TryAlarms is a free comparison service supported by advertising. We receive
compensation from some of the companies listed on this page, and that compensation may affect how and where they appear,
including their ranking and rating. We do not list every home security provider or every offer available. Scores
reflect our editorial judgement using the method shown below.
We put the leading professionally installed systems side by side — monitoring, equipment,
installation, three-year cost and contract terms — so you can pick in minutes, not weekends.
*Requires system purchase (minimum $349 DIY or $599 professional install) and a professional monitoring plan from $24.99/mo with a 1-month minimum (DIY) or $34.99/mo for 36 months (professional install). Early cancellation fees apply. Not available for online orders. See ADT for full terms.
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.
Control panel
The hub: arms the system and talks to the monitoring centre.
Video doorbell
See and speak to whoever is at the door, from anywhere.
Outdoor camera
Covers the driveway, yard or back door, day and night.
Door & window sensors
Trip an alarm the moment an entry opens.
Motion detector
Watches a room or hallway without a camera.
Indoor camera
Check on kids, pets or a package drop-off.
Smart lock
Lock up or let someone in from the app.
Smoke & CO detector
Monitored, so help is sent even when you are out.
Installation
What a professional install looks like
1
Walk-through and quote
A specialist reviews the layout of your home and prices the exact system before anything is fitted.
2
Professional installation
A technician mounts cameras and sensors, hides the wiring and connects everything to the panel — usually in a few hours.
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.
Our #1 pick
Vivint — Get 5 months of free monitoring with code 5FREE
Professional installation, 24/7 monitoring and full smart-home control from one app.
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.
