Ring Video Doorbell 3(如图)售价200美元。
环环周三，亚马逊(Amazon)的智能家居安全品牌亚马逊(Amazon)又增加了两款电池供电的手机门铃包括200美元的视频门铃3和230美元的视频门铃3 Plus。虽然它们看起来与Ring之前的产品相似，但该公司表示，这两款产品都“改进了运动检测”。
视频门铃3 Plus有一个特别的功能叫做预滚。Pre-Roll记录了4秒的活动之前摄像机检测运动。理论上，这应该比其他的Ring蜂鸣器能捕捉到更多的事件，但我们必须亲自测试它来比较两者的区别。
Ring最近成了头条新闻它与当地警察部门的合作关系在美国各地引发了隐私倡导者关于哪些信息与执法部门共享，以及如何使用这些数据．去年12月,Ring的数据泄露了这暴露了用户的个人信息。
