Comcast Adds Motion Detection to Wireless Routers, Raising Privacy and Security Questions

Comcast has introduced motion detection capabilities in its wireless routers, using Wi-Fi signals to detect movement near connected devices and sending push notifications to users. The feature, accessible via the Xfinity app, offers different sensitivity settings for home, sleep, and away modes. Comcast acknowledges limitations due to home size, layout, and building materials, and does not guarantee performance. This development expands the use of consumer networking hardware for ambient sensing, raising potential privacy and cybersecurity concerns.
