1.how can i access these camera from our network(its not pinging from 172.17.x.x)

2.if need to do port forwarding ,how can i make it in network switch

3.As i described,14 camera are directly connected switch without any nvr,so where the recording is saving.

Thanks in Advance

Are the two switches in the two buildings connected?

Then, if set up properly and if NVR supports that many cameras, the recordings from all cameras should be saved to the same NVR.

As for port forwarding, you don't set that in the switch.

You set that in the router that connects your LAN to the internet.

Then, when outside the network, you access your routers external IP adress.
