i have one camera, color 4kt-180 on a NVR5216-16P-4KS2E that records and plays back at 1fps and i cant workout why, it shows fine on the monitor in real time, all the settings seem ok. all other cameras are just normal color 4kt cameras and work fine.
how to fix? been like this since i put the cameras on.
