Excellent, thank you

Interesting view of storage

Hello sir, could you please explain the DVR architecture please

Thanks for the clarity of your post as always. I have a model of the wireless NVR which is Wnvr2008-B1 with 8 wireless ip cams of model: HCN-H23X6. The issue is two of the ip cams are out of the NVR's Wi-Fi range & neither the NVR nor the ip cam have a repeater feature. I intend to exerted the NVR Wi-Fi signal with my Tp-link TL-MR3240 router but the issue is how do I configure this to work! Three NVR has two different ip addresses: a. Basic: Network: static ip, ip address: 192.168.0.xxx, subnet: 255:255:255:0 gateway: 192.168.0.1 b. Network status: ip status: 172.20.18.xx, gateway status: 172.20.18.1, DNS1: 172.20.18.1 My question is which of these ip's do I configure the router to so as to be able to extend the NVR Wi-Fi to the two distant cameras. The ip cams "ip address" are within 172.20.18.xxx range. Thank you
