Tenda TEF1110P 8-Port 10/100 Mbps 2 Gigabit Desktop Switch TEF1110P-8-102W has network extension technology. Based on the original twisted pair, it can support up to 250 meters of long-distance transmission, breaking a hundred meters transfer limit. With 6KV lightning protection, it is the real monitoring private switch. Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. It provides a maximum power supply of 30W to each port and 99W to the whole device. Meanwhile, it provides a dual gigabit uplink port to meet the needs of more equipment cascading and access. Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. Machine PoE maximum output power of 99W, the single-port maximum output power of 30W. The two-gigabit uplink ports are capable of cascade connection of more devices. 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 TEF12 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; Provide 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 – a 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 adding security Walls to the entire network monitoring system. And the test standards are far higher than the requirements of the state CCC. In thunderstorms, the monitoring network can also provide stable and reliable services to the monitoring network and ensure the normal transmission of the images.
