Tenda TEF1109P 9 Port( 8- Port PoE) 10/ 100 Mbps Desktop Switch( 63W)
Due to the complex monitoring terrain, when making cabling and networking, it's usual to encounter the problem of shy network transmission distance, the distance of each camera terminal to the monitoring center is different, some are only a many measures, some are a hundred measures, while others are further than kilometers. Tenda TEF11 series PoE covering switches, exclusive patent network extension technology, use the common being twisted brace, can support 250 measures data transmission, break the transmission limit of the being twisted brace only for one hundred measures; furnishing gigabit linked SFP harborage, can meet the demand of transmission to a many knockouts of kilometers. In real monitoring systems, cameras are frequently installed out-of-door or in a advanced position, which also increases the probability of lightning shock toward the cameras and PoE switches. thus, some of the outfit may be damaged and indeed the whole original area network( LAN) may be paralyzed. Tenda TEF11 series switches have a professional lightning protection design †“ 6kV harborage and power force thunder help. These two protection designs can effectively inhibit the lightning current from the network string and power force, which is original to add security Walls to the entire network monitoring system. And the test norms are far advanced than the conditions of the state CCC. In the showers, the monitoring network can also give stable and dependable services to the monitoring network and insure the normal transmission of the images. Anchorages 1- 8 support IEEE802.3 at and IEEE802.3 af PoE standard. It provides maximum power force of 30W to each harborage and 58W to the whole device.
