I've got a few cameras that require a crappy Internet Explorer only configuration "web" interface
I've seen several that require IE for in-browser AUDIO, but that's all. Every camera I've purchased can do configuration and video with any browser, and you can do audio with native apps on any platform (just not in-browser), going all the way back to Axis cameras just shy of two decades ago.
In fact, it seems ALL network cameras made today support ONVIF, so there's a compatible standard they all support (though maybe not in your browser of choice). There's nothing unreliable about any of them I've used, and I can't even remember user comments anything like that.
I'm completely unwilling to give a camera Internet access and allow it to connect to its vendor's website.
It's true they all OFFER a DDNS option, but you can easily turn that off. And recently a large number of the cheapest cameras require a proprietary phone app for setup, but there are still plenty with web interfaces that setup and work just fine with an incorrect gateway address or firewall rules preventing egress. I just bought a $30 one recently.
I'd much prefer a full Linux under my own control than a black box camera OS that wants an Internet connection and can be controlled by the vendor's website.
They're all Linux under the surface, you just need to look around for instructions on gaining access. Often it's just a one-line change in the firmware image before flashing to enable telnet access, or finding the serial port pins on the board, or similar.
