The GPS Plus system represents a state-of-the-art solution for perimeter security, based on innovative differential pressure detection. It accurately monitors any intrusion attempt along the perimeter, promptly identifying climbing, crawling, and crossing actions — both slow and fast. It is also capable of detecting intrusions carried out with vehicles, ensuring complete and discreet protection.
Thanks to its underground and invisible installation, GPS Plus provides a high level of security without affecting the appearance of the surrounding environment.

Installable beneath any surface: sand, grass, gravel, paving blocks, asphalt, etc.

From 10 m to 400/800 m (Stand-Alone and Cloud) / up to 12.8 km (Multiplex). Detection width ranges from 3 to 6 meters depending on configuration

Up to 4 zones (Stand-Alone) / 64 zones (Multiplex)

The GPS Plus system is a truly innovative solution for perimeter protection, completely invisible and undetectable. Its advanced design makes it immune to adverse weather conditions and to small animals, ensuring constant protection. This underground intrusion system can also be installed in hilly terrain as well as in special applications, including indoor environments, offering maximum versatility.
Additionally, it requires minimal maintenance, making it an ideal choice for those seeking an effective and discreet security solution for their property.

GPS® Plus, the Ground Perimeter System, is an underground perimeter protection solution designed for high-risk intrusion sites where discretion and reliability are essential. Based on DSP (Digital Signal Processing) technology, the system digitizes and analyzes the sensor signals in both the time and frequency domains, ensuring extremely accurate processing.
Thanks to these capabilities, GPS® Plus distinguishes recurring disturbances—such as passing trains or vehicles—from actual intrusion attempts, significantly reducing false alarms. Fully passive and undetectable, it offers high immunity to weather conditions and provides continuous, invisible protection that integrates seamlessly into any environment.

GPS® Plus is available in both 2-tube and 4-tube versions, offered in Stand-Alone, Cloud, and Multiplex configurations.
The Stand-Alone and Cloud versions with 2 or 4 tubes and an outdoor DSP analyzer ensure maximum protection for up to 200 meters per system.
The Multiplex version ensures up to 12.8 km of protection with a single perimeter control unit (MIND™). The architecture supports the connection of up to 64 MIND™ units.

GPS® Plus operates by detecting pressure differences between two underground pressurized tubes installed along the perimeter and filled with antifreeze liquid to maintain efficiency even at low temperatures. When an intruder crosses the sensitive zone, the system detects the pressure imbalance and converts it into a signal, which is digitally analyzed to determine alarm conditions with high precision.
The system can store and review signals generated before and after each event, allowing for accurate intrusion analysis. Each section can be calibrated individually to perfectly adapt to site characteristics and optimize sensitivity based on environmental conditions.
The intelligent components of GPS® Plus are supported by a “watchdog” auto-recovery system, ensuring operational continuity even in the presence of anomalies. Fully integrable with other security systems—such as indoor sensors, video surveillance, access control, or fire protection—GPS® Plus is a flexible, reliable, and invisible solution ideal for high-security sites.
