The Dahua 4-Port Fast Ethernet PoE Switch is specially designed for long-distance video transmission applications. The switch uses LD PoE technology to transmit power and data up to 250 m (820 ft). LD PoE extends transmission distances beyond the industry-standard 100 m, even with third-party PoE-compliant cameras. The switch provides four (4) 10/100 Mbps PoE ports and two (2) 100 Mbps uplink ports. The switch is also equipped with two transmission modes, Default and Extend, that are set by on-bard dip switches.
