High-Sensitivity Motion & Presence Detectors
Presence and Motion Detection Solutions Developed by Theben
Theben develops presence and motion detection solutions designed to support automatic control of lighting and building functions. As a manufacturer of detection devices, Theben focuses on products that respond reliably to occupancy and movement, helping systems operate in line with real-world use.
These detection solutions form part of Theben’s wider expertise in control technology, supporting structured system behaviour and dependable operation across different environments.
Smart Motion & Presence Control
Presence and motion detection plays an important role in creating buildings that are efficient, safe, and easy to manage. At Theben, our experienced team works with homeowners, facilities managers, and commercial operators to deliver detection solutions that respond accurately to real movement and occupancy. Presence and motion detection supports automatic control of lighting and, where required, other building systems so they operate only when needed. This approach improves comfort, reduces wasted energy, and ensures reliable performance across a wide range of environments throughout the UK.
How Presence and Motion Detection Improve Smart Buildings
Presence and motion detection systems refers to sensor-based systems that identify whether people are moving through or occupying a space. Motion detection is designed to pick up larger movements such as walking, making it suitable for corridors and circulation areas. Presence detection is more sensitive and can detect small movements like typing or shifting position, which is ideal for offices and meeting rooms.
These systems are commonly used to automate lighting and can also support heating or ventilation control. Presence and motion detection systems helps ensure building systems respond to real usage rather than fixed schedules. This results in more efficient operation and a better experience for occupants in residential, commercial, and public buildings.
Energy-Efficient Lighting Control with Presence Detectors
Theben’s presence detectors are the ultimate solution for intelligent, energy-saving lighting control. Perfect for offices, corridors, and public buildings, our detectors also enable heating and air conditioning to be managed based on occupancy. This not only helps reduce energy costs but also significantly cuts CO2 emissions.
Our presence detectors respond to even the slightest movement and continuously monitor ambient light levels. When no movement is detected or the set brightness threshold is exceeded, the detector automatically switches off the lighting, ensuring no energy is wasted.

How Presence and Motion Detection Works
Presence and motion detection systems identify movement or occupancy within a space and trigger predefined control actions. When activity is detected, connected systems such as lighting can respond automatically, providing light or function only when required.
Detection behaviour can be adapted to suit different areas and usage patterns, allowing control systems to respond appropriately to how spaces are used throughout the day.
What’s the Difference Between a Motion Sensor and a Presence Detector?
The key distinction lies in sensitivity:
- Presence detectors feature highly sensitive sensors that divide their detection area into up to 1000 zones, enabling them to pick up even the smallest movements – like someone typing at a desk. They also offer continuous light measurement, turning lights off as soon as sufficient daylight is available, even if movement continues. This maximises energy savings and reduces CO2 emissions.
- Motion sensors (PIR sensors) are ideal for detecting larger, more obvious movements, such as someone walking through a hallway or approaching a building entrance. However, they typically measure light only once – when first activated – meaning lights can remain on unnecessarily if movement is ongoing.
Why Presence and Motion Detection Systems Matter
Presence and motion detection helps lower energy consumption by switching lights and connected systems on only when spaces are occupied. Empty rooms are no longer lit unnecessarily, reducing wasted electricity. Automatic control works consistently throughout the day without user input. Over time, this leads to measurable energy savings and more efficient building operation.
Lighting controlled by presence and motion detection systems responds immediately when someone enters a room. Presence detectors maintain operation even during periods of low movement, ensuring lights stay on while a space is in use. This removes the frustration of lights switching off unexpectedly. Occupants experience a more comfortable and reliable environment.
Automatically activated lighting improves visibility in stairwells, corridors, and entrances. Presence and motion detection systems ensures these areas are illuminated when movement is detected, reducing the risk of trips or accidents. This is especially important in shared or public spaces. Better lighting control supports a safer overall environment.
Presence and motion detection systems can be applied across many settings, from private homes to large commercial buildings. Sensors can be adjusted for detection range, sensitivity, and time delays. This flexibility allows solutions to match how each space is used. Both simple installations and complex layouts benefit from adaptable detection control.
Modern presence detectors and motion sensors are designed for long-term reliability. Robust construction and proven detection technology ensure consistent performance over time. This reduces maintenance needs and system downtime. Reliable detection helps building systems operate as intended day after day.
Square Detection Area for Precise Coverage
Our presence detectors feature a square detection area with a 360° field of view, making planning simple and effective – especially for square or rectangular rooms. This ensures seamless coverage without blind spots or overlaps, offering reliable detection throughout the entire space. Unlike circular detection zones, our square layout provides optimal room coverage with maximum precision.
