At its core, the viewerframe component refers to the structural environment where a live video feed is rendered within a web browser or monitoring application. Most modern IP cameras utilize a web-based GUI (Graphic User Interface) to display footage. The viewerframe acts as the container for the video stream, dictating how the browser handles incoming packets of visual data.
