Experiencing a feeling of safety and security in your home is priceless, but there’s no need to spend too much to get it. The best professionally installed home security systems can turn your home into your castle, warning you of intruders when you are at home or away. The basic models include motion sensors and door sensors that are triggered when someone is in your home, a keypad that you use to enable the system and a hub that sends a signal to a monitoring service.

The more expensive models add features such as water sensors to monitor for broken pipes, sirens that sound to scare off intruders and fobs that can disable the system when you get home.

After researching a number of services, we’ve concluded that Vivint makes the best professionally installed home security system. Vivint Smart Home offers a lot of features, and customers also raved about the installers and the software that controls the system. However, it’s also one of the most expensive systems. Brinks Home Nest Secure is our favorite security system for homeowners on a budget, as you’ll spend the least over a two-year period for the base package, and it works with all of Google’s smart home devices

Bad news for Spectrum customers: Its parent company, Charter Communications, is shutting down its home security system on February 5. While the company is offering discounts on Abode and Ring smart home equipment, existing Spectrum equipment will not be compatible with other systems, according to news reports.

1. Vivint Smart Home

Best overall home security system

Key Specs: Base package includes 2 entry sensors, 1 motion sensor, keypad | Additional options: entry & motion sensors, carbon monoxide, smoke, water & flood sensors, cameras, video doorbell | Smart Home Support: Amazon Alexa, Google Assistant, Nest | Monitoring Contract: 3 years (with financing) | Monitoring Cost: $39.99 per month

The Vivint Smart Home system is one of the most sophisticated and customizable systems on offer. It’s also the most expensive. It offers a huge range of features, from the standard motion and entry sensors to indoor and outdoor cameras, plus video doorbell and extensive integration with smart home systems.

The Vivint starter system includes two entry sensors, one motion sensor and the control panel for $600. There’s also a $200 installation fee. Vivint is all about customizing the package, though, so it focuses on creating custom packages with other components. These aren’t cheap: The company's own video doorbell costs $250 (including installation), while a self-installed video doorbell from Ring will cost you about $180. Vivint offers financing, which allows you to spread the up-front cost over time with a multiple year-contract, and told us that most customers go with this option.

There are two levels for the monitoring service. The $39.99 monthly service is for a basic alarm system only, while adding a camera or doorbell adds another $5 a month. If you finance the system cost, while you won’t have any up-front costs, you will have rather large per-month payments. A system that included two entry sensors, one motion sensor, the video doorbell and an outside camera, for instance, would cost you about $69 a month over a two-year contract.

Both reviewers and customers praised the professional installation of the Vivint system and praised the way in which the installer will set up the smart home integration for you: No more fiddling with Alexa skills to get the two connected. The reviewers also praised the 7-inch touch-screen control panel that is the heart of the system, finding it easy to use on a daily basis.

2. Brinks Home Nest Secure

Best budget home security system

Key Specs: Base package includes 2 entry sensors, 2 motion sensors, keypad, 2 key fobs | Additional options: entry & motion sensors, siren, key fobs | Smart Home Support: Nest, Google Assistant | Monitoring Contract: month to month | Monitoring fee: $29.99 per month

The system from Brinks Home Security is built around the Nest Secure alarm system. Nest is now owned by Google, so it is no surprise that it integrates with Google’s own Assistant smart home system, which allows you to control the system with your voice. As well as two combined entry and motion sensors, this system includes two key fobs, which can disarm the system without the need of a key code when you tap on the keypad. That’s very useful if you are forgetful.

The Nest Secure system can also be installed by the user, although professional installation is available. It’s also wireless, so you don’t need to run wires from sensor to keypad. While the system is built by Nest, Brinks handles the monitoring and charges $29.99 a month. There is no long-term contract for this: It is all month to month.

Reviewers found that the Nest Secure system was easy to install, with the small sensors easily fitting into corners in hallways and on door frames. Reviewers also praised the ease of use of the key fobs and the ability to disable individual sensors, so you can do things like step out of the back door without setting off the alarm, while still being alerted if someone tries to break down the front door.

Note that this system is best used with other Nest devices, like the Nest Hello video doorbell and Nest Learning Thermostat, and that it doesn’t integrate with smart home systems other than Google Assistant.

3. ADT

Expensive monitoring, but low up-front cost

Key Specs: Package includes: 3 entry sensors, 1 motion sensor, siren, keypad, remote | Additional options: entry, motion, water and smoke sensors, cameras | Smart Home Support: : Z-Wave | Monitoring Contract: $28.99 for 3 years | Monitoring Fee: $47.99 per month

ADT is the 800-pound gorilla of the home security market. Its home security systems start at about $129 for installation and $44.99 a month, which includes two entry sensors, one motion sensor, a siren, keypad and remote. That’s the Traditional tier, which includes installation and remote monitoring.

If you want to integrate smart home features such as smart locks, you’ll need to go up to the Control tier, which costs $47.99 per month. This includes access to the ADT Pulse smartphone app, which is available for iOS and Android. This doesn’t work with smart home voice systems like Amazon Alexa or Google Assistant, though. That’s a bit more expensive than some, but it does include the cost of the equipment if you sign up for a three-year contract.

ADT's professional installation process is highly rated by both reviewers and customers. If you go with the higher tiers of service, the company also installs and connects the smart home devices and sets up the apps that control them.

