MX Surge Protector RJ 45 Female Type (MX-2786)

Power surges aren't the only way sensitive electronics get fried - a long Ethernet cable run, especially one that goes outdoors or near a building's electrical entry point, can carry a voltage spike straight into a switch, router, or NVR through the data line itself. This connector sits inline on an RJ-45 run and clamps any spike down to a safe level before it reaches the device on the other end, the same principle as a surge-protected power strip but applied to the network cable instead of the mains lead. It's the kind of protection that's easy to skip until the first lightning season takes out a piece of networking gear, after which it becomes standard practice on every exposed run. Installation is as simple as any RJ-45 coupler - it just goes in the middle of the existing cable run.
