UTT S1242GP is a gigabit AI PoE switch, with 24 10/100/1000Mbps PoE ports with 2 Gigabit SFP Ports. S1242GP can carry power to an IP camera, wireless AP, wireless bridge, and IP phone. It is with 4 working modes, In AI VLAN mode, 1 -24 ports are isolated from each other, which can effectively restrain network storms and improve network performance. In AI Extend mode, the effective transmission distance of 1-8 ports can reach 250 meters, which is suitable for remote monitoring and power supply. In the AI power supply mode, the switch automatically detects the working status of the PD device and finds that the device is abnormal automatically restarts the device. In AI QoS mode: the video data will be processed preferentially when the device is congested to make the video smoother This switch supports IEEE802.3af/at, auto identification power device, so don't worry it will destroy the private standard PoE or non-PoE device.
