TRENDnet 12-Port Gigabit PoE+ Smart Surveillance Switch, TPE-3012LS, 8 x Gigabit PoE+ Ports, 2 x Gigabit Ports, 2 x SFP Slots, 110W PoE Budget, Managed Switch, Long Range PoE+ up to 200m (656 ft)

DEVICE INTERFACE: 8 x Gigabit PoE+ Ports.
4-Digit PoE LED display (total power budget, available power, consumption per port).
SMART SURVEILLANCE MANAGEMENT: These managed ONVIF switches are optimized for the surveillance industry.
surveillance mode provides a graphical dashboard interface with detailed information about the switch and each connected device..
LONG RANGE POE+: Long distance PoE+ networking up to 656 ft./200m away at speeds up to 10mbps.
INTEGRATION FLEXIBILITY: Managed switch features include access control lists, VLAN, IGMP snooping, QoS, RMON, SNMP, and syslog for monitoring and flexible network integration..
POE DEVICE ALIVE CHECK: Feature that attempts to recover an unresponsive PoE device connected to the switch. If a device(ex. PoE camera) is unresponsive, the switch auto-reboots the PoE port attempting to recover the device.
POE POWER: Each PoE+ managed ONVIF switch supplies up to 30W of power per port and data over a single Ethernet cable to PoE devices.
HARDWARE DESIGN: Provides gigabit PoE+ ports, SFP slots for fiber connectivity, and a 1U 19” rackmount design with brackets included.
SURVEILLANCE MODE: ONVIF switches are optimized for the surveillance industry, provin....
