Do you still have the Reolink cameras ? There have been firmware updates to enhance compatibility with BI5, and Pogo knows a thing or two about getting them working too. I don't think they will be very good in the dark, but they can fill in gaps.
I haven't bought any cameras for a few years, but I think I hit the sweet spot with 2MP 1080P cameras as they show well on a TV screen. They are Dahua starlight cameras, and they do indeed see in the dark, with or without IR Leds. I see the constant rush for more MP, but all that does is fill your hard drives faster. All you need to do is identify things or people. I may have a problem replacing them when they fail, but my first one has been working well since 2018. I note that when I was asked for footage by the local Police, they required the original files, so compatibility is key.
I do have the Reolink POE doorbell, and that is rock solid with BI5, although the audio is poor compared to my Dahua drive cam.
Note: I have read elsewhere that this forum is biased towards Dahua cameras. I'm an Engineer. If I find something that works I will buy more of it and tell other people. I have never had a free camera, and I pay for BI5 support annually
