Tenda TEG1124P-24-250W    6KV Lightning Protection PoE Switch  is the only engineering switch In real projects, APs and cameras are often installed outdoors or at an elevated location, which increases the chance of lightning strikes on cameras and PoE-powered switches. The result is that individual devices are damaged when the outcome is light, and even the whole local area network is damaged. Tenda TEG11 series switches have professional lightning protection design - 6KV Lightning Protection for Ports and the power, and they have two levels of protection design respectively, which effectively suppress the lightning current from the network cable and power supply, equivalent to adding a security wall to the entire network monitoring system. The test standard is much higher than the national CCCrequest. In the thunderstorm, Tenda TEG11 series switches can also provide a stable and reliable service to the surveillance network and guarantee the normal transmission of the picture.    CCTV, Standard, VLAN and Isolation Operation Modes Offered Standard: The switch functions as a common unmanaged switch and all the ports of the switch can communicate with each other.  
CCTV: The port cache is optimized and PoE ports 1-8 have higher priorities over the other ports. All the ports of the switch can communicate with each other.  
VLAN: Ports 1 to 22 are isolated from each other, but can communicate with ports 23 and 24 (uplink ports) respectively.  
Isolation: Ports 1 to 12 and ports 13 to 24 belong to two different VLAN. This mode can be used to isolate supervision network and wireless network to make them not interfere with each other.    225W PoE power supply simplified wiring Ports 1-24 comply with the IEEE802.3af and IEEE802.3at power supply standards. The entire switch offers a maximum PoE power output of 225W, whereas each port offers a maximum PoE power output of 30 W. The ports can be used to supply power to and exchange data with APs and IP cameras.   Specifications: Network standards IEEE 802.3/IEEE 802.3u/IEEE 802.3ab/IEEE 802.3x/ IEEE 802.3af/IEEE 802.3atLED Indicator 24*Link/Act per device
