Comcast is adding motion detection to millions of routers, and I’m worried it’s a privacy nightmare
Comcast’s Xfinity routers can sense people’s presence in your home, but many users are worried.
Comcast is introducing a new feature called WiFi Motion to its Xfinity internet services, which detects changes in Wi-Fi signals to sense the presence of people in the home. Once activated, users receive notifications in the Xfinity app when someone is in their house. While Xfinity claims it provides basic security, the move has sparked privacy concerns among users.
Critics liken it to controversial numberplate-recognition cameras, and some worry that the data could be sold or used for malicious purposes. The privacy implications are significant, as millions of users may unknowingly have their movement data collected and potentially shared with third parties. Furthermore, there are no clear answers regarding how long the data is retained, who can access it, and what safeguards are in place.
Critics also fear that this widespread data collection could make routers vulnerable to hacks, allowing intruders to disable security systems for burglary opportunities. While Comcast claims the feature is opt-in, users are concerned about the possibility of automatic enrollment in future updates. As privacy concerns grow, users are advised to consider alternative router options or invest in dedicated home security cameras for better control over their data.
