Tenda TEF1110P 8-Port 10/100Mbps + 2 Gigabit Desktop Switch With 8-Port PoE, 5.6 Gbps Capacity, 448K Buffer, 6KV Lightning Protection, 99W Power | TEF1110P-8-102W

PoE+ and Dual Gigabit Uplink Ports 1-8 support IEEE 802.3at and IEEE 802.3af PoE standard. It provides PoE power of up to 30W each port and up to 99W the whole device. The two gigabit uplink ports are capable for cascade connection of more devices. Up to 250 meters long distance transmission, beyond hundred meters transfer limit Due to the complex monitoring environment, when making cabling and networking ，it very often to encounter the problem of inadequate network transmission distance, the distanceof each camera terminal to the monitoring center is different, some only a few meters, some hundred metres, while others are more than kilometers.
