All networked productswhether computers, phones or network camerashave two things in common. First, they require a network connection; and second, they require power. The network connection is normally provided via network sockets at the location of the product, while power typically means "find the nearest power socket."

However, simply plugging networked products into the nearest wall socket creates a number of problems. A primary concern is the location and number of available AC outlets. AC outlets are often in easy-to-reach locations, so employees may unknowingly unplug cameras to use the AC outlets themselves. In addition, cameras are often installed near the ceilingin areas where power outlets are generally not available. Retrofitting so that AC outlets and electrical wiring are in the "right" places can be extremely difficult, and it can add significant cost and time to the installation process. Also, in the case of a power outage, it can often take a long time to locate the correct fuse or circuit breaker in a large building.
