mode=motionThis parameter sets the camera’s stream to motion detection mode. When used in a URL, it often bypasses authentication screens to load the motion-triggered viewport directly. In some poorly coded firmware, passing mode=motion or mode=live tells the server, "Stream the video without checking for a login cookie."
Trendnet and other manufacturers patched these viewerframe bypasses years ago. If your camera is running firmware from 2015, it is vulnerable. Check the manufacturer's website today. inurl viewerframe mode motion network camera top
inurl: OperatorThe first part, inurl: , is a Google search operator that instructs the search engine to look for a specific term within the URL (Uniform Resource Locator) of a webpage.

This is far more precise than a general search because it targets the directory structure, file names, and parameters of a website. InURL: viewerframe mode motion network camera top —
