Does it make sense to divide the local area into 2 segments?

Question

CCTV

There is a peer-to-peer network with 30+ machines on static IP addresses, 100 Mb.s. 3 NDVR video surveillance recorders are hooked up to the same grid (48 cameras and 8 sound channels in total). Several machines and NDVRs "go" to the Internet, or rather they are picked up from the outside for viewing. Does it make sense to divide the whole thing into two segments, i.e. enterprise network and network with DVRs in order to increase network performance? Internet channel one. There are no problems with it, the Internet is normal, but inside the exchange between machines is already very slow. All machines are running Windows XP 32-bit.

Answer 3

What is slow? Slower than 100 Mbps? Maybe the router is not coping, or if you have two routers, the channel between them is not enough?

Answer 4
