Read it at the original source: ## Questions this post answers ### What is Comcast's Wi-Fi Motion feature and which routers support it? Wi-Fi Motion is a free, opt-in feature from Comcast that turns Xfinity gateways into motion sensors by detecting interruptions to the Wi-Fi signal, sending notifications through the Xfinity app when activity is detected at home. It works on advanced Xfinity gateways starting with the XB7 model and newer, and is intended for basic home security and motion detection. _Homeowners weighing smart-home security features can track privacy trade-offs like this on daily.dev._ ### Can Comcast share Wi-Fi Motion data with law enforcement without telling me? Yes, according to Comcast's own support documentation, it may disclose information generated by Wi-Fi Motion usage to third parties without further notice to the customer, in connection with any law enforcement investigation or proceeding, a dispute involving Comcast, or a court order or subpoena. _Privacy-conscious readers evaluating connected-home features can follow stories like this on daily.dev._ ## Similar posts on daily.dev - [Schneier on Security](https://daily.dev/posts/schneier-on-security-0hjgtapw6) · Schneier on Security · 0 upvotes · 0 comments - [Comcast gives its Wi-Fi motion detector a security makeover](https://daily.dev/posts/comcast-gives-its-wi-fi-motion-detector-a-security-makeover-obtsl2qpw) · The Register · 0 upvotes · 0 comments - [I turned Wi-Fi signal into a home motion sensor using an ESP32, and it now controls my smart devices](https://daily.dev/posts/i-turned-wi-fi-signal-into-a-home-motion-sensor-using-an-esp32-and-it-now-controls-my-smart-devices-fdaqhj3zn) · XDA Developers · 2 upvotes · 0 comments - [Motion detection system based on Wi-Fi spectre analysis \(CSI\), with Home Assistant integration.](https://daily.dev/posts/motion-detection-system-based-on-wi-fi-spectre-analysis-csi-with-home-assistant-integration--qo37bhgwk) · Hacker News · 2 upvotes · 0 comments --- Tags: [#privacy](https://daily.dev/tags/privacy), [#iot](https://daily.dev/tags/iot) [View this post on daily.dev](https://daily.dev/posts/comcast-adds-motion-sensing-to-millions-of-its-newer-routers-with-a-privacy-catch-w0aelfnak) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Comcast adds motion sensing to millions of its newer routers, with a privacy catch","url":"https://daily.dev/posts/comcast-adds-motion-sensing-to-millions-of-its-newer-routers-with-a-privacy-catch-w0aelfnak","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/comcast-adds-motion-sensing-to-millions-of-its-newer-routers-with-a-privacy-catch-w0aelfnak"},"datePublished":"2026-08-18T16:40:51.103Z","dateModified":"2026-08-20T12:19:17.500Z","description":"Comcast has launched Wi-Fi Motion, a free opt-in feature for its newer Xfinity gateways (XB7 and later) that detects motion inside a home by monitoring Wi-Fi...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/03084a5a8572eeb3e4dd3829ce31c7e1?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/03084a5a8572eeb3e4dd3829ce31c7e1?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"TechCrunch","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"TechCrunch","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tc","url":"https://daily.dev/sources/tc"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/comcast-adds-motion-sensing-to-millions-of-its-newer-routers-with-a-privacy-catch-w0aelfnak","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"privacy,iot","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"TechCrunch","item":"https://daily.dev/sources/tc"},{"@type":"ListItem","position":3,"name":"Comcast adds motion sensing to millions of its newer routers, with a privacy catch"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/comcast-adds-motion-sensing-to-millions-of-its-newer-routers-with-a-privacy-catch-w0aelfnak#faq","mainEntity":[{"@type":"Question","name":"What is Comcast's Wi-Fi Motion feature and which routers support it?","acceptedAnswer":{"@type":"Answer","text":"Wi-Fi Motion is a free, opt-in feature from Comcast that turns Xfinity gateways into motion sensors by detecting interruptions to the Wi-Fi signal, sending notifications through the Xfinity app when activity is detected at home.
