Product Overview
SensorX: Audiovisual Signal Detector for Vehicle Interiors with Embedded Web Interface
SensorX is a high‑performance measurement system designed for the reliable detection and recording of audio‑visual driver warning signals in vehicle interiors. The system enables precise, time‑synchronous capture of visual and acoustic signals as they are presented to the driver.
Equipped with high‑resolution cameras, SensorX detects changes in icon shape, color, and status within the instrument cluster. A high‑precision microphone identifies defined acoustic warning patterns and sound events. Both visual and acoustic signals are detected within a few milliseconds.
Upon detection, SensorX outputs the measurement results in real time via digital trigger signals as well as LAN and/or CAN messages, allowing seamless integration into automotive test environments, ADAS validation setups, and automated measurement workflows.

Performance & configuration
High-Performance Camera
With the help of industrial camera systems, SensorX detects changes in shape and color and processes them in real time. This makes it possible to process several signals in parallel and output the results as digital trigger signals and UDP and CAN messages with low latency.
Technical Data
The SensorX camera systems are housed in robust IP67 enclosures for reliable use in demanding vehicle environments. Integrated, multifunctional mounting options enable flexible installation in various test setups. Multiple threaded mounting points and a standard ¼‑inch camera mount allow secure attachment, including direct installation on the dashboard.
Microphone
The highly sensitive microphone of the SensorX is able to check and recognize sound patterns as well as single and multi-frequency sounds in real time.
Technical Data
Core functions & extensions
In the basic configuration, the SensorX system is equipped with a camera and a microphone. With the associated basic software license, 1 symbol with up to 3 associated statuses and 2 acoustic signals can be monitored.
Symbol recognition
SensorX has the ability to learn user-defined symbols and reliably detect them in image data. The symbols can be trained using both synthetically generated images and live images from a connected camera. For recognition, the learned symbol is localized within a defined search area in the camera image. Integrated pre-processing compensates for camera-related movements such as vibrations or slight positional deviations. For this purpose, the search area is dynamically adapted to the detected image shifts to ensure robust and stable detection.
Status detection
Different states can be defined for each recognized symbol. A state results from several distinguishable areas within the symbol, each of which is assigned a specific color. These color assignments serve as the basis for evaluating and classifying the current status. The definition areas can be configured manually or generated automatically. The corresponding color values can either be predefined or determined on the basis of live images. A condition is considered detected as soon as all defined areas have the assigned colour characteristics.
Sound recognition
SensorX has the ability to learn user-defined symbols and reliably detect them in image data. The symbols can be trained using both synthetically generated images and live images from a connected camera. For recognition, the learned symbol is localized within a defined search area in the camera image.
