UWB prevent disassembly watch

R9 is a professional watch with high-precision heart rate monitoring and positioning. The device integrates motion and heart rate sensors, which can continuously monitor heart rate changes and automatically identify activity status. The built-in ble5.0 module is compatible with a variety of Bluetooth protocols and IP68 waterproof design, so that the device can be used normally in various harsh environments. The watch strap has the function of anti disassembly alarm. The whole machine does not use any metal shell. It is safe and reliable to wear. It also has the important characteristics of low power consumption and low power electromagnetic radiation. It is especially suitable for prison, detention center, drug treatment center and other scenes to monitor the position and heart rate of indoor personnel. It can communicate with UWB and nb-iot.
