Overview
- Comcast announced the rollout on Tuesday, August 18, 2026, making Xfinity Shield available to Xfinity Internet customers and offering WiFi Motion as an opt‑in feature for advanced gateways (XB7 and newer).
- WiFi Motion converts the radio link between the Xfinity Gateway and stationary Wi‑Fi devices into virtual motion sensors by detecting disruptions in RF signals and then sending app notifications without recording video or identifying people.
- Customers must opt in and can choose sensitivity and mode settings; Comcast warns the system can misread small pets or adjacent building movement and lists specific compatible gateway models in support documents.
- Comcast discloses in its support materials that data generated by WiFi Motion may be shared with third parties for law enforcement requests, court orders, or disputes, while retention periods and exact disclosure thresholds are not fully specified publicly.
- Xfinity Shield includes a free baseline of cybersecurity and family controls and a paid Shield Select tier for $15 per month that adds an indoor camera, door/window sensors, cloud video storage, and 24/7 urgent response; Comcast says the move aims to deepen broadband customer engagement and builds on multi‑year algorithm work and a 2023 patent filing for RF presence detection.
