Hi Cynthia,
I think you missed the point of Daniel's post.
He was interested in connecting to the camera feed via 3rd party software when it is connected into the NVR directly.
That saves the need for a second PoE switch.
As I mentioned above, it would require the NVR to map the ports through its NAT firewall.
You mentioned in August that you were talking to your R&D team about this. Any progress?
Thanks! got it sorted. I posted in my thread.
