opening two doors nvr

[ste92]

hello everyone, in a house I have a nvr hikvision with ip 192.168.1.10 I see with hik-connect and also with ivms-4500 android with set ip static and with open ports on the router:
2015 http
8000 servers
1554 rtsp
also enabled upnp.
in these days I have to add another nvr in another house but with the same network 192.168.1.xxx, for the moment I will leave the same ip class so I will open the doors and give the NVR the calsse ip equal 192.168.1.20
so I will open a different http port but the other two server and Rtsp ports can change them or do I have to keep the 8000 and 1554 ports?

Opening ports can be very dangerous. (+UPNP lets any computer or device to open ports so it not good unless really necessary (Source))

If you want to open ports:
If the first uses ports 2015, 8000, 1554 try 2016, 8001 and 1555 for the second one.

Opening ports is bad.

I understand, thank you. I will use hik-connect to see the hikvision cameras without opening the ports on the router
