Schmeissner: Capacitive breakthrough protection (GSA27-D55)
Capacitive Break‑Through Detection for Wall and Surface Monitoring

The manufacturer Schmeissner introduces a capacitive break‑through detection system certified to VdS Class C. According to the manufacturer, the solution provides wide‑area monitoring of walls and ceiling structures to detect drilling, break‑ins and concealed manipulation – areas that often remain insufficiently protected in high‑security facilities.
Technology and Functionality
The system is based on a multilayer sensor structure using conductive fleece. Three sensor layers create a defined capacitive measurement field. Two insulating layers and an electromagnetically shielded structure provide, according to the manufacturer, resistance to interference and manipulation. The finished surface can be painted and blends unobtrusively into the environment.
Monitoring of Large Areas
With the Cx 1 capacitive field‑change detector, a single sensor covers up to 50 m². The electronics automatically adapt to environmental conditions, which simplifies commissioning according to manufacturer data.
Installation and Integration
The system suits both new construction and retrofit projects. Adhesive‑based installation supports fast mounting on various surfaces. Standardized components help enable predictable planning.
Certification
The solution is certified to VdS Class C, the highest security level for intrusion detection technology. According to the manufacturer, the certification confirms manipulation protection, interference resistance and reliable detection performance.
Typical Application Areas
- Banks and cash handling areas
- Data centers
- Government facilities with classified zones
- Military sites
- Correctional facilities
- Jewelry stores and high‑value retail
- Buildings with elevated threat levels
Conclusion
The capacitive break‑through detection system adds area‑wide monitoring of wall and ceiling structures to conventional intrusion detection solutions. According to the manufacturer, it provides a norm‑compliant way to protect sensitive areas and integrate seamlessly into modern security concepts.
