Visit via port mapping in the router configuration
(http://suvideo.gicp.net:84) |
1. Set the IP address, subnet mask, gateway, etc. of the DVR the same way as the network settings of the LAN.
2. Set the port mapping in "virtual server" in "forward rules". Enter 8000 in server port, fill in the IP address and enable the service. (80 Port mapping should be added if you visit via IE browser)
3. Apply for a DDNS(www.oray.com/www.dyndns.org), and set the DDNS of the router.
Enter DDNS, user name and password in the host side of the DVR |
Visit via
IE browser (http://suvideo.gicp.net:84) |
1. Enter the IP address of the model in the address field. If the http port is altered, the new port number should be added.
2. A control should be downloaded and installed from the DVR first, otherwise, there will be no response after entering the name and password. If that happened, Select "Security" in the "internet options", and enable all of the ActiveX settings "Custom Level". Restore the settings after the access to the DVR. |
