If you're looking to understand or access a hotel's surveillance feed or a similar viewer frame for legitimate purposes (such as ensuring safety and security), here are some points to consider:

You may wonder why "hotel" is specifically targeted. Hotels represent a perfect storm of security vulnerabilities for three reasons:

When combined, a hotel with an outdated AVTECH DVR, port-forwarded to the internet, becomes indexable by Google. A query using inurl:viewerframe effectively becomes a Google dork—a search that reveals sensitive information not intended for public access.

In URL parameters, "mode" typically defines the operational state of the viewer. In AVTECH DVRs, mode values could include:

The presence of "mode" suggests the search is trying to capture specific streaming states.

If you run a hotel, motel, or any short-term rental with security cameras, this should be a wake-up call.

Google Dorking is the practice of using advanced search operators to find information that isn’t meant to be public. The operator inurl: tells Google to look for specific text inside the URL of a webpage.

When you combine them, you are asking Google: “Show me every webpage on the internet that has a live motion camera viewer in its URL.”

In the early 2000s, many of these cameras were installed with default passwords (like “root” with no password) or no authentication at all.

Why do hotels dominate this search result?

When you search this string, you aren't looking at a database; you are asking Google to return every unsecured camera that happens to be on a domain associated with lodging.
