Secure What Matters Most

Security systems are indispensable to any type of building and guarded asset. Commercial properties, airports, retail shops, industrial enterprises, financial and governmental institutions, schools, medical facilities, oil and gas companies as well as residential complexes require a unique set of safety and security measures because each type of property is vulnerable to different hazards.

High security businesses that require state-of-the-art security monitoring for highly sensitive areas, trust HSI Sensing’s Sentinel technology–which can monitor precise location and strength of all magnetic fields within proximity of the sensor, delivering a 360-degree scope to monitor activity from every angle. And, Sentinel is discrete. Sentinel can accomplish all the actions required of a high security sensor in a package that is less than half the size of comparable sensors.

High Security Applications

  • Shipping Container Door Security
  • Commercial Alarm Systems
  • Discrete Location Sensors
  • Residential Alarm Systems
  • Government High Security Systems
  • Cargo Container Sensors
  • SCIFs (Sensitive Compartmented Information Facility)
