There’s no reason to try and salvage a ring camera. Their business model is subscriptions and data collection; I’m not aware of any projects to flash them with custom firmware, and my guess is they’re locked down hard to prevent it because that’s their entire revenue model, you’re free to keep looking but I’d bet it’s a dead end or at the very least much more than an afternoon project.
Get a Wi-Fi reolink and connect it to an ONVIF capable NVR. You can use a paid solution like blue iris on a Windows machine or there’s plenty of free options for any OS of your choice. You can probably directly access the feed by navigating to the camera IP but I’m not sure, I don’t use mine that way. Without some kind of NVR software you won’t get a lot of the features people like such as notifications and two way talk, object/person recognition, etc.







Wireless cameras offer an easier vector for people to get into your camera feeds. Biggest risk to this is a poorly secured network in the first place, but the risk is still there.
Also, wireless is going to be inherently a worse quality video stream, and constant video traffic being sent over your Wi-Fi bogs down your entire network.
All that being said Wi-Fi cameras are just fine and as long as you have strong Wi-Fi security you’re really not at a real risk unless someone very savvy is specifically targeting you, in which case you’ve got bigger problems.
I have probably a dozen cheap wireless cameras in my house (to keep an eye on pets) and I have them spaced over two access points and honestly I don’t notice a difference on my Wi-Fi at all, but I’m sure it’s worse than if I didn’t have them. All my exterior cameras are wired, but that’s more because I want better quality streams and I’m running a wire anyways so might as well be PoE. Only exterior wireless camera I have is my doorbell but that’s because I didn’t want to run a new wire to it.
Overall wired cameras are much better quality, but they’re not as convenient. Make the decision for yourself based off of your priorities. Real tough to get a wireless camera with the fidelity needed to capture license plates clearly, but if you don’t need that then why worry about whether your gear can achieve it or not?
