继上月推出50美元免订阅安防摄像头之后，Shelly今日宣布推出另一款智能家居自动化新配件，可在人员在房间或大型空间中移动时追踪多个人员，且不对其进行录制。Shelly Presence Gen4传感器采用毫米波雷达技术而非摄像头，以检测人员和宠物的存在、运动和活动。该产品今日起通过Shelly官方在线商店发售，售价84.99美元，预计将很快在亚马逊和百思买等其他零售渠道上架。
Following the launch of its $50 subscription-free security camera last month, Shelly announced another new accessory for smart home automation today that can keep track of multiple people as they move through rooms or large spaces without recording them. The Shelly Presence Gen4 sensor uses mmWave radar technology instead of a camera to detect the presence, motions, and activities of people and pets. It's available starting today for $84.99 through Shelly's online store and is expected to hit other retailers like Amazon and Best Buy soon.
