Tenda TEF1109P 9 Port (8-Port PoE) 10/100Mbps Desktop Switch

Due to the complex monitoring environment, when making cabling and networking, it is usual to encounter the problem of inadequate network transmission distance, the distance of each camera terminal to the monitoring center is different, some are only a few meters, some are a hundred meters, while others are more than kilometers. Tenda TEF11 series PoE monitoring switches, exclusive patent network extension technology, use the common existing twisted pair, can support 250 meters data transmission, break the transmission limit of the existing twisted pair only for one hundred meters; Providing gigabit linked SFP port, can meet the demand of transmission to a few tens of kilometers. In real monitoring projects, 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 equipment may be damaged and even the whole local area network (LAN) may be paralyzed. Tenda TEF11 series switches have a professional lightning protection design ac 6kV port and power supply thunder prevent. These two protection designs can effectively inhibit the lightning current from the network cable and power supply, which is equivalent to add 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. Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. It provides maximum power supply of 30W to each port and 58W to the whole device.
