But the long standing ADT may be a better option for you if you aren’t interested in doing the research and experimentation to arrive at your perfectly tailored set of devices. While Xfinity offers a single plan, then a range of choose your own adventure add ons, ADT gives you five already fleshed out plan options. You can shop based on your preferred security style — from basic to extensive — and the price you’re willing to pay. This method also puts you in a better position to understand your final costs, whereas picking out security devices one by one can add up quickly, with lingering side effects on your monthly bill. For example, when you choose to record video with Xfinity, the additional price is levied per camera. Vivint wears the crown for top of the line home security automation, but with Xfinity’s in house line up — plus extensive partner brands — the Comcast offshoot gives Vivint a run for its money. If you are keen on outfitting your home with smart tech, both companies deserve consideration. The longer warranty with Vivint could give you more peace of mind, as does the possibility of paying month to month rather than signing up for a multi year contract with Xfinity. On the other hand, you could save some money with Xfinity thanks to their first year promotional rate, plus the opportunity to bundle if you go through Xfinity for TV or internet. Like many other big cable corporations, Comcast broached home security in order to offer customers another broadband dependent service that could be easily bundled with TV and internet. The Comcast telecom empire entered the home security space in 2011.
