Invisible Protection

SISMA CA

Subflooring intrusion detection system

SISMA CA is an intrusion detection system for outdoor floors with concrete base. Patented by DEA Security, it employs special pressure sensors that detect the movement or presence of a person on the protected area. Being embedded in the concrete screed, the sensors are invisible and virtually tamper-proof.

What it is

SISMA CA is a subflooring intrusion detection system for outdoor floors with concrete base. Patented by DEA Security, it employs special pressure sensors that detect the movement or presence of a person on the protected area. Since they are embedded in the concrete screed, the sensors are invisible and virtually tamper-proof.

Where it is used

SISMA CA discreetly protects all paved areas in front of the access points of a building, such as doors, windows and glass surfaces, signaling the intrusion even before the intruder penetrates inside the protected building. It can also be used to sensorize terraces, driveways and walkways.

Key Features

Advanced geoseismic technology

Invisible protection

Embedded in the concrete screed of the flooring, the system is completely invisible from the outside, preserving the aesthetics of the environment.

Weather immunity

Totally immune to weather conditions, it works perfectly with rain, snow, hail and extreme temperatures.

Pet-friendly

Immune to pets thanks to minimum weight calibration, avoiding false alarms from dogs and cats.

No maintenance required

The sensor requires no maintenance once installed, ensuring long-term reliability without periodic interventions.

High sensitivity

Detects even discrete movements such as soft footsteps, crawling or creeping movements.

Non-deformable

Resistant to mechanical stress, it maintains performance even under heavy loads and accidental impacts.

Module-based calibration

Each module can be calibrated and configured independently from the others, with the possibility of varying the security level according to the risk level relative to that area.

No blind spots

Environmental factors that reduce visibility, such as obstacles, uneven surfaces and fog, are completely irrelevant here.

Double knock

The processing unit features double knock (AND detection) to effectively discriminate any environmental disturbances from actual intrusions.

How it works

Pressure sensor detection

SISMA CA sensors detect pressure changes (weight) between the screed in which they are embedded and the overlying flooring. When a person walks over the protected area, the weight exerted is detected and generates an alarm.

Each SISMA CA module provides independent alarm signals, allowing very precise identification of the area under intrusion and individual calibration of each zone. The most important feature consists in its invisibility: it does not interfere in any way with the aesthetics and architectural elements of the place where it is installed.
