Provider-published starting prices for entry-tier configurations, last verified October 2026. Not quotes — pricing varies by address, equipment and promotions.

The equipment

What goes into a typical system

Most packages start with a panel, entry sensors and motion detection, then add cameras and smart-home devices. Exact kits vary by provider.

Installation

What a professional install looks like

  1. 1

    Walk-through and quote

    A specialist reviews the layout of your home and prices the exact system before anything is fitted.

  2. 2

    Professional installation

    A technician mounts cameras and sensors, hides the wiring and connects everything to the panel — usually in a few hours.

  3. 3

    Test and hand-over

    Every device is tested live with the monitoring centre, and you are shown the app before the installer leaves.

Buyer’s guide

What to look for

Monitoring that keeps working

Choose a system with cellular backup, so cutting the internet or the power does not take it offline.

The three-year total

Equipment plus monitoring across the full term is the number that decides cost — not the monthly fee alone.

What cancelling costs

Ask what you would owe in month eighteen. It differs a lot between providers.

Video billed separately

Camera recording is often an extra monthly line. Check before you compare quotes.

FAQ

Questions

How did you rank these systems?

Each provider is scored out of 10 across monitoring and response, equipment and smart-home features, installation and support, three-year cost and contract flexibility, using the weights shown on this page. Our ranking is also influenced by the compensation we receive from the providers listed — see the advertising disclosure.

Is professional installation worth it?

For most homeowners, yes. A pro install puts sensors where they actually catch an intruder, hides the wiring, and ends with a live test with the monitoring centre. All three providers here are professionally installed.

What does home security cost per month?

Professional monitoring from these providers starts around $24.99 to $29.99 a month, rising toward $50 with video recording and smart-home control. Equipment is extra, from about $199 to $599 upfront. See our full pricing breakdown.

Do I have to sign a contract?

Usually 36 months for professionally installed systems, and longer when equipment is financed. If you rent or may move, look at month-to-month options.
