If you want, I can:

In web development, "mode" often refers to a state or configuration. In these old surveillance systems, mode could dictate whether the user was viewing live (motion), playback, or setup. The inclusion of mode in the URL suggests the page is expecting a specific instruction.

In the early 2000s, IP cameras (network cameras) were a novelty. Manufacturers focused on features (remote viewing, pan/tilt/zoom) rather than security. Consequently, many devices shipped with (username: admin / password: password or blank). Worse, some models were configured to allow unauthenticated access to the viewerframe page.

This phrase reads like a compound search query and touches on web-URL operators, embedded viewers/modes, motion/video contexts, hospitality (hotel), and verification flags. Below I unpack likely meanings, risks, uses, and practical steps for investigation and responsible handling.
