The Internet at Your Perimeter: Comcast's Wi Fi Surveillance State The latest innovation from cable giant Comcast is Xfinity Shield, a home security system that combines home, family, and cybersecurity protection in a single app.
At its center is Wi Fi, which the company uses to detect motion within homes. Comcast's Wi Fi Motion feature works by monitoring changes in radio frequency signals between the Xfinity Gateway and connected devices.
This technology isn't new – it has been used in various forms for years – but its integration into a mainstream home security platform is noteworthy.
