Perimeter detection
Building on the SORHEA legacy, HIRSCH Secure France is the expert in high-security perimeter detection.
Unmatched Reliability: Robust solutions, operational in the harshest conditions.
Maximum accuracy: Our cutting-edge technology minimizes false alerts, ensuring your teams can focus only on real threats.
Active infrared barriers
Infrared barriers rely on active infrared technology, meaning the emission and then reception of a light beam. These barriers are used to create a truly invisible detection wall.
Indeed, IR beams have a wavelength greater than that of visible light (950nm), making any resulting perimeter protection invisible.
Fiber Optics
Distributed Acoustic Sensing (DAS) technology measures acoustic vibrations within an optical fiber using a Rayleigh reflectometer. Acoustic processing of the thousands of captured sounds allows for the detection of distortions in the light passing through the fiber.
optical.
This technology is used for real-time detection, geolocation and classification of activities, thus optimizing the deployment of security agents.
Detector fences and overhangs
Detection fences are a patented, high-security solution. They are perimeter protection devices whose primary function is to physically prevent intrusion.
The panels consist of two plates carrying an electric current, but insulated from each other. Any attempt to cut, shear, or tear them apart brings the two plates into contact, triggering an alarm.
Dual technology detectors
Dual-technology detectors combine a passive infrared (PIR) sensor and a Doppler microwave sensor. Both sensors must detect an intrusion to trigger an alarm.
The passive infrared detector detects temperature variations in its detection field and the Doppler sensor emits a pulse and analyzes the signal reflected by the environment.
Thermal detectors for video analysis
Video analysis is a software technology that involves analyzing video images from thermal detectors.
The goal is to capture all activity within the monitored area, regardless of environmental conditions, and then analyze these images to optimize detection. An alarm notification is transmitted according to the chosen settings.
Buried microwave cables
Buried cable technology is a detection system consisting of two microwave coaxial cables buried underground and therefore invisible.
The two microwave coaxial cables of this technology then form a detection lobe which measures approximately 2m wide by 1.25m high which detects any attempt at intrusion along the protected perimeter.
Microwave barriers
Microwave detectors consist of a transmitter that generates a directional electromagnetic field, and a receiver that detects and analyzes the change in this field when the monitored area is crossed.
Microwave technology is based on the emission and then the analysis of a very high frequency radio wave.
Integration
We have developed Maxibus Universal, a hub that centralizes alarm information from all our products as well as third-party products.
It allows connection to the various alarm operating systems (VMS, GTC, alarm control panels, hypervisor).
All our products are networked on this hub, either natively or via REMOTE 8-INPUT MODULE (MI8), our radio or wired communication module.
Maxibus Universal interfaces with alarm operating systems: via relay output (dry contacts), via ModBus protocol (RTU or TCP) or via Smart Device software, our VMS gateway (Genetec, Seetec, Milestone).
