Thanks for your quick reply. Haha!
I've disconnected the cameras from the old CCTV system and they are now only streaming directly to NCS
I'm using NCS 18.104.22.168
Yes the FPS is the embedded one in the bottom corner.
Total CPU load is about 15% with NCS using about 11% of this.
The client is set to the highest quality and quickest frame rate.
They are Hikvision cameras, DS-2CD2032-I
I tried ONVIF at first and used the auto detect and then tried changing it manually using the "network camera" tab. Using RTSP Main Stream
Sill showing a very poor frame rate
