CCTV - Remote Access over the internet
Modern CCTV surveillance digital video recorders (DVRs) have a network Ethernet port that allows users to access the DVR and connected cameras over a network, like a home broadband WiFi network. In the case of CCTV DVRs, all of the cameras are hard wired to the DVR using coax cable and the DVR is connected to the home broadband WiFi router that enables the video streams of the cameras to be viewed over a network using some type of client, such as a web browser on a desktop or laptop computer or using a mobile app from an iPhone, Windows or Android mobile phone. In order to make the DVR accessible remotely over the Internet, setting up port forwarding is necessary to route Internet traffic into your local network.
The routing of internet traffic requires a static address that never changes. There are two ways this is achieved; obtaining a static IP address from your internet service provider (ISP), which may be chargeable depending on the ISP, or using Dynamic Domain Name Service (DDNS). DDNS is a service that provides you with a host name to access your DVR remotely. This service is necessary if your Internet connection uses a dynamic IP address. Dynamic IP address means that the IP address that your ISP provides you with can change each time that you connect. The opposite is a static IP address which means that each time you connect your ISP always assigns you the same IP address.
