First, network structure:
TP-Link Archer C5 (gigabit) running as DHCP server for LAN
2 personal computers, wife's and mine (DHCP), 1 file/backup server (static IP), 1 DVR server (static IP), assortment of cell phone/tablets also connecting to LAN.
4-port 100Mb/s PoE switch for 2 network cams connected to LAN through TP-Link. Network cams have static IPs.
I'll try to work on a map of the layout in the next few days.
DVR server has 2 NICs. One is connected to the LAN and the other is unused. I was wanting to offload the network traffic of the 2 network cams from the TP-Link to the unused NIC in the DVR server and I'm not sure how to approach it. I connect to the DVR server for administrating via RealVNC and the couple times I tried to configure the NICs for this, I had to get out a kb/mouse to undo what I did...
I had tried bridging connections and that went nowhere. I tried to configure the unused NIC as a DHCP server with a different IP than my other network. (NIC in use 192.168.0.112, available NIC I tried 192.168.1.1 and got an error that it wouldn't work.) Seems like a decade or more ago there was an option for network sharing in XP but cant find it in Win7.
The main reason I want to do this is to try to eliminate glitchiness observed with live video and archive playback of network cams, since everything seems to be going through the DVR and TP-link twice, then to my PC for viewing on client software. The archive playback problem may not be network related since recorded video is what it is, but playback is over the network while recording is still ongoing and network cams are still going, so it may be network related.

You can see my DVR's hardware could use an upgrade, CPU/RAM/GPU possibly barely adequate. But before I added the network cams and eliminated a few analog cams everything ran as smooth as mother's butter with 9 total cams. That's why I'm thinking the glitch is network congestion. There may also be a way to configure the current config for better efficiency I'm not aware of. I plan on eventually eliminating the analog cams one by one, and also plan on more storage for the DVR. I want to do another hot swap bay and run RAID-1 like I have set up on the file/backup server. I really hope someone has done this before lol. I'm certain there will be more details that may be needed, and it may be a couple days before I can reply because of the holidays. Any input anyone has will be warmly welcomed and greatly appreciated. Merry Christmas-eve by the way.
