Thanks for the answers but the problem is that I already have all the cameras connected on the same network (everything is on the same switch) and I also tried all the possible ports configured in the hikvision different protocols but nothing (80, 8000, 554, 443).
Can it be that hikvision video format is not compatible (not just a resolution problem) due to parameters like variable bitrate, frame type, etc...
Can somebody post his configurations?
It would be really helpful.
