Coding Custom Thermal Imaging Applications with the Optris SDK

What is the OTC SDK – and Why Do You Need It?

The OTC SDK, the Optris Thermal Camera Software Development Kit, is a library of functions that enable software developers to create custom software applications for Optris Thermal Imaging Cameras. It is a digital toolbox that includes everything needed to connect and work with Optris thermal cameras, such as sample programs in different software languages, useful code libraries, searchable documentation, an FAQ, and clear instructions on where to start.

With the SDK, companies build their custom solutions to post-process temperature data from Optris thermal cameras. The API allows full control over how the thermal camera is utilized and how the thermal data is processed, making it ideal for in-depth integration in manufacturing, research, or machine builders. The SDK is a tool to empower Developers and Engineers to build fast, flexible and easy Integrations with Optris Products.

The Optris OTC SDK enables customers to create custom applications for thermal imaging and infrared temperature monitoring. Whether integrating a single camera or developing complex systems with multiple infrared imaging devices, the SDK provides comprehensive access to all camera features. All features accessible are the same as in the PIX Connect software.

The application interface includes libraries, example code, and detailed documentation for Windows and Linux and for and different processing platforms. The SDK is completely free! There are no costs or hidden fees for users. Designed for developers of all levels, it simplifies integration and accelerates tailored in depth integration of the thermal cameras into other systems across industries.

A Complete Toolkit for Custom Integration

The Optris SDK, is a future-proof, flexible development platform for integrating Optris infrared cameras into customer-specific software solutions. The SDK includes precompiled examples, libraries, configuration tools, and extensive documentation.

It supports C++, C#, and Python and is available for both Windows and Linux. Whether the application is industrial, scientific, or research-oriented, the SDK provides direct access to thermal data and camera control parameters – from emissivity settings to frame rates and video formats.

Wide Camera Compatibility

The Optris SDK supports all current Optris infrared cameras, including the Xi and PI series. Multiple thermal cameras can be managed in a single application, whether connected via USB or Ethernet, allowing versatile multi-camera setups.
Additionally, the SDK can handle mixed setups – for example, combining USB and Ethernet devices or integrating remote units via a network. It includes functionality for automatic device detection (USB) and manual IP-based configuration (Ethernet).

Free Licensing, Open Use

The Optris OTC SDK is completely free of charge when you purchase an Optris camera. There are no license fees, no subscriptions, and no restrictions on commercial use. The SDK is maintained by both Optris and the partnering company EduArt, ensuring ongoing updates, support, and compatibility with future camera models and software tools.

Unified Development for All Applications

Whether an engineer working on production line monitoring, a researcher analyzing temperature patterns, or a developer integrating thermal vision into a control system, all users benefit from the same toolkit, ensuring consistent functionality across the board.

From sample code and quick-start guides to support for automated setup and live streaming, the OTC SDK is designed to be intuitive and developer-friendly.

Remote Camera Control & Parameter Configuration

All key thermal camera parameters—such as emissivity, measurement range, focus, or color palette—can be configured directly via the OTC SDK. This is particularly useful for thermal cameras installed in hard-to-reach or hazardous areas, such as inside furnaces or robotic cells. Parameters can be changed dynamically during operation and adjusted to changing process conditions.

Advanced Image Processing & Analysis and Custom Visualization With GUI Elements

The OTC SDK provides access to raw thermal image data, enabling developers to apply create custom filters, segmentation algorithms or machine learning models. Applications include defect detection, thermal pattern recognition, and automated quality control.
Additionally, developers can create customized user interfaces tailored. Such interface could display measurement zones, limit indicators, status symbols or interactive features. The result is tailored custom-made to the demands of operators, engineers, or inspection staff.

Further development and future features

Future OTC SDK updates will include export functions for saving temperature data as CSV- and thermal images as PNG-files. This enables long-term documentation, traceability, and external analysis. Export can be triggered manually or integrated into automated data logging systems.

Due to numerous user suggestions requesting the ability to create their own solutions independently of the complete Optris PIX Connect software, it is also planned to expand well-known functionalities of the PIX Connect into the OTC SDK, thereby completing the further development of the previous ConnectSDK at a later date.
