Thingino doesn't support cams with ARM processors, we only support the chips made by Ingenic (which are a MIPS superset they call Xburst). We have a number of 4 megapixel (not 4k) devices we support, and are in the process of adding support for the next generation of Ingenic chips (Xburst2) which will bring up support for 8 megapixel (4k) devices.

We're also focused mostly on the less expensive models, because they're obviously within reach for a lot more folks but also they're almost always subsidized by the expectation that a discounted purchase price is made up for by the vendor's cloud subscription. You can get a LOT of great camera models for a low price.

I will say that there is a story about Hikvision that would likely steer most folks away from their brand.. it's bad enough that Google won't index it... With that said, I don't believe anyone should be trusting any third party with their video data in the first place...
