What Are the Different Types of Home Security Systems?

Quick answer

Home security systems differ by installation method and monitoring method. For each method, you can go either the DIY or the professional route.

To some degree, you can mix and match installation and monitoring methods. Depending on the company, you may get a professionally monitored system with either DIY or professional installation, but generally you’ll have to install your own equipment if you want to self-monitor.

ASL Insider Tip

If you want to save money, both DIY installation and DIY monitoring are cheaper than their professional counterparts. Professional installation and monitoring, on the other hand, require less effort, and professional monitoring in particular is safer.

Types of home security systems

When you consider what type of home security system to get, you’re primarily making two decisions: whether you want to install your own system or get it professionally installed, and whether you want to monitor your own system or have it professionally monitored.

Keep in mind that what you decide will limit your security company choices. If you get professional installation, for example, you pretty much have to get professional monitoring. You’ll need to decide what your priorities are and look for home security companies that match your preferences.

To make that process easier, we’ve broken down what you need to know about installation and monitoring options. Keep reading to find out what type of home security system is right for you.

Installation options

installing home securityIf you want to secure your home, you’ll start by installing equipment. This includes things like your control panel, cameras, glass sensors, and motion detectors. You have the choice to install this equipment yourself (DIY installation) or get it professionally installed.

DIY installation


  • No installation fees
  • Easy setup
  • Clear instructions and web/phone support


  • Limited availability with some professionally monitored systems
  • More time and effort than professionally installed equipment

You may ask yourself, “Why wouldn’t I want a professional who knows what they’re doing to install my system?” At first glance, DIY installation often feels intimidating, and you might even worry it leads to a less secure home. Well, neither of those notions is exactly true.

Most people choose DIY installation to save money. When you put in your own equipment, you don’t have to pay any installation fees, which is an easy way to lower the the cost of security systems. Plus, you don’t need to take a day off work to let someone into your home to drill holes and run wires through your walls.

Fortunately, DIY installation is doable for most people. Most companies offer clear, thorough instructions on how to install your equipment. In some cases, it’s as simple as sticking self-adhering sensors to a wall. If you run into snags, you can always contact customer service for help.

Like we mentioned earlier, many companies that offer DIY installation also offer professional monitoring. You certainly can choose a system that’s both DIY install and DIY monitoring, but the two are not synonymous. Now hold that thought—we’ll get back to monitoring options in a moment.

In short, DIY installation can be a more affordable option.

Professional installation


  • Hands-off approach
  • Professional knowledge in placement and installation


  • Extra fees in some cases
  • Availability with professional monitoring only

If DIY installation sounds too hard or time-consuming, professional installation might work better for you. Your alarm company of choice will supply the equipment and put it in, meaning you have more time to spend doing what you want.

While you can safely and securely install your own equipment, you might rest easier knowing a trained professional did the work. Your security cameras and motion sensors will be where they should be and working well, so you won’t ever have to second-guess your own skills—a welcome respite for the less technologically savvy among us.

Of course, professional installation may cost extra. Pro installation often comes with a installation fee of around $50–$100, though not always—several of the best systems with professional installation don’t have an installation fee. Even if you choose a system with an installation fee, the extra cost may be well worth the time and effort saved.

If you decide to go with a professional installation, keep in mind that you’ll need professional monitoring as well. With a DIY install, you may have choices for both self- and professional monitoring, but pretty much all companies that offer professional installation require you to use professional monitoring. Of course, we strongly recommend professional monitoring, so we don’t think this should keep you from choosing a pro install.

In short, professional installation costs a bit more than a DIY install, but it saves you time and energy.

In short, professional installation costs a bit more than a DIY install, but it saves you time and energy. It also guarantees you’ll get professional expertise on everything from installation to monitoring.

Monitoring options

In virtually all cases, if you choose professional installation, you also have to choose professional monitoring. Some DIY install companies offer only professional monitoring, and others offer only self-monitoring—though companies like SimpliSafe offer both options. Let’s break down each option a bit more.

DIY monitoring


  • Lower price—no monthly fees
  • No contract to worry about


  • Pressure to notice and respond to notifications
  • More risk than with professional monitoring

With DIY home security, not only will you save on installation fees, but you can also save on monthly monitoring fees.

However, those monetary savings come with a cost. Unmonitored security systems put the burden of security on you. It’s up to you and you alone to react to alerts from your system. Of course, that’s not always possible.

What if you’re asleep when your alarm system sends an alert to your phone? What if you’re in a meeting without your phone? What if you don’t have reception? Or, even worse, what do you do if an intruder is already in your home? How quickly can you respond and get help? These questions aren’t meant to scare you but to help you understand the very real downsides of self-monitoring.

Even with these drawbacks, a self-monitored security system is better than no security system. If you want to save money and you understand the potential problems, DIY monitoring could work for you. If you’d prefer more security, think about choosing professional monitoring.

Professional monitoring


  • More security
  • Someone always ready to respond to an emergency


  • Monthly fees and contracts

With professional monitoring, you pay a monthly fee to ensure that someone responds in case of an emergency. That means that if your alarm goes off, your security company responds 24/7. If you choose a company that offers Crash and Smash protection, it will be alerted to an incident even if a burglar quickly destroys your control panel.

The bottom line is that professional monitoring offers greater security. It does cost more than DIY monitoring, but you’re paying for a valuable, even life-saving service. Whether your motion detectors or smoke detectors go off, a monitoring company will have your back.
