The Hikvision DS-3E1518P-SI is a Layer 2 smart managed PoE switch built for reliable CCTV, security, and business network deployments. It combines high-speed Gigabit Ethernet connectivity with intelligent management features, allowing administrators to monitor network health, manage devices, and expand surveillance systems efficiently.
The switch includes 16 Gigabit PoE RJ45 ports for connecting IP cameras, access points, and other PoE devices, along with 2 Gigabit SFP optical ports for fiber uplink connections. Each PoE port can deliver up to 30W, with a total PoE power budget of 225W.
It supports advanced Layer 2 features including VLAN, STP/RSTP, link aggregation, SNMP, QoS, port isolation, and PoE watchdog, which automatically detects and restarts unresponsive cameras. It also supports long-distance PoE transmission up to 300m in extend mode and provides 6kV surge protection on PoE ports for improved reliability.
