UWB-Radar 7.9 is our brand new product as the whole product type in miniaturized size and competitive price. It is specialized for presence (occupancy) detection in a specific area. It  judges an occupancy status accurately even in a breathing-only, no-movement condition, without invading privacy at all.
  • Easy to use (apply to ceiling)
  • Whole product type - including product case
  • Contactless radar technology prevents your privacy
  • Judges an occupancy status accurately even in a breathing-only, no-movement codition
  • Wired/wireless data communication - UART(Default), Relay, RS485
  • presence, activity, intrusion detection without cameras
  • Integrated algorithm firmware is available upon request


  • Algorithm firmware can be customized to your application depending on your order quantity
  • Additional algorithm firmware will be available in order
