SIEZA PERIDECT+ UNDERGROUND - The "Unhide" Perimeter Protection

PERIDECT + Underground protects objects or areas from intrusion by unauthorized persons. Buried detectors bring an invisible and reliable defence. Peridect+ Underground combines the benefits of Peridect and Peridect+ systems. It can be installed purely as an underground detection system, or it can combine underground and fence detection. Thanks to trusted technology behind Peridect and Peridect+, our underground solution provides high detection accuracy and extremely low false alarm rate. Peridect+ Underground protects the perimeter of power plants, prisons, civil and military airports, factories, but also villas and other applications with high-security demand.


  • EXTREMELY LOW NUISANCE ALARM RATE Thanks to piezoelectric sensors and unique evaluation algorithms Peridect+ Underground dramatically reduces nuisance alarms caused by weather conditions.

  • PERIMETER LENGTH Length of protected area can be hundreds of kilometers if you cascade CUP+ control units. One LCP+ control unit covers up to 1 km of your perimeter.

  • DETECTION ACCURACY Thanks to addressable sensors Peridect+ Underground supports very high detection accuracy – typically 2m.

  • MODULARITY Modular architecture of Peridect+ Underground allows easy modification and system extension in the future.

  • BURRIED AND FENCE SENSORS AT ONE DETECTION LINE Peridect+ can be installed on all common types of fencing but also on non-standard fencing like metal plates and welded decorative fences. A combination of fence and buried detectors at one detection line supported.

  • NATIVE INTEGRATION WITH IP CAMERAS In case of intrusion detection, the external IP PTZ camera is automatically directed to move to the intrusion area for two-step verification.
