Network Access through a Router

In order to access the DVR remotely through a router (firewall), the user must open TCP

port for command level, live channels, and storage channels. The user needs to port

forward 3 ports in the router. These ports are found on the Network Tab of the DVR: 1)

Network, 2) Network Audio, and 3) WEB.
