📦 Device Overview: Hikvision DS-3E1518P-EI/M (Enhanced Version)
🔌 Port Configuration
-
16 × 10/100 Mbps RJ45 PoE Ports
→ These are Fast Ethernet ports (not Gigabit) for powering PoE devices like IP cameras. -
2 × Gigabit Combo Uplink Ports
→ Usually means 1 × RJ45 + 1 × SFP port combo — you can use either copper (RJ45) or fiber (SFP) for uplink, not both at once.
⚙️ Technical Features
| Feature | Description |
|---|---|
| Switch Type | Layer 2 (L2), Smart Managed |
| PoE Standards | IEEE 802.3af (15.4 W) and 802.3at (30 W) |
| PoE Power Budget | 230 W total – suitable for 7–8 devices at full 30 W |
| Max. Distance | Up to 300 m PoE in Extend Mode (reduced speed, typically 10 Mbps) |
| Surge Protection | 6 kV on ports |
📡 Smart Management Features
| Feature | What It Does |
|---|---|
| Visualized Topology Management | Displays network map showing device relationships and status – often via Hik-Partner Pro or iVMS software |
| Network Health Monitor | Checks for abnormal bandwidth, link status, and PoE errors |
| Real-Time Alarm Push | Push notifications for camera disconnection, PoE overload, etc. – works with Hikvision NVRs or VMS platforms |
| Video Control and Preview | Direct video stream previews from cameras via the switch interface in supported management tools |
🧠 Additional Highlights
-
Smart PoE Management: Can auto-reboot cameras if they freeze (PoE watchdog).
-
VLAN Support: Port-based and 802.1Q VLANs for isolating traffic.
-
Bandwidth Control: Per-port rate limiting.
-
QoS: Prioritize video/audio or critical data traffic.
-
Loop Prevention: Uses STP/RSTP to avoid network loops.
-
IGMP Snooping: Efficient multicast streaming (important for IP cameras or NVR multicasting).
✅ Ideal For:
-
Medium-sized CCTV deployments (up to 16 IP cameras)
-
SMB networks needing central visual management
-
Sites with long-distance PoE runs (e.g. parking lots, perimeter security)
⚠️ Notes / Considerations:
-
Speed Limitation: 16 ports are only 10/100 Mbps, not Gigabit. Not ideal for high-bitrate cameras.
-
PoE Power Budget: 230 W ≈ 7 × 30 W devices or 15 × 15 W devices — plan camera power usage carefully.
-
Extend Mode disables Gigabit speeds — you may drop to 10 Mbps over long distances.
-
Managed Features require Hikvision software (Hik-Partner Pro, iVMS, or Hik-Central).
