Information

One SPD into simulated lightning and network in one SPD, simulated lightning protection devices used to protect the analog cameras, network combo lightning protection of digital IP network cameras.

Mainly used for bolt of lightning protection.

Signal SPD series in the channel between the camera and, then what is the cause in one lightning, I analyse:

One principle of the SPD is to present high resistance when a low voltage open circuit State, when high pressure low-resistance short circuit to ground state. Internal use of multi-stage surge protection devices, such as discharge tubes, Varistors, TVS, resistance, SPD series is fitted with only one physical surface forms of lightning, and most of the main mine components are connected in parallel in the system.
