Comcast turns your Xfinity WiFi into a home motion detector

Comcast is integrating WiFi-based motion detection into its Xfinity Shield home protection platform, leveraging routers and wireless devices to identify movement inside homes without requiring dedicated cameras or sensors. This feature uses existing network infrastructure to infer occupancy and activity patterns.

Why it matters: Homeowners and ISP customers should understand the privacy and security implications of passive motion detection on their networks, including data collection, retention, and potential attack surface expansion for an already-connected device.
