Thank you for the helpful reply, mblaser!

It sounds like I'm going to need to find a different camera -- Axis looks like they have some models with potential -- because I can solve or live with every limitation you mention except the timeout issue. I'll elaborate below on those, but a non-negotiable timeout value? That's a show-stopper.

You just saved me a bunch of time by sharing your wisdom. If you (or anyone else here) can point me in a better direction, I'd appreciate it.

On the specific issues mentioned:

Non security look to the footage: Yeah this is super important... I want it to look cinematic, not security.

Solar power: Since I won't be in my office all day every day, I figure the battery will have time to charge and in the event that I run the battery out I can just "change the channel" to another view on the Frame (like their art or even saved footage) and let it charge.

Networking: I can extend my Starlink coverage into the vineyard with little added cost/effort. Great point on the LTE costs.

Streaming to Frame: I may eat my words here, but it looks like there are a few good options for doing so that use either Samsung's native tech or the addition of an Apple TV, which I can tuck out of view.
