• DISCRETION: Invisible and totally undetectable protection
  • OPTIMISED OPERATION: 1 single trench (15cm wide), identical Rx and Tx cables (easy maintenance)
  • RELIABILITY: Adjustable sensitivity. Calibration of the detection threshold according to soil type




Product Details


TALPA is an intrusion sensor generating an invisible detection field consisting of a pair of underground cables (Tx and Rx) capable of accurately detecting and locating (within 1m, information available at the TALPA management unit) any attempt to intrude.

TALPA is one of the most efficient detection systems on the market, since it is invisible and undetectable. It thus guarantees the security of the site, while maintaining its aesthetic and optimizing its installation.

In operation, TALPA creates a microwave detection lobe whose signal variations are analyzed by a
management unit. Any person crossing this lobe will disturb the signal and an alarm will be triggered if the detection threshold is exceeded.

Powered by 12Vdc or 48Vdc, each management unit can manage up to 800m of TALPA cables distributed
over 2 departures. It is possible to connect several TALPA management units on the same site to cover
perimeters greater than 800m.

During an intrusion, the alarm information is relayed by dry contacts directly via the TALPA management unit (microprocessor).


The technology and the advantages of the TALPA system enable it to be installed on all sensitive

sites requiring a high level of security and discretion: prisons and prisons, monuments and historical heritage sites, villas and residences.

Detector cables are intelligent buried detection systems. They are composed of two microwave coaxial cables buried underground in the same trench and therefore invisible.

The buried cable technology is a detection system consisting of two microwave coaxial cables buried underground and therefore invisible. The two coaxial cables create a radio frequency detection field.

These cables are connected to electronic management units.

The cables (one transmitter and the other receiver) are installed in a single trench along the perimeter to be protected. They then create a detection lobe whose values of radio frequency signals are analysed continuously.

During an intrusion, the signal variations caused by the cutoff of the detection lobe are processed by the
management units, and an alarm is triggered.
