Commercial PoE switch is 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 is also equipped with two transmission modes, Default and Extend, that are set by on-bard dip switches.
