PoE switch for surveillance - Extralink CERES Extralink CERES (extralink ceres switch ex3906 8x) is a 10-port PoE switch with 4 modes of operation: AI QoS mode, AI VLAN, AI Exten and smart power mode. AI QoS mode is ideal for surveillance applications, ensuring smooth video by processing with the highest priority video data. Port separation using the VLAN function The extralink switch has AI VLAN mode, so ports 1-8 are isolated from each other, which helps to effectively suppress starvation storms and improve network performance. Powering cameras up to 250 meters and monitoring device performance in real time In AI Extend mode, ports 1-8 can effectively transmit data and PoE power over a distance of up to 250 meters, which is ideal for surveillance systems and when powering cameras or access points. In AI PoE mode, the switch automatically detects the operating status of the connected device, when it finds that the device is working incorrectly, it automatically restarts the device. Key features: AI PoE mode: automatically detects an unresponsive device, shuts down PoE power on the port in question and restarts the power supply AI QoS mode: adjust the priority of video data packets, making video surveillance transmission smoother AI Extend mode: ports 1-8 support power over 250 meters (use Cat. 5e or Cat. 6 cable) Supports IEEE 802.3af/at standard AI VLAN mode: isolate ports 1-8 from each other Power circuit protection for protection of terminal equipment Auto MDI/MDIX support Store-and-forward Fanless design - energy savings Power saving function on unused ports
