DIY vs. Professional Security System: What’s the Difference?

One of the first decisions you make when buying a security system is deciding whether you want to install it yourself or have it professionally installed by a company. But did you know that one of the other key decisions in deciding which security system is best suited for your property is whether you want a DIY or a professional security system? Although not many know the difference between the two, this decision is a necessary one to make when it comes to finding the security system that works best for you. So, a DIY vs. professional security system—what’s the difference? Keep reading to find out more.

DIY Home Security System

A DIY home security system has a few key differences. For one, they allow you to build your kit before purchasing the actual system, giving you the freedom to add or remove whichever services needed. In addition to this, the customer would be responsible for the installation process, unlike with most professional security systems which are often installed by the company it was purchased from. However, the installation process typically isn’t too complex.

Additionally, one peculiar feature about DIY systems is that, oftentimes, you can get professional monitoring as an optional add-on; however, the prices for this service varies with each company.

A professionally installed security system has many benefits

Professional Installation & Monitoring

While a DIY security system can offer many beneficial features, a professional system has additional benefits made to fit the right home. Above everything, the biggest benefit that comes with a professional security system is the painless effort that comes with installing it. These systems typically come as pre established kits that are often offered in tiers. The base of the system offers common devices such as alarms, door/window sensors, and control panels, while higher-tier kits add additional features that include thermostats, fire alarms, bells, whistles, etc. For many companies—like Mesa Alarm Systems—that offer professional systems, installation can be acquired at no additional cost. The experts set up the system for you, activate it, show you how it works, and monitor it for you.

An additional benefit of a professional system is that it integrates nicely with its devices. Unlike a DIY system, the devices included in your system aren’t from multiple brands that may not work with your other smart gadgets, allowing them to work consistently and easily across the board.

What Are the Pros and Cons of Each?

Although there are many advantages to both of these types of systems, choosing the right one depends solely on your needs for a security system. Which one guarantees the most security for your residence? Differentiating the pros and cons between the two is a starting point.

DIY Home Security Systems:


  • Gives you the option to start gradually and add pieces as needed
  • Easier to transplant from one home to another
  • Doesn’t require professional monitoring (although it is recommended)


  • Harder to install in multilevel dwellings
  • Harder to maintain
  • If something goes wrong, there is no one to call
  • Self-monitoring is less effective than professional monitoring (however, some DIY systems do offer professional monitoring for an additional fee)

A large benefit that comes with a DIY home security system is that you do not need to buy the complete system all at once. Instead, you can purchase what you need or can afford at the moment, then add more later. DIY home security systems are highly recommended for those who are tech-savvy to properly install, monitor, and maintain. However, if you are not proficient in the use of modern technology, getting accustomed to security camera installation and operation is the first step in determining whether a DIY security system may be the better choice for your residence.

Professional Installed Home Security Systems:


  • Customizable to your specific home needs and circumstances
  • Higher quality which makes for more reliable monitoring
  • Easier integration of sensors and other add-on equipment


  • More expensive than a comparable DIY system—especially with professional monitoring
  • Can overkill apartments or smaller areas
  • Difficult to transfer the system from one home to another

For effective security in a larger home, a professionally installed home security system is your best bet. In general, a professional system is more effective, easier to maintain, and easier to integrate with additional security devices, including smoke, carbon monoxide, and flood detectors, as well as smart thermostats, fire alarm systems, and more. Additionally, your system can be customized by an installer to fit your specific needs.
