DIY home security vs. professionally installed systems: Pros and cons

As a homeowner, you have no shortage of things to worry about. Out of all of your responsibilities, the most important issue to tackle is home security. When it comes to protecting your home, you deserve the peace of mind that comes with a reliable home security system.

There are plenty of home security systems to choose from -- including professionally installed systems that offer live monitoring -- and DIY setups that are more budget-friendly. If you live in an area where frequent break-ins are a concern, you might be ready to invest in a great security system -- but if your biggest worry is keeping tabs on pets, visitors or rogue three-legged bears, you might not need all those bells and whistles. 

On the fence about whether to go the DIY route, or pay for a professionally installed home security system? Below, we break down the pros and cons for each, followed by a list some of the best home security systems of 2024.

Home security: DIY or go with the professionals?

"Selecting a trustworthy home security system requires careful consideration," says Toney Greer, CEO and founder of The Royal Society of the United States, a security company. "By recognizing signs that indicate the need for a security system, understanding the pros and cons of DIY versus professionally installed systems, exploring the market, you can make an informed decision."

If you're reading about increased crime in your area; own valuable possessions; or are a frequent traveler, it might be time to outfit your home with a security system. Read on for the pros and cons for either home security route, and then stick with us for a breakdown of the best and most reliable companies (and devices) in the market today.

Weighing the pros and cons of professionally installed systems

Let's start with the heavy hitters of home security. Companies like Vivint, ADT and SimpliSafe offer comprehensive packages that fully arm your home with security devices and all the best services. Some of these companies also offer DIY solutions, which are typically the cheaper option -- but you may sacrifice some great features if you go that route.

For example, Greer says, you'll miss out on expert installation, professional monitoring services for quick emergency responses, integration with smart home devices and the peace of mind that comes with professional equipment maintenance.

Professional installation can save you a lot of time and hassle, especially if you're looking to rig multiple indoor and outdoor devices. This perk is a bit of a double-edged sword though, given that installation fees typically start in the triple digits and go up from there (we saw an average of $150). 

A monitoring service is another reason to consider pros for home security. Professionally installed services typically come from big companies with a reliable network of professionals who keep tabs on your home all day -- if you're worried about getting caught off-guard with a DIY setup, this is the solution for you. The downside here: this type of service usually requires a multi-year contract, which can cost anywhere from $10 to $60 a month.

Reasons you might consider DIY system installation

"The biggest pro of DIY services, such as Ring and Nest, is the cost savings you receive for installing the system yourself," says Tim Reinemo, security professional and co-founder of Security Guards Only. "A professionally installed system will cost you more in flat installation rates and also can increase depending on the size of your property and what you want to be secured."

DIY solutions can be two to three times cheaper than professional security offered by big names like ADT and Vivint. If you know what you need -- and what you don't need -- the DIY route may be perfect. 

Security systems that you configure on your own often let you customize a system as you see fit. Want to add in an extra motion sensor or two? Not sure you need a wireless keypad and outdoor cameras? Most DIY solutions let you pick and choose individual devices to easily meet a variety of needs. 

One downside to DIY home security is the lack of features. Devices may be configured to work with other smart devices in your home, but full smart home integration is typically a perk reserved for professionally installed systems.

There is also the possibility that technical troubles could be a much bigger headache with DIY home security systems. After all, you won't have access to customer service or live monitoring professionals.

There are wireless and wired options, which means you don't have to worry about recharging any batteries if you don't want to.

Largest home security network: ADT

One of the most recognizable names in the world of home security is ADT.

Total prices start at around $600 for equipment plus professional installation. Live monitoring services can add on an additional $46 per month. You can access this through the ADT Control App (formerly ADT Pulse) -- not to be confused with the ADT+ App, which allows users to configure different ADT products (ideal for DIY installation).

Best home integration: Xfinity

This home security system by Comcast is perfect for homeowners less interested in a separate security system and more into full smart home integration. No, this doesn't mean connecting your outdoor security camera to your toaster or microwave. Instead, this means having multiple services (phone, internet, home security) installed and managed by the same company. 

This kind of convenience, when tacked onto the time and effort saved by letting professionals handle installation, makes Xfinity Home by Comcast a great choice for home security.

Base prices for the Xfinity Home bundle start at around $360. It includes one touchscreen controller, three door and window sensors (as well as one pet-friendly sensor), battery and cellular system backup, and a yard sign to let the neighborhood know your home is protected. You can also add additional devices of opt for the Complete or Ultimate Home System kits ($480 and $600, respectively), which come with additions such as a wireless keypad and more sensors.

Pros

• It offers easy integration with other Comcast devices and services.
• You can receive professional monitoring and installation services from trusted home security experts.
• The brand's base kit prices are cheaper than other professionally installed services, making for a good middle ground between DIY and professionally installed systems (budget-wise).

Cons

• Full smart home integration means you may be pushed to bundle security, internet, phone and TV services when making a purchase.

Professional services or DIY for your home security needs?

"When it comes to security, you really do get what you pay for," Reinemo says.

"Professional installation and outsourcing your monitoring will likely provide you with the best security in a logistical sense, as you are likely not going to be able to monitor and react efficiently to every notification that comes to your mobile device."

It's important to assess your home security needs before committing to a particular product or service. Professionally installed systems can be especially taxing on your personal finances thanks to installation fees and monthly charges for things like live monitoring services.

The price tag that comes with [professionally installed systems] makes sense," Reinemo continues. "However, if your main goal is to self-monitor for things other than security, such as your children coming and going and deliveries, a DIY security system may be all you need."
