Security system installation: DIY versus professional

How much does security system installation cost?

Professional installation of a security system usually costs between $99 and $199, depending on the home security company and the complexity of the system. This estimate only includes installation, not the cost of the equipment or monitoring. Some companies don't require upfront payment for equipment and instead spread out the cost over the life of the contract. Installation costs are typically paid upfront.

While DIY installation is free (because you do it yourself), most companies who offer this installation model require you to purchase equipment upfront. The full cost of a security system may range from $20 to more than $1,000, depending on the type and number of devices you opt for. Financing options are also available, so you can break up the cost into affordable monthly payments.

How long does it take to install a security system?

Both DIY and professional installation can take as little as 30 minutes or as long as a few hours. Longer installations typically include complicated equipment, such as wall-mounted control panels, thermostats, locks or security cameras. Meanwhile, systems that are designed for self-installation are typically simpler and wireless for your convenience.

Installing a single security device (window sensor, camera, etc.) may take about 10 minutes.

If you’re thinking about a system with DIY installation, consider how long it would take you to install each component and how much that time is worth to you. (Keep in mind installing a single device can take around 10 minutes.)

If you don't mind sacrificing a weekend afternoon, DIY installation may be right for you. However, those with busy schedules may find professional installation a better option.

If you do the installation yourself, you aren’t on your own. Home security companies provide helpful installation guides, troubleshooting tips and tech support if you're stuck on any part of the process. If you try to self-install and find it isn't for you, you usually still have the option to pay for professional setup.

Monitoring your home security system

Whether you install a security system yourself or pay for professional installation, you can sign up for professional monitoring services. These monitoring services rely on Wi-Fi, cellular networks or landlines to transmit data to the monitoring company in the event of an emergency. Most wireless systems even have backup batteries or networks in case your primary service is disconnected.

With DIY systems, you may also have the option to self-monitor your home instead of paying a monthly monitoring fee. With this option, the company won't actively monitor your home or contact emergency services on your behalf — instead, you'll receive alerts on your phone if anything triggers your sensors, cameras or other devices.

This is ideal if you want to spend less and be in complete control, though some companies still charge a fee for self-monitoring, especially if you want to record video.

Pros and cons of DIY installation

There are, of course, upsides and downsides to DIY home security installation.

Benefits of DIY installation

DIY installation is typically more affordable — and more flexible — than professional installation.

• Ability to upscale: DIY systems let you start small and add components according to your needs. This is a good choice if you’re unsure what kind of system you want and don’t want to spend a lot of money on something you won’t use.
• Best for small homes: DIY installation is best for smaller homes or apartments because there’s less area to cover and less equipment needed. Most newer systems are also wireless, and in a smaller space, you’re less likely to lose a signal.
• Ease of transfer: DIY systems are much easier to transfer from one home to another. If you rent or move frequently, you should opt for a DIY system.
• Lower cost: DIY systems are almost always cheaper than ones that are professionally installed.

Drawbacks of DIY installation

The main drawback to installing a home security system yourself: more work and responsibility.

• Requires some technical knowledge: If you’re not tech-inclined, DIY systems may be more trouble than they’re worth. The initial installation and connection should be fairly straightforward but may require tinkering and maintenance down the road.
  
  SafeWise.com reporter Rebecca Edwards told us: “While most of these systems are super simple, I’ve run into enough problems with programming equipment, setting the right language and putting things in the right places. You can run into a lot of trial and error, especially if you’re trying to avoid pets setting off alerts every time they move or have interference from things like tree branches in front of motion-sensor cameras.”
• Self-monitoring: Some DIY systems require a fee for self-monitoring, even though you’re doing all the work.
• Responsibility for repairs and replacement: While some DIY companies provide online or telephone help, you usually aren’t able to call a technician to fix equipment on-site.

Pros and cons of professional installation

Now let’s look at the advantages and drawbacks of professional installation.

Benefits of professional installation

The main perk of professional installation is the technicians’ know-how — and less hassle for you.

• Customization for large spaces: Professionals can design a system specifically for your home and ensure all areas are properly covered. These systems are better for larger homes that require many interconnected components over multiple floors.
• 24/7 monitoring: Most professional systems offer monitoring services for a monthly fee, while not every DIY company does. Professional monitoring includes 24/7 response in case an alarm is triggered in your home.
• Low hassle: With a professionally installed system, all you have to do is choose the level of protection you want, and the company takes care of setting it up. If you have future problems with equipment, a technician can visit your home to fix the problem.
• Integration with existing systems: Professionals can help integrate your new security system with your existing smart devices, like smoke and carbon dioxide detectors and thermostats.

Drawbacks of professional installation

The main drawback to having your system professionally installed is the cost, although some companies may offer free professional installation when you purchase equipment.

• Higher price: Professionally installed systems are almost always more expensive than DIY systems, so if you’re on a budget, consider DIY.
• Harder to transfer: Since many professionally installed systems are designed especially for the home you’re in, they can be hard to transfer to another house.
• May require a long contract: Although companies are starting to move away from lengthy contracts, there are still some that want you to sign a several-year service contract.
• Waiting: With pro installation, you have the inconvenience of waiting for an installation technician to get to your home and complete the job. You might have to miss a day of work while your system is installed.

Is having a professional install your home security system worth the cost?

This depends on how big your home is and the level of coverage you want. If you live in a smaller home or apartment, a DIY system is probably the right choice. If you live in a large, multistory house, it’s likely worth the extra cost to have a professional customize your installation for your property.

“Anyone who doesn’t dig DIY, and those who are really concerned about getting their system set up to best cover all security vulnerabilities in their home” should go with professional installation, Edwards said. “Pro installation can save backache, headache and worry. Pro installers test everything right there with you, explain how it all works, and leave you feeling really confident — not just in the system, but in your ability to use it.”
