Didactum Vibration Sensor – Detect Vibrations Reliably

Function

The Didactum Vibration Sensor was specifically developed to reliably detect vibrations, shocks, and mechanical movements that may indicate security-relevant events such as attempted break-ins, glass damage, or structural changes. Due to its high sensitivity, the sensor detects even minor vibrations on surfaces such as walls, doors, windows, or enclosures, enabling precise monitoring of sensitive areas within technical or safety-critical environments.

In combination with a Didactum monitoring system, every detected vibration impulse is captured, evaluated in real-time, and, depending on the configuration, an alarm message is triggered immediately. This can be done automatically via e-mail, SNMP trap, or SMS. This makes it possible to immediately track any unusual movement—a decisive advantage for protecting server rooms, control cabinets, building entrances, or sensitive infrastructure.

The vibration sensor is connected as a plug-and-play sensor to the Didactum monitoring unit via an analog port (A1...A8). After connection, it is automatically recognized and integrated into the measuring system. The sensitivity can be individually adjusted via the monitoring system's software to avoid unnecessary false alarms—for example, due to vibrations from the surroundings. This ensures the sensor provides a balanced ratio of sensitivity and stability.

The Didactum Vibration Sensor is ideally suited for environments where physical manipulations must be detected early. These include, in particular, data centers, telecommunications infrastructures, power distribution systems, ATM rooms, museum depots, and laboratories. In these areas, the slightest impact or blow can already indicate sabotage, unauthorized access, or structural damage.

Furthermore, the sensor system can be flexibly scaled: The sensor expansion unit can significantly increase both the number of connected vibration sensors and the maximum distance to the monitoring unit. This allows even large areas and building complexes to be reliably monitored. In combination with other Didactum sensors—such as those for temperature, humidity, motion, or access—a holistic monitoring concept for physical security and environmental management is created.

With its high sensitivity, easy integration, and robust design, the Didactum Vibration Sensor is an indispensable component of modern security and monitoring solutions. It makes a decisive contribution to early risk detection, avoiding downtime, and ensuring the long-term protection of critical infrastructures.

Use Cases

The vibration sensor can be used for a variety of security and monitoring applications. Thanks to its high sensitivity and precise detection of shocks and vibrations, it offers reliable protection and early detection of potential hazards in diverse environments.

Intrusion Detection: When installed on windows, doors, or walls, the sensor detects vibrations caused by attempted break-ins such as glass breakage or forced entry. This makes the vibration sensor ideal for protecting access points, window fronts, and security-relevant areas.
Building and Structure Monitoring: The sensor can monitor vibrations in buildings or infrastructures to detect structural problems like cracks, loosening, or instabilities early on. This allows for timely maintenance and prevents subsequent damage to structures.
Machine and Equipment Monitoring: The vibration sensor detects unusual oscillations on machines or systems, helping to diagnose mechanical defects, imbalances, or operational malfunctions early - an essential contribution to predictive maintenance in industrial or IT environments.
Vibration-Sensitive Areas: In environments where shocks or vibrations must be controlled - such as laboratories or rooms with sensitive measuring equipment - the sensor supports the maintenance of stable conditions and protects precise equipment from vibration influences.

Thanks to these versatile features, the vibration sensor is optimally suited for both security and industrial applications. It helps to optimize protective measures, detect disturbances early, and ensure continuous operational safety.

Connecting the sensor

Installation:

Option 1.

At the lower end of the sensor's plastic housing, there is a round protrusion. This is used for fastening when the sensor is wall-mounted with a screw. In the current example, it is not needed. If you plan to mount the device differently, skip this step.
Cut off the round protrusion with a knife so that the bottom of the plastic housing is flat.

Option 2.

a) Attach the mounting sensor to the surface using the adhesive sticker.

or

b) Attach the sensor to the surface using a screw.

Option 3.

Attach the sensor to the surface using a mounting bracket.

The mounting bracket and the sensor can be attached either with adhesive stickers or together with screws and nuts.
