Shelly’s new presence sensor simultaneously detects up to 10 people without a camera

Shelly has released a new presence sensor, called the Presence Gen4, which uses mmWave radar technology to detect up to 10 people within a room or space without the need for a camera. The sensor is designed for smart home automation and is a companion product to the company's recently launched $50 subscription-free security camera. The Presence Gen4 sensor can track individuals as they move through a space, providing data on occupancy and movement patterns.
