Installation and performance: Ceiling mounting at 2.3–3 m; coverage 2 × 2 m to 4 × 5 m depending on mounting height. The stated 99% fall capture rate is a laboratory result for a single-person scene with correct installation and without strongly reflective or moving objects. This is an auxiliary tool and does not replace manual monitoring or personal companionship.
The Milesight VS373 is an advanced radar-based fall detection sensor, designed to provide real-time monitoring and safety for elderly care, healthcare environments, and smart buildings.

Using 60GHz millimeter-wave radar with AI algorithms, the VS373 detects human falls with up to 99% accuracy, without requiring wearable devices or cameras. It ensures 100% privacy protection while delivering highly reliable monitoring even in dark or humid environments.
The sensor supports LoRaWAN® connectivity, enabling long-range wireless communication and seamless integration with IoT platforms. It also supports Milesight D2D communication for ultra-low latency local automation.
