i currently have a 4 camera NVR (ZMD-NH-SAE4) with 4 IP cameras ( ZP-IBH13-P).
I would like to expand this to 8 cameras. Can someone please advise if i can do the below
1) plug in additional cameras to a netgear/Dlink POE switch and then plug that into one of the ports of the NVR. Will this work can i add existing cameras this way?
2) Purchase a 8ch nvr and connect my exsisting cameras to it and additional camera. I would like to know which model of NVR can i purchase to be compatible with my exsisting cameras (ZP-IBH13-P) and secondly what other model cameras can i purchase that will compatible with the 8ch nvr ??
3) Are funlux cameras and nvr backward compatible with zmodo?
any help would be appreciated
