Instead of displaying video immediately, the page shows a list of camera names (e.g., "Camera 01 - Front Entrance," "Camera 02 - Server Room"). Clicking on these names loads a live feed via a helper application like Java, ActiveX, or a simple JPEG refresh stream.
Security researchers and "Google hackers" use these strings to identify IoT (Internet of Things) devices that have been connected to the internet without proper password protection. When a camera is indexed by Google with its default settings, anyone can potentially view the live feed simply by clicking the search result.
