There is no limit on the number of remote users / clients that can access a NUUO PC based DVR or Hybrid NVR. This applies to NUUO DVR cards, NUUO IP camera software, and hybrid PC based systems. however there is a limitation on the number of video streams that the software supports. For remote live view the limit is 128 video streams and for remote playback is the limit is 64 streams.
For example, if you have 32 security cameras, max 4 users can remotely view all of the cameras at the same time. If I have 16 cameras, max 8 users can view all cameras.
