Yep
Now the question is, being as they worked initially with a 10.1.1.x address prior to this event, is his internal lan/router assigning the 10.1.1.x or is he feeding the switch from one of the PoE ports in the NVR which is assigning a 10.1.1.x ?
Yes, initially I did plug them in the NVR's built in POE switch then moved them over to the BV-Tech POE switch.

If those cameras came up with a 10.x.x.x address they were either not new or had been powered up to an NVR. The default, fixed, address of Dahua cameras is 192.168.1.108.
Yes they were initially powered by the NVR, and then I moved them into the garage to the BV-Tech Poe/POE+ switch.

you may have to use the dahua toolkit to change the cameras ip to the range of your switch and you will have to do one at a time like others have said

I have an Apple Extreme router 4th generation. I don't understand what "outside the scope of the DHCP pool" means.
Can you explain?
@tubac, you're getting plenty of good help from others, but let me try to answer that question:

The router has a range of IP addresses it will assign to devices that are set to DHCP (Dynamic Host Configuration Protocol) mode, meaning they can change and are NOT static. That range of addresses is generally called the "DHCP Pool". When you decide to assign a static IP to any device that operates in the same subnet as the router's LAN you should use only IP addresses that are OUTSIDE of that DHCP pool range.

The D6400 DHCP settings are the following :
192.168.0.2-192.168.0.254. Pretty much the whole enchilada
Being that your router is probably 192.168.0.1 on the LAN, then if the router's DHCP pool is 192.168.0.2 to 192.168.0.254 as you stated above, then there is NO IP outside that pool for YOU to use as static IP's.

I would log into the router at 192.168.0.1 and change that pool like from 192.168.0.2 to 192.168.0.99; that leaves 98 IP's for the router to use and 154 (192.168.0.100 to 192.168.0.254) for you to use as static IP's for cam's printers, etc.

Do you recall where you saw that?
It's not correct.
I think BIGREDFISH says that about connecting New cams to NVR's. Because they will assign a 10.10.10.xxx address I believe.
If you're replying to me, then I was speaking general network terms when it comes to a router, DHCP, static, etc. and answering tubacs statement about his router...none of that changes what bigredfish stated about an NVR.

Clear and concise, thanks!
So all of my cams are in the 10.xxx scheme except two which are in the 192.xxx scheme. I have 13 cams in all. How would limiting the DHCP server scheme affect my setup?

All you need to do is limit the IP range in DHCP, say from192.168.0.1 to 192.168.0.99. Then use the Dahua config tool to change the cameras to any address in the 192.168.0.100 to 192.168.0.24 range. There is no need to have 255 addresses available for DHCP on a home LAN.
