I have had this camera since the start of the year. It isn't usable in low-light at night in forced colour mode, unlike my 2MP Starlight. Its IR is however decently powerful.
I have a 1080p H265 PTZ in addition to this running in BI. I have an 8 core -16 thread AMD 2700x and it sits around 2-3% with the console open and will jump as high as 6% when both cams are recording and being viewed in real-time (both are on the highest bitrate settings at 15FPS). Watching a recording back in high-speed it will jump up to 10%.
One of my monitors it is hooked up to is a 43" 4k model. It looks really good full screen on that, but also still looks decent on my 2560 x 1080 ultrawide - the digital zoom on top of being fully zoomed optically is quite usable.
