Network Access beyond a Router
In order to access the DVR remotely beyond a router (firewall), the user must open TCP
port for command level, live channels and storage channels. The user needs to open 3
ports on the router; the DVR port 5445, 5446, and the WEB port 80.
If this port is not opened properly, the user can not access DVR beyond a router.
