processStream(); ); OpenCV can read an MJPEG stream using cv2.VideoCapture with the HTTP URL.

Introduction In the world of network surveillance and embedded video systems, few combinations have proven as enduringly useful as Axis CGI and the MJPEG video format. For over two decades, Axis Communications—the market leader in network video—has provided a robust, well-documented Common Gateway Interface (CGI) API. This API allows developers, integrators, and power users to interact directly with the camera’s firmware via simple HTTP requests.

The low latency helps with real-time object detection. 3. Legacy SCADA and Control Rooms Older industrial monitoring systems (no WebRTC support) can display multiple Axis MJPEG streams in an HTML frame grid. 4. Debugging and Field Testing Technicians use /axis-cgi/mjpg/video.cgi to quickly verify camera focus, angle, and lighting without specialized software.
