I haven't tried out the G2 yet but when it comes to standalone NVR from Hikvision, Dahua and Luminys, when the detection is done by the NVR itself then you will start noticing slowdowns when switching menus and loading video streams. I imagine it would be the same for the G2. Trying to have one unit do more things at once like accepting the video stream, sending the video and metadata to the hard drive for logging. Logging all the metadata so it could be searched.... Creating the thumbnail for everything and now having the G2 doing the metadata generation.... I guess that is why for ONVIF cameras the G2 won't do LPR or face. Not enough processing power.
There is never a one unit fits all it seems and that's why I run multiple units. Unifi Protect with its set of data. Hikvision NVR with its metadata that it is getting from the Hikvision cameras and a Dahua NVR with its metadata from those Dahua cameras. Yeah... pretty redundant but..... Here is a true story..... A year ago I had someone teaching their mother in law to drive and instead of braking, she floored it and smashed through my fence into the side of my house. The Dahua NVR went offline as that wall where the car came through was where it was housed cutting the power. The Unifi and Hikvision units are situated in other parts of the house and still recording. Ever since I have continued this concept. Better safe than sorry. Well.... I guess it didn't help that I have different brands of cameras and I wanted to see the metadata from each ecosystem from each set of cameras hence so many recorders....
