Take a look at https://openipc.org/ and choose a camera from their supported list.
But above all, it's exactly this that's the biggest problem. I'd wager like 75% of devices have an OpenIPC capable chipset. But there's only rudimentary tracking of what devices have what chipsets.
And it's unknown what other wrinkles folks might run into if they do get a device with a valid chipset. Most should just work, but a number will also require more embedded hacking.
Such an amazing project though. Stunningly wide support for a huge array of chipsets.
I'm also curious if anyone has found cameras available through Amazon or Ali which guarantee support.
