Currently Available

  • More than 3 million units produced annually
  • More than 30 million sensors in the field

Functionality

  • Detects intrusion into the vehicle's interior and triggers alarm
  • Uses a combination of Pulse-Echo (PE) mode and Continuous-Wave (CW) mode
    • PE mode allows low quiescent current consumption
    • CW mode protects against false alarms
