Just joined the over 1 million strong Xfinity Home Family and looking for some added help?

Well, you’re most certainly in the right hands. Because your Xfinity Home services and products carry the mark of Comcast’s legacy as an industry leader when it comes to advanced innovation. The xFi Gateway is one example of that. So is your X1 in-home entertainment system. And the Xfinity Home smart security system.

Speaking of which, you’re at the right place too. Because our article today walks you through the different ways Xfinity gives you to manage your smart home security. Read on and help yourself get comfortable with your new Xfinity Home security system powered by Xfinity Internet.  

Ways to Manage your Xfinity Home security 

The Xfinity Home security products introduce a totally new level of ease, flexibility, and mobility to your home safety regime. Quite like the Xfinity Internet service which allows you to enjoy the advantages of the xFi Gateway, and the X1 TV service which allows you to watch Cable in a contemporary way.

How many ways you can manage your Xfinity Home security depends on the system you are using and the service plan you are on. For instance, if you have a Base System installed, the wireless keypad option would not apply to you. As that is included with the Complete and Ultimate Home Systems. And if you happen to be on the Xfinity Self Protection plan, you will be using the Xfinity app for remote control instead of the Xfinity Home app. Also controlling via X1 is possible only if you are also subscribed to the Xfinity Cable TV service.

All in all, when you pick one of the more complete systems coupled with the Pro Protection or Pro Protection Plus plan, you get to maximize the benefits of your home security subscription. And if you are signed up for Xfinity TV, it only adds to the level of convenience Xfinity Home affords you.

Here are 5 ways you can arm or disarm your system, monitor system status, review the latest activity, and view the live video feed. You will find more than one way to manage your Xfinity Home security from anywhere via any device, no matter which system or plan you are on.

The Xfinity Home app 

The Xfinity Home App comes free with Xfinity Home security. You can download it on your iPhone or Android device. When setting up the application will ask for permission to include the Xfinity Home SMS and Professional Monitoring Station phone numbers to the contacts on your device. This allows your device to quickly recognize text messages received if the Xfinity alarm security system goes off. So you need to okay the request.   

Sign in using your Xfinity username and password and set up your Touch ID, fingerprint ID, or face ID, whichever may be applicable. 

Xfinity X1  

When you are an Xfinity X1 subscriber, you can use the award-winning Xfinity Voice Remote to manage your home security. And access the Xfinity Home app on your TV. With the Xfinity Home app on X1, you can arm or disarm your home security system, view videos from connected cameras, or browse through event history. The Voice Remote makes it so much easier to manage Xfinity Home settings.  

The best part is you never have to leave your couch. Say it to the remote and sit back as it tunes you into the live video feed from your backyard camera. 

Online user portal 

If you prefer to use your computer to access the Xfinity Home security system while at work, you have nothing to worry about. Log into your Xfinity account and manage your account settings as well as your system in more detail. Manage rules, cameras, or devices, check system alerts, view events and notifications, change your settings and also get support. You can also update emergency contacts. And personalize Keypad Codes for family and friends or anyone else who may need access.  

You can access the online portal right here.  

Wireless keypad 

Your Xfinity Home security system may come with a wireless keypad. It is an unwired remote kind of keypad that you can keep anywhere in your house. The wireless keypad allows you to arm or disarm the system from anywhere within your house. 

It makes things simpler because you don’t have to walk over to a wired controller affixed to one spot every time you need to make a change in the status of your Xfinity alarm security. You can keep the wireless keypad in your room and control your security system right from your bed!

Touchscreen controller 

The touchscreen controller included with your Xfinity Home security system is usually mounted on a  wall at a convenient spot in the main entrance area. This is the hub where it all comes together as it communicates directly with all the devices integrated into your home security as well as the Professional Monitoring Station. Hence, this controller should not be tampered with or moved around from its initial install position. Doing so can interrupt the connectivity with the Monitoring Station.  

The touchscreen controller allows you to manage all system settings, view current security status, arm and disarm your system, send an emergency alarm, view sensor activity or live camera feed, manage your Keypad Codes, and do more.

How the Pro Monitored Xfinity Home security solution works

With an Xfinity Home security package that includes pro monitoring, you can count on the award-winning Monitoring Stations and fast response times. Help is never too far away!  

When an alarm is triggered based on your settings, you receive a notification via email, text, or the app. If you know it to be a false alarm, you can cancel it immediately using your 4 digit Master Keypad Code. Once the alarm is canceled, you will not receive a call from Xfinity Home.

In the unfortunate event, the alarm is triggered due to a legit threat or security breach – things are slightly different. The Professional Monitoring Station will attempt to reach you via phone. If they fail to contact you, they will attempt to reach the emergency verification contacts on your list, both before and after concerned authorities are notified.  


In a market full of home security systems, Xfinity Home powered by Xfinity Internet is a breath of fresh air. Managing your Xfinity Home security is pretty simple once you get used to how your setup works. You are always on top of things with ready access at your fingertips, no matter where you are, while pro monitoring ensures any threat is met with a quick response.

Frequently Asked Questions (FAQs)

How to replace the batteries in the window sensors? 

Disarm your Xfinity Home security system and put it in test mode before you start to replace the batteries. Then remove the cover from the sensor to expose the larger compartment with the battery in it. Make a note of the positive and negative on the batteries already in the sensor. Replace the old ones, and place the cover back on the sensor. You can ignore the home system alert which tells you the sensor is being tampered with. The alert will automatically clear out when you are done replacing the batteries.  

What is the exit delay on my Arm Away mode? 

The Exit Delay comes with your Arm Away mode and allows you to leave the premises before it activates your security system. If you activate the Away mode and no one leaves the house using a monitored door, the system automatically switches to Stay mode.

What is the Arm Night mode and how does it work? 

The Arm Night mode is perfect for when you are home and asleep. Xfinity Home security features are activated just like the Away mode, but motion sensors do not get activated unless customized to be. 

By default motion sensors that are inactive in the Arm, Night mode is in the area where there may be activity at night time. A motion sensor active in the Arm Night mode will immediately trigger an alarm if crossed, which is why these must be installed in areas such as the attic, garage, or basement.
