In real monitoring project, cameras are often installed outdoor or in a higher position, which also increases the probability of lightning shock toward the cameras and PoE switches. Therefore, some of the equipments may be damaged and even the whole local area network (LAN) may be paralyzed.

Tenda TEF11 series switches have professional lightning protection design – 6kV port and power supply thunder prevents. These two protection design can effectively inhibit the lightning current from the network cable and power supply, which is equivalent to add a security Walls to the entire network monitoring system. And the test standards are far higher than the requirements of the state CCC. In the thunderstorms, the monitoring network can also provide stable and reliable services to the monitoring network and ensure the normal transmission of the images.
