I have a Reolink 410 running that I purchased before I really knew what I was doing and before I started running
Blue Iris. It does work on Blue Iris, although the stream can be finicky at times (probably because of the i-frame issue). What I mean by finicky is that the stream will fail sometimes after I mess with the "camera" settings in BI. In fact sometimes it even stops working when I mess with other cameras in BI too. I usually have to reboot the physical camera for it to start working again. However, once it is running it is stable.
That being said, I would never recommend that someone buy a Reolink camera. I use mine in a non-critical role and it works just fine, but I would not want to trust it in a critical role (ie providing ID quality images) in my system.
Here is my take on the whole situation...... If you feel compelled to have cameras in the first place, isn't it worth the extra money to get a camera that is universally recommended on forums like this. I'd rather have fewer cameras that actually provided a usable image (especially at night) than more cameras that only provide a false sense of security. If a camera can't provide clear enough images to properly ID a subject, the camera is ultimately a failure. In the opinion of most "experts" on this forum, the Reolink models aren't going to provide ID quality images at night and I can confirm that has been my personal experience as well.
