Comcast launched its newest in-home service endeavor Wednesday in Chicago with Xfinity Home, a package centered around wireless home security offerings.

The move, which had been tested in several cities around the country and will be rolled out throughout the year, is part of a longer-range plan for Comcast, in which it takes more and more advantage of the infrastructure it already has in place to pipe data into millions of customers’ homes nationwide. For instance, a heftier version of the Xfinity Home package includes options to have Comcast remotely manage your lights and thermostat, too.

But the already-in-place infrastructure doesn’t just end with coax cables.

“We think we can get a share of that [home security market], but we also think we can expand the market,” Comcast chief executive Neil Smith told the Chicago Tribune. “Some of the advantages we have going to market is we have an existing customer base and sales force. We have technicians … and existing call center operations. We think we can leverage those.”

With a staff of field techs at the ready — already outfitted with equipment and vans, and supported by existing call centers and dispatching centers — Comcast has a leg-up on many of the home-security services on the market.

And besides whatever revenue Xfinity Home may ultimately bring in, having service techs out there installing these products in customers’ homes presents all sorts of upselling opportunities, especially for a company that’s rapidly diversifying its services.
