It's a Grandstream and I get half a green screen and jumbled video with Blue iris. It came with GSurf Pro which is fine for viewing but I haven't been able to use the other features due to, you guessed it, Chinese logic. For example, Trying to set motion detect to record a short 30 second video, which it's supposed to be able to do, has proven to be damn near impossible because I can't tell what the option actually do. The camera works perfectly with IP Camera Viewer but this free program has nearly zero features. I've tried a couple of others that didn't suit my needs also. Blue Iris is the only one that gives me the half green screen and jumbled video.
Synology Surveillance Station is the best I've found so far but you can't specify an external or network drive to save the videos to.
