Does any one know of a privacy focused security camera?

I live in a rough neighborhood and am concerned about theft, but I have 0 faith or trust in companies like amazon.

If I want a security camera that I can check remotely, but I want to own my data and have complete privacy (no snooping by the company, no ability for them to give my data to some one else).

Do I have any options for this other than completely rolling my own?

Personally, I moved from BlueIris and I've been incredibly happy with Frigate which is configured to pull from my local IP cameras - none of which have direct access to the internet: https://github.com/blakeblackshear/frigate

You can check in via browser assuming you have some method of accessing your local network. Paired with a google coral device (or a beefy CPU) alongside local storage, it also has the ability to detect objects in real-time which often is a feature that requires video processing on a company's server.
