If you want peace of mind that your home is protected when you’re out of town or asleep at night, you should consider investing in a home security system.
These systems can help you rest easy with features like 24/7 professional monitoring, emergency service alerts, and more. Some even add convenience to your everyday life with smart home automation.
There are many home security systems on the market, but they can differ in terms of contract requirements, installation methods, cost, available equipment, and more. The This Old House Reviews Team created this in-depth guide on how to choose a home security system and included our top recommendations.
Factors to Consider When Choosing a Home Security System
Unfortunately, choosing the best alarm system for your home isn’t as simple as going with the first option or choosing the cheapest package. From method of installation to equipment, there are many factors to consider when choosing a home security system.
Professional vs DIY Installation
Some providers will offer you the choice between professional or DIY installation, while others won’t give you an option. There are pros and cons to each type of installation.
Professional installation is typically performed by experienced security experts who can walk you through the process and install equipment in locations that maximize protection. However, professional installation means you have to work around someone else’s schedule, let them into your home, and typically pay for the installation cost. Fees typically range from $99 to $199, but the cost of professional installation can go even higher.
DIY installation means you won’t benefit from professional expertise, but luckily many DIY systems come pre-programmed so that all you have to do is set them up. Many DIY security systems also offer peel-and-stick adhesive equipment, meaning you won’t have to worry about drilling holes in your wall.
When it comes to the cost of a home security system, there are several categories to consider: equipment cost, installation cost, activation fees, and monitoring costs—as well as any hidden fees.
The cost of equipment will vary widely from provider to provider and from package to package. Keep in mind that the cheapest package doesn’t always have the best value. You should balance your budget with your priorities to find the best fit. Some providers charge an activation fee in addition to the upfront equipment cost, but not all do.
If you choose a professionally installed system, prepare to have at least $100 ready to cover the fee. Some providers offer professional monitoring services while others only operate with DIY monitoring. In general, providers offer several levels of protection with monthly monitoring plans—beginning with a starter kit and ending with a more advanced alternative.
Always be sure to read the fine print, especially when it comes to costs you might not have considered like cancellation reinstallation fees.
Some home security systems require you to sign long-term contracts that can be up to a three-year commitment. Others offer short-term contracts or don’t require one at all. This can be a plus if you plan on moving or if you don’t want a long-term commitment.
One key consideration is whether you want to do DIY monitoring or professional monitoring. Some providers offer both, letting you pick the one that suits your specific needs.
Professional monitoring provides round-the-clock protection from experts who are alerted as soon as an alarm is triggered. The experts can investigate the issue and contact emergency services if needed. Professional monitoring comes with a monthly fee.
Monitoring your system yourself means no professional monitoring fees, but it also requires you to be responsible for notifying the authorities when needed. With DIY monitoring, you will still receive alerts and notifications if your alarm is triggered.
Smart Home Integration
Certain home security systems can be integrated with third-party smart home devices like the Nest thermostat, Kwikset smart lock, Philips Hue smart light, Amazon Alexa, Google Assistant, and more.
Home automation can add convenience as well as save you money. Home automation lets you customize controls to fit your routine. For example, you can set your thermostat to adjust automatically each morning when you leave for work.
Type of Equipment
Some providers allow you to lease your equipment while some only let you purchase it. Other providers will give you the choice between the two. A key factor to consider is whether or not your equipment is wired. A wireless system is a good choice if you plan to move or have pets or small children who might accidentally interfere with the equipment.
Type of Connection
If you choose professional monitoring, you’ll need a connection to the center. There are three connection options: landline, broadband, and cellular.
With a landline, the provider uses the home’s landline connection to notify the monitoring center of an alert. Connecting to a landline is the least expensive option but also the easiest to tamper with. If someone cuts the line, you no longer have a connection to the monitoring center.
If you have high-speed internet, you can use a broadband connection to communicate with the monitoring center. Unfortunately, your connection is lost if the power goes out. Some providers offer backup batteries to make sure that your system stays functional even if the Wi-Fi cuts out.
Cellular monitoring operates with a built-in chip that sends alerts to the monitoring center using the same signal your phone uses to make calls and send texts. It’s a reliable method because it can’t be tampered with and the signal is unlikely to cut out. However, a cellular connection is usually the most expensive option.
Common Home Security Equipment
While every home security provider offers unique packages and specialized equipment, there are many types of equipment that they all share. We’ve compiled a list of must-have home security basics below.
