Here’s what data Comcast says its motion-detecting routers collect

Comcast has launched Xfinity Shield, a new platform allowing customers to turn their routers into motion sensors using WiFi Motion, which detects activity via Wi-Fi signals. The feature has sparked privacy concerns among users due to a clause stating data might be shared if compelled by law and general distrust of Comcast. Comcast clarifies it collects motion activity records for up to 7 days within the Xfinity app, without using cameras or recording audio.
Why it matters
This raises significant questions about consumer privacy, data collection by internet service providers, and the potential for surveillance through smart home technology, impacting user trust and regulatory oversight.
Comcast announced a new platform this week called Xfinity Shield that includes the option to let customers turn their routers into motion sensors. Many people reacted with fear and anger.
“I am not enabling this. I am also seriously considering replacing my leased gateway with my own equipment, because a device I do not control sitting in my living room measuring the motion of my family is not a feature I asked for,” wrote one customer on the r/Comcast subreddit
Some concerns stem from a clause on the support page for the feature, called WiFi Motion, which says Comcast might share motion-sensing data without notifying you if compelled by law. Others appear to stem from a distrust of Comcast.
