Comcast adds motion sensing to millions of its newer routers, with a privacy catch

康卡斯特（Comcast）为其数百万台新款路由器增加了运动感应功能，但伴随隐私隐患

Comcast has rolled out a new motion-sensing technology to its latest home routers, allowing homeowners to receive notifications about activity detected inside their house while they are away. 康卡斯特已为其最新的家用路由器推出了全新的运动感应技术，允许房主在离家时接收有关家中活动检测的通知。

The free feature, called Wi-Fi Motion, turns newer Xfinity gateways into motion sensors by detecting interruptions to the Wi-Fi signal of the wireless network and sends a notification through the Xfinity app. 这项名为“Wi-Fi Motion”的免费功能通过检测无线网络信号的干扰，将较新的 Xfinity 网关转变为运动传感器，并通过 Xfinity 应用程序发送通知。

As first reported by The Verge, the new Wi-Fi Motion feature works for advanced Xfinity gateways XB7 and newer models and is opt-in, which means users can choose whether to switch on the feature in the Xfinity app. As quoted by the publication, customers can use this feature for “motion detection in their home and for a basic level of security.” 据《The Verge》率先报道，这项新的 Wi-Fi Motion 功能适用于高级 Xfinity 网关 XB7 及更新型号，且采用“选择加入”（opt-in）机制，这意味着用户可以自行决定是否在 Xfinity 应用程序中开启该功能。正如该媒体所引述，客户可以使用此功能进行“家庭运动检测，并实现基础的安全防护”。

There is a privacy trade-off. By enabling the feature, Comcast says it may disclose information generated from a customer’s use of Wi-Fi Motion to outside parties under a broad array of reasons — and Comcast says it doesn’t have to tell you. 但这也伴随着隐私权衡。康卡斯特表示，一旦启用该功能，公司可能会出于多种原因向第三方披露客户使用 Wi-Fi Motion 所产生的信息，且康卡斯特声明其无需另行通知用户。

“Comcast may disclose information generated by your Wi-Fi Motion to third parties without further notice to you in connection with any law enforcement investigation or proceeding, any dispute to which Comcast is a party, or pursuant to a court order or subpoena,” reads an Xfinity support page. That’s something to consider before you switch on the feature, particularly if you’re privacy conscious. Xfinity 的支持页面写道：“在涉及任何执法调查或诉讼、康卡斯特作为当事方的任何纠纷，或根据法院命令或传票的情况下，康卡斯特可能会向第三方披露由您的 Wi-Fi Motion 生成的信息，且无需进一步通知您。”在开启此功能之前，您需要慎重考虑这一点，尤其是如果您非常注重隐私的话。
