Remote monitoring and control

Establish Functional Safety with Qt

Functional safety is increasingly crucial across diverse industrial environments, hospitals, roads, railways, construction zones, and manufactures. Using Qt, built on C++, we can create advanced software and embedded systems providing robust security features vital for protecting sensitive industrial data.

Our approach incorporates Qt Safe Renderer, a tool designed for meeting certification standards and presenting key information on manufacturing processes, equipment status, and safety alarms.

Qt safe renderer

Qt Safe Renderer achieves this by segregating safety-critical functionality into an independent subsystem with its dedicated process. This ensures continuous operation of the safety-critical component, even in the event of a main UI failure.

Furthermore, the Qt code adheres to essential standards such as IEC61508, IEC62304, or ISO26262, underscoring our commitment to meeting safety requirements.

What We Do


leverages the full capabilities of Qt framework, containing the display logic for the interface


serves as the core for business logic, encompassing services, code, and libraries controlling custom hardware or specific algorithms. In industrial applications, this level often comprises multiple distinct applications rather than a monolithic executable

Qt runtime libraries

encompass core internals, support functions, and Qt libraries, covering UI components (Qt Widgets, Qt Quick/QML, Qt 3D, printing) and non-UI functionality (containers, strings, IPC, threading, parsers)

C++ runtime libraries

include runtime components and libraries from the C++ compiler, such as STL or Boost

Third-party components

encompass external software libraries, databases, or protocol stacks that extend beyond the core Qt system

Operating system

serves as the interface to hardware, ranging from desktop OS, Linux variants, to Real-Time Operating Systems (RTOS), depending on your requirements


Leveraging Qt for Device Creation, we develop IIoT devices and robotics hardware for our clients. Whether connected wirelessly or not, these devices offer seamless interaction through various interfaces, such as physical knobs and touchscreens.

Qt for Device Creation streamlines our embedded system development, ensuring swift boot times with Boot to Qt technology and incorporating valuable components tailored for industrial solutions.

HMI systems

We develop Human Machine Interface (HMI) systems, leveraging our expertise in creating software with advanced user interfaces for touchscreen devices.

With Qt Quick technology, we incorporate modern features like touchscreens, gestures, haptic controls, and focus-directing animations, enhancing user interaction and delivering interfaces akin to smartphones.

SCADA Systems

Our team ensures seamless real-time control over decentralised processes, incorporating features like multi-thread execution, on-demand behaviour, and optimised memory management.

Qt's architecture, designed for performance, facilitates the development of SCADA systems capable of handling extensive data from remote sensors and rendering sophisticated 2D and 3D graphics.

Digital Twins

To create accurate 3D digital replicas of physical systems, we build Qt-based solutions that visualise your data and processes, control the equipment status, detect dangerous patterns, and identify optimisation strategies.

Our team delivers cutting-edge solutions that enhance predictive analytics, system monitoring, and overall operational insights.
