Access DVR from remote location
To access your DVR from a remote location, you will need to configure your router's setting, so it forwards the port(s) necessary to the DVR. Way of setting up port forwarding is varied depending on the brand and model of your router.
For Cat. A products, only the HTTP port needs to be forwarded. For Cat. B products, both control port, data port and HTTP port are necessary.
Once port forwarding is succeeded, you will be able to access the DVR from a remote location with you public IP address. If you are using Dynamic IP, it is strongly recommended that you register a free DDNS account, so a hostname will be pointed to your floating IP address automatically.
