Cameras are the go-to option for many consumers for home security but bring up everyday privacy concerns, which is something Comcast Xfinity Shield approaches head-on. The home security platform takes a combinational approach that incorporates home, family and cybersecurity into a single app where WiFi remains the primary technology for performance.
The platform utilizes the WiFi Motion technology that leverages the connection between devices and an Xfinity Gateway to detect for any radio frequency changes. This indicates motion in the home and will trigger an alert for the administrator. The main advantage of the feature is its ability to offer an additional layer of home security awareness without the need for video recording, image capture or individual identification. The feature is opt-in to let subscribers use it at their discretion.
