Frigate recently bundled an instance of go2rtc which can connect to Reolink cameras via http/flv and re-stream as RTSP. This solved my issues with Reolink.

go2rtc also works nicely for on demand transcoding of my H265-only cams to H264 to view the live stream in Firefox.

I use blueiris which barely works because I'm overloading it with 9 reolinks at 4k. I'd like to figure out my bottleneck but it works enough barely that it's not worth mucking with it.

Curious - does having 4k (compared to 2k or 1080p) make a huge difference for security cameras for surveillance on a property like a home?

It depends on the application. 4K on a camera that's high up and covers a lot of area is good because you see more pixels on objects. Also stuff like identifying people's faces or license plates. 4K for a camera that is close up, like say a doorbell, is IMO less useful.

4K to FHD is the difference difference being able to see someone’s face, or not. Or being able to read a license plate, or to.

Digital zoom also can be more useful.

What I’ve learned from clients is to get the best resolution cameras you can and PoE cameras only if the use case remotely is safety or security.

Mine are all high up in second floor so it does make a difference.

Have you tried Neolink to make Reolink RTSP little better?

I have a reolink E1 hooked to my Homeassistant, the rstp stream seems to crash from time to time. I had never heard of neolink, would it help on this case?
