Power’s 2018 customer satisfaction survey, Xfinity falls below the industry average. Whereas Brinks Home Security garnered five out of five power circles J. D. Power’s proprietary ranking scheme and ADT and Vivint both got four out of five, Xfinity only claimed two. The origin of customer dissatisfaction may be the number of surprise fees, like paying around $100 for installation and several hundred for cancellation, as well as the expense of shopping for a la carte devices. There’s also the additional monthly bills that aren’t accounted for in Xfinity Home Security’s advertising: If you want your security videos to be able to record, rewind, and review up to ten days of footage, you’ll have to pay $10 per month per camera. Perhaps the two most commonly seen yard signs are pretty comparable when it comes to pricing, installation, and monitoring. 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.
