The Cost of Home Security Systems: What to Expect in 2021

The Basics of Home Security Systems

Before we dive into the cost, let’s first take a closer look at what a home security system is and how it works.

A home security system typically consists of a control panel, door and window sensors, motion detectors, and sometimes security cameras. These components work together to detect and report any suspicious activity in and around your home.

When an alarm is triggered, either by a door or window being opened or by motion being detected, the system sends a signal to a monitoring center. From there, the appropriate authorities can be notified and dispatched if necessary.

Factors That Impact the Cost of Home Security Systems

The cost of a home security system can vary widely depending on a number of factors. Here are some of the most important:

Type of System

There are several different types of home security systems on the market, including:

  • DIY Systems: These systems can be purchased and installed by the homeowner. They typically involve wireless sensors and mobile app control.
  • Professionally Installed Systems: These systems are installed by a professional, and usually involve hardwired sensors and a control panel.
  • Monitored Systems: These systems are connected to a monitoring center, where trained professionals are available 24/7 to respond to any alerts.
  • Unmonitored Systems: These systems are not connected to a monitoring center and rely on an audible alarm to scare off intruders.


The more advanced features a home security system offers, the higher the cost will be. Some features to consider when looking at home security systems include:

  • Smart Home Integration: Many modern systems can be integrated with other smart home devices, such as Amazon Alexa or Google Assistant.
  • Mobile App Control: With a mobile app, homeowners can arm and disarm their system remotely, receive notifications, and access security cameras.
  • Video Surveillance: Cameras can be installed to monitor the home’s exterior and interior.
  • Professional Monitoring: Trained professionals can monitor the system 24/7 and respond to any alerts.

Size of the Home

The size of your home will also impact the cost of a home security system. Larger homes will require more sensors, cameras, and other components, which will increase the overall cost.

Type of Home

The type of home you have can also impact the cost of a home security system. For example, a single-family home with a large yard and multiple entry points will require more sensors and cameras than a small apartment.

What to Expect in 2021

So, now that we know what factors can impact the cost of a home security system, what can we expect in terms of pricing in 2021? Here are some average costs for different types of systems:

Tips for Saving Money on a Home Security System

If you’re concerned about the cost of a home security system, there are some steps you can take to save money:

  • Look for Promotions: Many home security companies offer promotions and discounts throughout the year. Keep an eye out for these, as they can help you save money.
