Hey TTT,
I’m using Reolink RLC410 cameras. Imported direct from Reolink; I believe they running a special now at $45’ish each - I’m running 8 of those and two older Vivoteks giving me 10 cameras in total.

For $45 they are brilliant. They are definitely not perfect; day time performance is really good, so is static night time performance. The downside is that they change the exposure settings to give nice night time images, at the cost of framerate. In other words, if there’s a lot of movement at night the images can be blurry at times. I don’t really have a good example but it’s not been a serious issue for me to be honest.
The HikVision and Dahua starlight cameras are better, but they cost considerably more. Pick your poison. All this being said, I’m happy with the Reolinks especially as I’ve got LED lamps around my property in any case so I don’t have the exposure problems that others have complained about.

They do have pretty powerful IR lights built in, so much so that they shine a bright spot on the pavement where ambient lighting isn’t really present.
So yeah, I think they are good for what you pay for them and thus represent incredible value. Whether they will suit your needs vs something that costs 4 times more is debatable.
I didn’t integrate these directly into HA. I’m running Blue Iris on a windows server to record all the cameras. Blue Iris does talk to HA, so in my case I’m just pulling the images off Blue Iris and displaying them as streams in HA. That makes my camera choice HA agnostic. As long as Blue Iris can record them, HA will display them. And I can decide if I want to stream the main stream @5MP 15fps, or the substream at 640x480 30fps. In my HA dashboards I’m streaming substreams and those are realtime @ 30fps. Doing it this way the cameras are rock solid - I’ve not had a single issue with cameras dropping in HA at all. And because Blue Iris supports almost everything out there, it makes my life easier as far as HA is concerned.
The cameras support motion sensing, but it’s really not great. Too many false positives - but I knew that up front and that’s another reason I went for Blue Iris, which supports better Motion Detection and allows for 3rd party AI to do object and person detection. In fact, that’s one of the last outstanding items on the list I need to finish; integrating DeepStack AI with Blue Iris. There’s a massive thread about it on IPCamtalk and many people have gone this route. I’m just lazy 
Sho, that was a mouthful…
