Thanks for your inquiry.
According to your project details, I have attached a file for your reference.
1. It is better that your camera is all IP camera, (also supports 1080P), if your camera is an HDMI camera, you need plus an HDMI to Data convertor.
2. 6 IP cameras use one router to connect our transmitter by network cable RJ45. The receiver also has RJ45 output to an NVR, NVR has HHDMI output to your monitor.
3. It is better to use 4 또는 6 카메라. if using 8 cameras at the same time. the video speed will be slow. It is easy to understand if you have 8 PC to download 1080p video, then the net speed will be slow.
4. If the transmission distance is longer and longer, the net speed will be slower and slower. If the work environment is bad, we will change more strongly PA (전력 증폭기)
5. At our test video, we have shown you that the person can operate the PTZ control at the receiver, then the zoom camera at the transmitter can pan or zoom.
