Do both ends of a network cable need lightning protection？
Network lightning protection
Lightning protection should be installed at both ends of the wire. Because if the cable on the production of inductive lightning surge, it is possible to break the equipment at both ends of the cable, if only at one end of the installation of the network lightning protection device, can only protect this end, the equipment at the other end of the cable is unable to protect.
Such as outdoor surveillance camera, a network cable connects the camera to the switch (LTE), if only a network lightning protection device is installed in the switch, it can only protect the switch's network port from lightning. To protect both ends, a network lightning protection device is connected in series at each end, with the output of the lightning protection device facing the switch and the camera respectively.
