Security cameras that run over a standard IP network are becoming more of a common place in the home and in a commercial environment, partly due to their ease of setup and the seamless integration in to an existing backbone, but also the ease of scaling the system up to the levels that we find in our supermarkets [for example] where tens, if not hundreds of cameras are connected in to a single environment. The additional benefit of utilising IP cameras though is the ability to connect into the system from a remote location and use it as though you are on the site itself. This is not where the selling points end though; power delivery to the cameras is another factor that has to be taken into account and with so many cameras in some instances being required, or the position where they required not the convenient for the purpose of mains power, the capacity to power the cameras directly from the network switch and through a single cable with the data to the camera, makes the speed of installation and the ease of expansion much quicker and easier.
