The sticker price on a home security system tells you almost nothing about what you will actually pay. A system advertised at $199 can easily cost $1,000 or more over three years once you add monitoring fees, camera subscriptions, installation charges, and equipment add-ons. Understanding the total cost of ownership is essential before you commit to any provider.

We broke down every cost component across the six most popular security brands to show you exactly what you will pay upfront, monthly, and over a typical three-year ownership period. No hidden fees, no fine print surprises — just the real numbers.

The Four Cost Components

Every home security system has four potential cost layers. The first is equipment — the base station, sensors, keypads, and cameras that make up the physical system. The second is installation, which is free for DIY systems but can run $99 to $200 for professionally installed setups. The third is monitoring, which is the monthly fee for a central station to watch your system and dispatch emergency services. The fourth is add-ons, including camera cloud storage subscriptions, extra sensors, and extended warranties.

DIY systems like SimpliSafe, Ring, and Abode let you skip installation costs entirely. Professional systems like ADT and Vivint bundle equipment and installation but lock you into long-term contracts that inflate the total cost significantly.

Equipment Costs by Provider

For a standard setup covering two exterior doors, a motion sensor, a keypad, and a base station, here is what each provider charges for equipment alone:

Cove: $149 for the Basic Kit. Includes a touch-screen panel, one door sensor, one motion sensor, and a key remote. Additional door sensors cost $15 each.

SimpliSafe: $200 for the Foundation Kit. Includes a base station, keypad, three entry sensors, and one motion sensor. Additional sensors run $15 to $30 each.

Ring Alarm: $199 for the 5-piece kit. Includes a base station, keypad, one contact sensor, one motion sensor, and a range extender. Additional sensors cost $20 to $30 each.

Abode: $179 for the Smart Security Kit. Includes a gateway, keypad, one mini door sensor, and one motion sensor. Extra sensors cost $25 to $35 each.

ADT: $250 to $1,200 depending on the package. Equipment is customized during a consultation and often bundled with installation. Individual sensor pricing is not publicly listed.

Vivint: $599 to $1,500 for typical packages. Equipment can be financed at 0% APR over 42 to 60 months, which keeps the upfront cost low but extends your commitment.

Monthly Monitoring Costs

Monitoring is where the long-term cost really adds up. Here is what each provider charges per month for their professional monitoring plans:

Wyze: $9.99 per month. Includes 24/7 professional monitoring with Noonlight dispatch. The cheapest professional monitoring available.

Cove: $14.99 per month for Basic (monitoring and dispatch) or $24.99 for Plus (adds remote control, smart home integration, and cloud storage).

SimpliSafe: $19.99 per month for Standard (monitoring, dispatch, and cellular backup) or $29.99 for Fast Protect (adds camera recording and hazard detection).

Ring: $20 per month for Ring Protect Pro. Covers alarm monitoring, unlimited camera cloud storage, cellular backup, and extended warranties on all Ring devices.

Abode: $20 per month for Professional Monitoring. Can be activated and deactivated on a month-to-month basis with no commitment.

ADT: $28.99 to $59.99 per month depending on the plan. Requires a 36-month contract. Early termination fees apply.

Vivint: $29.99 to $49.99 per month. No contract required on monitoring, but equipment financing creates a de facto commitment.

Hidden Costs Most People Miss

Several costs catch people off guard after they have already committed to a system. Installation fees are the most obvious — ADT charges $99 to $199 for professional installation, and Vivint includes it free but rolls the cost into equipment pricing. Early termination fees on contract systems like ADT can run $500 to $1,000 if you cancel before the term ends.

Camera storage is a separate line item for most providers. Even if your alarm monitoring is included, recording and storing camera footage usually requires an additional subscription or a higher-tier plan. SimpliSafe's camera recording requires the $29.99 Fast Protect plan. Ring bundles camera storage into Protect Pro, which is one reason their $20 monitoring is actually good value.

Battery and sensor replacement is a minor but ongoing cost. Most sensors use CR123A or coin cell batteries that last two to five years. A pack of replacements costs $10 to $15. Some providers like Cove ship replacement batteries free of charge.

Permit fees are location-dependent. Some cities require an alarm permit costing $25 to $100 annually. False alarm fines in many jurisdictions start at $50 for the first offense and increase with each subsequent false dispatch. Check your local regulations before activating professional monitoring.

Total 3-Year Cost Comparison

Here is the total three-year cost for a standard setup with professional monitoring at each provider. This includes equipment, installation, monitoring, and camera storage where applicable:

Wyze: $99 equipment + $360 monitoring = $459 total

Cove: $149 equipment + $540 monitoring = $689 total

SimpliSafe: $200 equipment + $720 monitoring = $920 total

Ring: $199 equipment + $720 monitoring = $919 total

Abode: $179 equipment + $720 monitoring = $899 total

ADT: $400 equipment + $150 installation + $1,440 monitoring = $1,990 total

Vivint: $800 equipment + $1,260 monitoring = $2,060 total

Is It Worth the Money?

The average property loss from a burglary in the US is about $2,800 according to FBI statistics. A home security system reduces your burglary risk by roughly 60% according to multiple studies. Many homeowners insurance policies also offer a 5% to 20% discount for monitored security systems, which can save $100 to $300 per year depending on your premium.

At the budget end, a Wyze or Cove system pays for itself through insurance savings alone within two to three years. At the premium end, ADT and Vivint cost more but offer faster response times and more robust equipment. The right choice depends on your budget, your risk tolerance, and whether you value the peace of mind that professional monitoring provides.

If you are on a tight budget, start with a basic system and add components over time. A $149 Cove kit with $15 monitoring provides genuine protection. You can always upgrade later — but you cannot go back in time and prevent a break-in that already happened.
