The participation of major brands has validated and helped spur investment in the industry. Competition has gotten even fiercer as telecommunications and cable companies get in on the action. ATandT, Comcast, Time Warner Cable, and Verizon all offer home security solutions, many of which are bundled with other services such as cable and internet. From changing consumer demographics to tech advancements and telecoms' participation, an array of factors have aligned to make home security a massive industry.
