Wired security is the most traditional and used primarily on larger properties. Evidenced by their name, wired security, these systems require cables for power, internet connection, and video transmission. A cable runs from the camera to a recorder, which then connects to your router. There are two choices for how a wired security system is powered, a separate power cord or one POE cable. POE or Power Over the Ethernet enabled systems only require one cable which provides both power and internet connection.
