A network security camera can benefit a lot from Power over Ethernet. The first important benefit is the saving in cost especially if it is an outdoor security camera because it is usually hard to find an available outlet outdoors. The cost of hiring an electrician to route a power line can add up if the security system will include a number of network security cameras. PoE allows the network camera to be moved anywhere without having to worry about the power supply since it is available over the Ethernet connection.
A network security camera connected with PoE also makes the entire security system more secure because the camera does not have to go out during a power outage. Most PoE devices will be connected to a server room from which they derive their network connection as well as power. And since most server rooms use Uninterruptible Power Supply, UPS, the network security camera stays on.
