Setup a DMZ Zone for a Q-SEE CCTV in a SONICWALL to give access to a remote laptop that could be in any domain

You could certainly put the CCTV system in the DMZ if you wanted to - this would also officially segregate it from your LAN and would require some rules to allow connection from inside your network.
If the CCTV system has authentication, then perhaps the easiest way to accomplish this would be use NAT/PAT to map a public IP address to the private IP of the CCTV system, and have the traveling laptop access the CCTV system via the public IP.
Even if you put the CCTV in the DMZ, you'd still need to do some amount of port forwarding/NAT translation to make it accessible from the external Internet.
If your laptop user connects to your network via VPN, then you could leave the CCTV system where it is.

I was thinking about the VPN too...never done a NAT/PAT configuration.

Re: NAT/PAT - not too bad on a Sonicwall. The wizard's actually really good and will do most of the heavy lifting for you.
However, if you go the VPN route, you won't have to do anything - as long as the laptop user is okay with getting on the VPN before they can view the cameras.

I have a Sonicwall Firewall, so if I wanted to set this up correctly using a VPN, I would have to do it using a VPN Tunnel and not  a Site to Site configuration correct?

I am trying to setup the Sonicwall as a VPN and having issues doing it thru a POLICY TYPE Tunnel.
Can you help with this as well? Thanks.

Thanks that be all. I called Dell for my SonicWall, they were able to help me setting up the VPN. :)
