Intrusion Detection
Intrusion detection systems that detect reliably and minimize false alarms — compliant with DIN EN 50131 and VdS.
Overview
An intrusion detection system must reliably do two things: detect genuine events and avoid false alarms. Both depend on sound planning — an over-sensitive system loses trust through constant false alarms, an under-sensitive one fails to detect the real event. We design intrusion detection per the DIN EN 50131 series and the VdS guidelines.
It begins with determining the required grade of the system. DIN EN 50131 distinguishes four security grades depending on the expected attacker profile and protection needs — from simple protection to safeguarding against planned, skilled attacks. The grade dictates requirements for detectors, control panel, transmission and power supply. This way the system matches the actual risk, neither over- nor under-dimensioned.
The real craft lies in detection planning. Detector groups, monitoring types (shell, trap or focal-point monitoring), arming concepts and the avoidance of interference sources determine the false-alarm rate and effectiveness. We plan the entire signaling chain up to connection to an alarm receiving and service centre, so that every signal reliably leads to an appropriate response.
Where insurers or authorities require evidence, the VdS guidelines are decisive. VdS-approved systems are often a precondition for insurance cover at higher values. We ensure a documented, standard-compliant implementation and the necessary evidence — so the system not only works in the event of damage but is also recognized for insurance purposes.
Intrusion detection is most powerful in combination. We integrate it with video verification, access control and perimeter protection and connect it to a security control room — turning a mere signal into a swift, targeted intervention.

Frequently asked questions
Which standard applies to intrusion detection systems?
The DIN EN 50131 series describes requirements for devices and systems and distinguishes four security grades. The VdS guidelines, often required by insurers, apply in addition.
How can false alarms be reduced?
Through proper planning of detector groups, monitoring types, arming concepts and the technology used — as well as video verification. This is precisely what the relevant standards address, and precisely where we place the planning focus.
Do I need a VdS-approved system?
Often yes — particularly when the insurer requires evidence or higher values are insured. VdS approval is frequently a precondition for cover. We clarify the required standard before planning and implement it demonstrably.
