Tenda TEF1218P switch supports 16 Po E ports, which can supply power to most powered devices through 8-core Ethernet cable, & the total Po E power can be up to 230 W while each Po E port can support the maximum Po E power of 40 W. Po E switch with 6KV lightning protection is the most suitable choice for surveillance private. In reality surveillance project, cameras are generally installed outdoors or in high position, which makes the cameras & switches under the risk of lightning shock. As a result of the individual equipment damaged, or lead to the whole local area network (LAN) paralysis, Tenda TEF12 series switches are designed with professional ports & lightning protection up to 6 KV, with two kinds of protection design respectively & effectively restrain the power of lightning from cable, which equivalent to give the entire network monitoring system with a security fence. The test standard is much higher than the national CCC request. In thunderstorms weather, it can also provide monitoring network stable & reliable service, protecting the images transmission to be normal. Up to 250 meters long distance transmission beyond hundred meters transfer limit In the complex surveillance environment, when making cabling & networking, it generally encounter the problem of inadequate network transmission distance, the distance of each camera terminal to the monitoring center is different, some only a few meters, some hundred meters, while some are more than kilometers. Tenda TEF12 series Po E monitoring switches with exclusive patent network extension technology & using the common existing twisted pair, can support 250 meters data transmission & break the existing twisted pair hundreds of meters transmission limit. Providing gigabit linked light port can meet the demand of transmission to a few tens of kilometres. The Po E total power is 230W, 16 port power supply full load is enough The switch total output power is 230W&65292; which can support 16 ports power supply full load. Po E power supply can meet the needs of HD camera & other power supply equipment. With eight core power supply design, network power consumption reduced half, which ensure the camera get electricity & stability.
