commercial grade power over ethernet (PoE) network switches transmit both power and video over a single Cat5e cable run which saves you money by not having to run individual power lines to each of your cameras. Cat5e Ethernet cable is lighter and easier to pull which further cuts down on your installation costs. This also adds an additional layer of freedom for your camera placement as they are not forced to being installed near power terminals which lets you monitor your high risk areas precisely how you want to.
