than DIY in 4 cases: wired doorbell or outdoor cameras, smart locks and thermostats that need pairing, large homes with more than 10 sensors, and households that want training and a tested system before the technician leaves.
The DIY vs professional guide weighs cost and reliability, and the Vivint installation page describes a professional install day step by step.
Which Home Security Systems Are Available in 2026?
9 home security systems account for most 2026 sales: Vivint, ADT, Brinks Home, and Xfinity Home among professionally installed systems, and SimpliSafe, Ring Alarm, Cove, Frontpoint, and abode among DIY systems.
