Suggestions for outdoor smart camera that doesn't require proprietary app or connection to third-party servers

Can anyone recommend a weatherproof network camera that doesn't rely on any third party servers or a proprietary app? Bonus points if it can easily be attached to a bird feeder.

My main concerns are privacy, being able to use it when the company goes out of business, and looking at birds. Recording short clips and photos automatically when it detects a bird or motion is a plus.

I'm very technically inclined, but this would be for a nontechnical family member, so I could host Frigate (or similar) for them if necessary, but something that just connects directly to an open source app would be great.
