The AW-FET-060C-065 quipped with DIP switch provides EX mode. Especially designed for IP Surveillance application, the camera provides standard 802.3af/at PoE functions in EX mode, while EX mode transmits data & power on one single cable up to 250m via EX ports for long-reach PoE IP cameras. The Commercial series adds an extra 20% range of input voltage tolerance (280VAC 4hrs, 300VAC 1 min), lightning surge protection of AC power & PoE surge protection to prevent the damage caused by unstable outside AC power, lightning surges, and power spikes. These unique features reduce costs associated with the replacement of damaged units.
