External access with DDNS

Most software has advanced, IP cameras feature a DyDNS. With this feature, the IP address outside reported. For example, a free service such as www.no-ip.org DDNS settings, no matter if a member of the IP address of the camera reports for this service. So you do not know the IP address you can access through the address. Similar applications have software for ADSL modems. In general, the internal network IP address takes the cameras with the address of the DDNS update does not make sense. If you have an ADSL modem with a network connection to your environment, the camera is a static IP address to identify the most logical. If you have a static external IP no problem with ADSL connection. Just need to open port ADSL modem. When asked when opening the server address, port address of IP camera should give. We then end of the port by entering the IP address of the ADSL modem (eg http://178.10.20.30:8560) you can watch the camera images remotely. Enter a static IP if you connect the ADSL modem, ADSL DDNS settings. Then, without paying the least attention, regardless of IP address, the address where the service (eg http://pcnet.no-ip.org:8560) camera can image.
