Agreed, transport encryption is the term to use for this model which is a great model anyway.

You can use e2e if the data-at-rest (e.g., video) file(s) are also 100% encompassing the encrypted in both the camera and the remote server, as well as the mobile app and remote server.

From the client-side, this E2E means no raw data are exposed over network nor in remote storage and that keys are required to view the raw data at either endpoints.

In today's parlance, the undefined portion of E2E is whether the local storage is encrypted as well. Some will argue on this point. Future may (and should) tighten this E2E as well.
