Average Cost of a Home Security System

Average Installation Cost of a Home Security System

The average installation costs of a home security system are between $0 and $1,600. Most homeowners pay between $50 and $399 for the installation of their home security system, depending on the equipment installed. DIY home security systems can be installed by the user, which will cost 0$.


DIY Home Security System

The large majority of home security systems nowadays are DIY, which means they are designed to be extremely easy to install. This is done as a way to not only reduce the installation costs to what is essentially zero dollars but also to make these home security systems more appealing and user-friendly.

The average installation cost of a DIY home security system is $0. The costs of DIY systems will include the cost of the equipment and shipping, which will vary depending on your order and location.

If you find yourself in trouble while installing the system, the companies offer over the phone support or professional installation. (Although the customer support usually is entirely free, professional installation is paid.)


Professional Installation

That being said, a lot of people love the DIY aspect of many of the home security systems. However, some systems cannot be installed by the homeowner and require a professional’s touch.

Professional installation of a home security system can vary between $99 and $400 on average. Some more complicated and difficult installations can cost up to and over $800.

Another point worth mentioning here is that what contract you sign is very important.

With some companies, you may not be owning the security equipment and will have to return it once the contract ends. And if you are moving, for example, you may need to bring the system with you to the new address under a new contract, or you may need to talk the new owners into signing a new contract with the company.

This small but important detail can end up increasing your costs depending on what company you choose.


Average Monthly Cost of a Home Security System

On average, the monthly (subscription) costs of a home security system are between $0 and $150, with most homeowners paying about $45 depending on the monitoring service they are using and their system setup. A typical self-monitoring plan costs $0 per month, and professional monitoring plans cost between $15 and $150.

There are two routes you can take here as well. It depends on what system you choose and your budget, but usually, you have two options, (1) a self-monitoring plan, or (2) a subscription-based professional monitoring service.



Some people will not be able to justify the monthly subscription cost, which can be very steep in some instances. However, self-monitoring plans do have their limitations and often offer the most fundamental and basic monitoring features.

Those limitations can be dangerous. What happens if you are in a meeting or somewhere where there is not a good reception, or simply your phone is not around?

A self-monitoring plan will usually cost you $0 per month.



Professionally monitored systems cost, on average, between $15 and $150. The total cost of the monitoring plan will depend on the number of cameras and features.

With that being said, landline security systems are a little cheaper, costing on average $15 to $30, while cellular and Wi-Fi systems cost between $30 and $60.


Average Cost of Additional Equipment In Home Security System Setups

The majority of companies will be offering different home security setups, but they will also be selling additional equipment depending on your needs.

A basic package will usually include a centralized hub or a control panel, a few door or window sensors, and a camera.

Purchasing additional door and window sensors will cost between $15 and $60, motion sensors are between $30 and $50, CO2 detectors are on average $30 to $99, smoke detectors are around $20 and $50, keyfobs cost about $25 to $50, smart locks cost between $150 and $300, cameras will be on average between $100 and $200.

There is other equipment that can be purchased like security signs, panic buttons, temperature and water sensors, glass break sensors, and so much more, which will cost between $20 and $100 on average.

With that being said, the companies mentioned below are the big players that most homeowners use. However, let’s not forget that there are also much smaller local companies that can be better negotiated and often may be able to offer better prices and subscription costs.
