How to Choose a Home Security System
Home security systems generally fall into two categories: professionally installed systems with 24/7 monitoring, and DIY systems that you set up yourself with optional self- or professional monitoring. Providers like ADT and Vivint offer full-service professional installation and round-the-clock monitoring, making them a popular choice for homeowners who prefer a hands-off setup and guaranteed response times.
DIY options like Ring and SimpliSafe give you greater control and flexibility. You can install the equipment yourself, often at a lower upfront cost, and choose whether to add a monthly monitoring plan. Smart home integration — connecting your security system to smart locks, cameras, lights, and thermostats — is available from most major providers and can be managed through dedicated apps.
When comparing home security systems, consider the upfront equipment cost, monthly monitoring fees, contract requirements, response time guarantees, the quality of cameras and sensors, and whether the system works with your existing smart home devices.

What is the difference between professional and DIY home security?
Professional home security systems (like ADT and Vivint) are typically installed by a technician, include 24/7 monitoring by a central station, and may require a multi-year contract. DIY systems (like Ring and SimpliSafe) allow you to install equipment yourself and choose optional monitoring plans with more flexible terms.
What is professional monitoring?
Professional monitoring means a central monitoring center watches your system 24/7. If an alarm is triggered, the monitoring team contacts you and can dispatch emergency services if needed. Most providers charge a monthly fee for professional monitoring, separate from the cost of the equipment.
How much does a home security system cost?
Costs vary widely. DIY systems like SimpliSafe start with equipment packages from around $200–$500, with optional monitoring plans from $10–$30/month. Professional systems like ADT or Vivint may include equipment, installation, and monitoring bundled into a monthly plan that typically ranges from $30–$60+ per month, sometimes with a contract.
Do home security systems require a contract?
It depends on the provider. ADT and Vivint typically require multi-year contracts (usually 2–3 years). Ring and SimpliSafe offer month-to-month monitoring plans with no long-term commitment. Xfinity Home and AT&T Connected Life are also month-to-month. No-contract options provide more flexibility to switch providers if your needs change.
Can I use home security without professional monitoring?
Yes. Many systems, including Ring, SimpliSafe, and AT&T Connected Life, allow self-monitoring through a smartphone app. You receive alerts when motion is detected or an alarm is triggered and can respond yourself. This eliminates the monthly monitoring fee but means emergency services will not be dispatched automatically.
Which home security systems work with smart home devices?
Most major home security providers support smart home integration. Vivint and ADT offer deep integrations with smart locks, thermostats, lights, and cameras. Ring integrates with Amazon Alexa. SimpliSafe works with Google Home and Alexa. Xfinity Home integrates with the Xfinity ecosystem. AT&T Connected Life is powered by Google Home.
