JetNet 3810G

Key Features:

The JetNet 3810G is an Industrial PoE Boost Switch designed to extend the high and low bandwidth data through fiber uplink connection for flexible distance mobile surveillance applications.
The switch make use of its built-in Korenix patented vehicle PoE technology to convert DC 12~24V from a battery to DC 48V for 8 PoE ports, offering up to 65W power to make the deployment of standard PoE IP cameras feasible on buses, ships, carriages.
• 8 10/100 TX PoE plus two 10/100/1000TX uplink ports
• Vehicle PoE: DC 12V~24V input, deliver 8 port PoE @48V
• 802.3af compliant PoE: Total power budget is 65W* with max. 15.4W per port
• Two gigabit Ethernet ports for larger uplink bandwidth of surveillance
• Support QoS for optimizing video and VoIP stream
• Fault relay for active warning of port failure
• -25~60℃ operating temperature
