  "account": "Comcast has introduced a new feature called Xfinity Shield that utilizes Wi-Fi routers as home motion detectors, transforming them into a free Wi-Fi sensing system. This technology, known as Wi-Fi Motion, monitors the signal strength and interference between the router and connected devices, detecting unauthorized movement within the home.\n\nOnce detected, the router sends an alert to the user's phone, providing an additional layer of security without requiring any extra hardware. While Wi-Fi Motion may not offer the same level of precision as traditional motion sensors or security cameras, it does not require additional purchases to function.\n\nThis feature is opt-in by default, requiring users to enable it through the Xfinity app and set up alert monitoring. Three protection modes, including Home Watch, Away Watch, and Dark Watch, are available through the app. Wi-Fi Motion is just one aspect of Xfinity Shield, which also includes Xfinity CyberSecure for automatic device protection against phishing and malware, and Family Settings for managing screen time on individual devices.\n\nThe service is available free of charge to Comcast customers with Advanced Xfinity Gateways. For those seeking additional protection, Comcast offers Shield Select for $15/month, which includes an indoor camera, window/door sensors, cloud storage for video footage, and 24/7 emergency response support.",
