Alarm system

概要

Build better protection for homes and businesses with the most advance security solution with Infineon’s sensor fusion based alarm system powered by XENSIV™ sensors

The Infineon’s alarm system is a multi-layered security system that uses data from XENSIV™ IM69D130 microphone and XENSIV™ DPS310 barometric pressure sensor to provide true protection against burglary and intruder events. Both hardware components operate on separate algorithms and thread it into one with a sophisticated sensor fusion algorithm. With our patent-pending concept of combining audio with pressure information, Infineon’s alarm system only acts when you expect it to. Both Sensors have to be triggered at the same time for an alarm. The System is more robust and cannot be triggered by various sounds like a dog barking or background noise from a movie, avoiding false alarms.

Infineon’s alarm system enables the detection of two event types:

  • Glassbreak – when a window or door glass is broken, the algorithm extracts the intensities in the frequency spectrum. At the same time, it captures the signature pattern of the change in pressure inside the room. The sensor fusion software synchronizes the outputs and triggers a glass break alarm.
  • Intruder – when all windows and doors are closed, there is a stable pressure inside the room. Opening or closing a window or door triggers a pressure change within the room. Each pressure event has a signature pattern. Therefore, opening or closing a door or window triggers an intruder alarm.

The Infineon’s alarm system, based on XENSIV™ IM69D130 microphone and DPS310 barometric pressure sensor, brings the following features and benefits to your application:

Features of Infineon Alarm System Solution Benefits for your application and its design

1. Glass break detection - Sensor fusion software and algorithm recognize the two sensors signature data pattern

  • Microphones detect acoustic events, e.g. sounds of window/door glass break
  • The pressure sensor detects pressure change events, e.g. change in pressure in the room when the window/door glass is smashed

2. Intruder Detection – A machine learning-based algorithm to detect the opening/closing of door/ window

  • The pressure sensor detects the change in events e.g. signature change in pressure when the window/door is opened/closed
  • Holistic perimeter protection with high reliability

The unique glass break and intrusion detection concept provides robust protection with reduced false alarms
  • Glass break detection system in high sensitivity settings – 99%**
  • Intruder detection – 96%**
**tested according to Infineon test methods

Reliable coverage of up to 50m2 room with one alarm system without a line of sight requirement

 Flexible design and placement with adjustable sensitivity for different house environments

Infineon’s patent-pending sensor fusion concept enables higher accuracy and precision for intrusion detection
