To view cameras remotely from a computer or a mobile devise, one will need to connect the DVR to an internet router. Obviously not all DVRs have the capability of doing this, so the DVR must be specifically designed to support network communication. The cameras can be accessed through the IP address. This IP address needs to be fixed or static and is obtained from an Internet Service Provider. Once the system is up and running, all one needs to do is to enter this fixed IP address into the address bar of a normal internet browser, and after entering the username and password, the live images from the camera can be viewed. Although recordings cannot be viewed in this way, since the DVR software would be required, there is still a way that this can be done.
