Free shipping within the Czech Republic.
Milesight VS373 is an intelligent sensor designed for continuous indoor human monitoring. Thanks to advanced 4D 60 GHz mmWave radar technology and AI algorithms, it can detect falls with up to 99% accuracy without physical contact. The sensor also recognizes unusual immobility, bed presence, and room occupancy. It provides 24/7 continuous monitoring, with an alert system using LED indicators, a buzzer, and backend notifications.
The device ensures 100% privacy protection as it does not capture images or audio. It supports the Milesight D2D protocol for direct communication with other devices without requiring a LoRaWAN gateway, enabling quick response to detected events.
Installation is simple thanks to the ceiling mounting and USB-C power supply. The sensor is dust and water-resistant (IP65), ensuring reliable operation even in demanding environments.
Before you install
- Setup: in a browser after connecting to the sensor's Wi-Fi, no app needed.
- Power: a USB-C adapter is included; for ceiling mounting keep a socket within cable reach (or use an extension / PoE splitter).
- Alerts: a local alarm (buzzer / LED / output), or via a LoRaWAN gateway for remote monitoring through the Milesight platform (free for up to 10 devices; gateway sold separately).
