The 2nd generation Ubiquiti Networks Ethernet Surge Protector safeguards your outdoor non-PoE and PoE-based systems from voltage threats such as surges and electrostatic discharge events, which can render an entire network system inoperable. This protector is suitable for use with surveillance cameras, access points, and other Ethernet-equipped devices. Ubiquiti Networks has designed it with two surge-protected Ethernet ports that support Gigabit connection speeds. Furthermore, an external housing guards the Ethernet ports along with the surge protector from outdoor elements.
