Let's Find The Right Home Security Systems Service For You

Pros / Xfinity Home supports third-party smart home devices from the likes of Nest, August and Lutron.

Cons / You can't get customer support over email.

 Verdict / Xfinity Home's lifetime warranty, reasonable contract terms and good customer service make it a worthwhile option for a home security system.

Xfinity, the trademark name for Comcast Cable Systems, has moved beyond its cable TV and internet endeavors into home security with its Xfinity Home offerings. Xfinity Home offers 24-hour monitoring that connects to the monitoring station via your internet provider – and it does not have to be Xfinity. The system also has a cellular backup in case the internet goes down.

When you sign up for service, your contract runs two years and renews on a monthly basis after that. If you cancel early, it will cost you up to $660 – Comcast reduces this sum by $30 per month for every month you are an Xfinity Home customer. Considering that the monthly monitoring fees are $39.95, this comes out to around 75 percent of the remaining balance. These are among the most competitive cancellation fees among the companies in our review, which are usually between 75 and 100 percent. You can return your equipment and cancel without fees within 30 days of signing your contract.

Xfinity Home equipment requires professional installation. A company representative will assess your home and offer recommendations for customizing the system, including home-automation capabilities you may want to consider. You also get a tutorial on using your system when you first get it.

Once your house is outfitted, it is monitored around the clock by a security station. If a device detects something unusual, you will get text and email alerts. You do not need to worry if the electrical power goes out since you have cellular and battery backup protection.

When you sign up, you get a touchscreen control panel, three door and window sensors, a wireless keypad, and a motion sensor as standard equipment. This equipment package also comes with six window decals and a yard sign. The equipment is covered by a lifetime warranty.

You can add other equipment to your system, such as a remote key fob, fire and carbon monoxide detectors, home automation controls for lights and appliances as well as a thermostat and indoor/outdoor surveillance cameras. One of the things we noticed about Xfinity Home's security cameras is that your monthly fees don't go up when you add a camera to your system, you only pay the for the camera itself; this is rare among home security systems.

One of Xfinity Home's best features is its compatibility with third-party smart home devices such as the August Smart Lock, Chamberlain garage door openers, Lutron lighting and the Nest Learning Thermostat, among others. Very few home security systems offer this kind of compatibility with popular consumer devices, so Xfinity's choice to support them is noteworthy.

Xfinity Home offers fine customer service via live chat and phone, and our contacts with the company have been positive. On social media, you can contact ComcastCares, a dedicated customer service Twitter profile, or Xfinity on Facebook for assistance. You do not get email communication; Xfinity is one of three companies in our review without it.

Xfinity Home offers a useful package of security equipment for the money. You get the benefit of a lifetime warranty on the equipment, and the customer service is pretty good, especially on social media. As with all systems, the costs could add up if you buy additional security devices to flesh out what Xfinity Home offers, but it's still worth considering, especially if you want to bundle it with other Xfinity services.
