Why Node-RED

The OV20i includes the easiest to use deep learning engine on the market for manufacturing inspection. But how do you connect the useful outputs to the rest of your factory?

Overview has included Node RED in the OV20i to extend our powerful, but easy to use functionality to the product’s integration interface.

Ease of Integration: Node-RED provides a wide range of built-in nodes and supports a vast number of external integrations, protocols, and devices. This means that users can easily connect their OV20i to various sensors, actuators, databases, cloud services, and APIs without extensive coding. With each image processed, users can send data to adjacent robots, ongoing SCADA systems, and historic databases. 

Open Source and Community Support: Node-RED is 
an open-source project with an active community. This means users have access to a wealth of resources, tutorials, and contributed nodes. This can reduces development time and help troubleshoot issues effectively. We find the the subreddit ( useful and the official website (

Scalability: Node-RED is highly scalable, making it suitable for both small-scale and large-scale industrial applications. Designers can start with a simple workflow and then expand it to accommodate more complex processes as their use case evolves.

Flexibility: The flexibility of Node-RED allows users to create custom logic and workflows tailored to their specific process requirements. This adaptability is crucial when dealing with unique manufacturing environments or corporate standards.

Rapid Prototyping and Development: Node-RED offers a visual and intuitive interface that allows users to quickly prototype and develop applications

Customization: Node RED allows custom nodes. Data can be passed back and forth over EthernetIP/Profinet to a PLC through the OV20i’s custom nodes.

The Node RED I/O portion of the OV20i can significantly streamline development, reduce integration time, while increasing integration points, improve scalability, and provide unlimited flexibility. It’s a powerful tool for manufacturing engineers trying to automate more and more of their inspections.
