Hikvision DS-3E0310HP-E (DS-3E0310HP-E(C)) — 8‑port unmanaged PoE access switch, optimised for CCTV and small network edge devices.

• 8 × 10/100 Mbps PoE ports (one Hi‑PoE port + seven standard PoE ports) and 2 × Gigabit RJ45 uplinks for uplink/backbone connections.
• Hi‑PoE support (IEEE 802.3bt) on port 1 up to 90 W; ports 2–8 support up to 30 W each. Total PoE budget: 110 W.
• Long‑range PoE mode for ports 1–8 (supports deployments up to ~300 m depending on cable and device).
• Built‑in intelligent PoE management (priority/VIP port, PoE watchdog-style features) to improve camera availability and power allocation.
• 6 kV surge protection on PoE ports for improved reliability in exposed or outdoor camera installations.
• Compact, fan‑less metal enclosure — wall or desk mountable for quiet, small-footprint installs.

Use cases: ideal for CCTV and small commercial/residential network edge deployments where multiple PoE cameras or devices require local power and two Gigabit uplinks for NVR/VMS connectivity.

Compliance & safety: product approvals published by the manufacturer include CE, FCC, IC, RCM and UL/CB/CE‑LVD; RoHS compliant. Check local requirements (for example UKCA) if required by your market.

Installation notes: requires 48 VDC power input (per Hikvision spec). Ensure total connected PoE load does not exceed the 110 W budget. Use recommended cable types and follow cable‑length guidance for long‑range PoE. For safety and warranty, install per local electrical regulations and Hikvision installation guides — for critical installs consider surge protection and grounding at the site.