While you are locked into a three-year contract to get the low up-front cost, ADT does offer a limited six-month money-back guarantee if the system doesn’t work for you. If you want to go the do-it-yourself route, ADT provides monitoring services for SimpliSafe’s security system.

Home security that resells through local companies

Key Specs: Base package includes: 3 door sensors, 1 motion sensor, siren, keypad | Additional options: entry, motion, water and smoke sensors, cameras | Smart Home Support: Z-Wave | Monitoring Contract: 5 years | Monthly Monitoring: $45 takes a slightly different approach than most other security companies: You don’t buy the system or service directly from the company. Instead, you buy a system through one of its resellers, who typically cover a specific region. makes the hardware and runs the monitoring service, but you don’t deal with them directly. We worked with a local dealer in Massachusetts to get the prices listed above, so your price might differ, based on location. 

Our local reseller offers several levels of service, each of which offers different features, but with a similar up-front cost of about $300. The basic system, as the name suggests, is the lowest level, with three door sensors, one motion sensor, plus the keypad and siren. The monitoring cost is $45 per month with a five-year contract. Smoke and carbon monoxide detectors can also be added, for an extra cost. The $55 Life Safety package adds in carbon monoxide and smoke sensors.

The system also integrates with smart home devices from other manufacturers, including SkyBell video doorbells, Arlo security cameras and the August Smart Lock Pro. These can be installed at the same time as the system or added in later on. That’s a nice change from systems like Vivint Smart Home, which only works with its own components. 

The installation service is provided by the local dealer, so the quality of service that you receive depends on the shop. However, many people prefer working with a local company rather than a large, faceless corporation. 


AT&T Digital Life

5. AT&T Digital Life

Bundle a home security system with your cable bill

Key Specs: Base package includes 6 entry sensors, 1 motion sensor, siren, keypad | Additional options: entry & motion sensors | Smart Home Support: Amazon Alexa, Z-Wave, AT&T Digital Life | Monitoring Contract: 2 years | Monitoring Fee: $39.99 per month (2-year contract)

The telecom behemoth AT&T offers a security system under its Digital Life banner. With a package price of $550 and a Monthly Monitoring fee of $39.99, it is one of the more expensive options that we researched.

There is also a two-year contract for the monitoring: Try and get out of that and you might be liable for more equipment costs. That’s because the base package includes quite a lot of equipment: two recessed contact sensors for doors or windows, four entry sensors for doors, one motion sensor, a siren and a keypad. Additional sensors are also available: additional motion sensors, contact and window sensors cost $19.99 and $9.99, respectively.

The system also requires professional installation, which is included in the price. An app, available for iOS and Android devices, allows you to remotely monitor the system.

6. XFinity Home Security Plan

Cable TV, internet, phone, and home security integrated

Key Specs: Base package includes 3 entry sensors, 1 motion sensor, keypad | Additional options: entry & motion sensors, smoke detector, camera, thermostat | Smart Home Support: Xfinity X1, Z-Wave | Monitoring Contract: 3 years (with financing) | Monitoring Fee: $39.95 per month (2-year contract)

Through Xfinity, Comcast offers home security mainly as an additional service for its cable TV customers, but it is also available to anyone in its coverage area. The base home system that the company offers includes a decent selection of features, with the entry sensors, one motion sensor and a touch-screen control center for $360.  

For larger houses, there is a $480 option that increases the number of door sensors to five and adds in a wireless camera. There is also an ultimate kit that covers 10 doors and includes two cameras for $600. Xfinity also offers no-interest, 24-month financing for the system cost, so you can spread the cost of either system over time when you sign up for the two-year monitoring contract. Monitoring is provided by COPS Monitoring.

Additional sensors can also be added at a fairly low cost, like a $70 smoke detector, additional motion detectors for $40 and a $120 camera that can be used indoors or outside. If you have an Xfinity X1 cable TV box, you can control the system from there and watch live video from the camera.

The system can also control a wide range of smart home devices that are compatible with Z-Wave, such as smart locks, garage door openers and others, but that doesn’t work both ways: You can’t control the Xfinity system from Amazon Alexa or Google Home devices or view the camera video outside of the Xfinity Home app.

Xfinity has a poor reputation for customer support, and the customer feedback on its home security service doesn’t seem to be any different, with customers complaining of long wait times and a lack of response to email questions.

How much does professional home security cost?

The price of these systems varies widely, from a minimum of $30 to $50 per month for a basic system with a couple of door sensors and a motion sensor. However, additional sensors and things such as cameras will increase the price, often significantly. Part of the reason for that range is that some companies allow you to spread the cost of the hardware over the term of the contract, so you have little or no up-front cost, but a higher per-month cost.

As most of these systems also require you to sign up for a long-term monitoring contract, the monthly plan isn't a bad option for spreading the cost. However, make sure that you understand what happens if you move or decide you don’t want the system: In that case, some companies will charge a cancellation fee or demand that you pay for the balance of the contract.

Professional home security systems vs. DIY home security systems

All of the systems in this article are installed by professionals, which are good for those who don't have the time, patience, or expertise to install all the requisite sensors and equipment. Since the systems compared here are all installed by the company or another professional installer, all you need to do is open the door to let them in and pay the bill. However, in general, professionally installed systems cost more, and you usually have to also sign up for a monitoring plan.
