WiFi routers now tracking motion: Xfinity’s new feature sparks privacy concerns

Since the start of the year, Xfinity, a major Comcast brand for telecommunication services in America, has been notifying users about a useful new feature, WiFi Motion. It allows turning internet devices into motion sensors that monitor movement at home.

At no extra cost, the Xfinity app allows users to select up to three WiFi-connected devices and will alert users if motion has been detected between them. Once set up, the printer, smart fridge, an Xbox, or any other IoT device will also turn into a motion sensor.

“With high sensitivity, you may detect small movements like the wave of a hand,” the support page states.
