Why Choose the DS-3E0520HP-E
Choose the Hikvision DS-3E0520HP-E when a surveillance system requires Gigabit performance, higher PoE output and simple plug-and-play deployment without managed-switch configuration. Its four Hi-PoE ports support demanding devices, while the remaining twelve PoE ports suit standard cameras and network endpoints. Dual RJ45 and dual SFP uplinks provide more backbone flexibility than a basic 18-port switch, and the 40Gbps switching capacity supports full-speed data forwarding across the system. Security Wholesalers supplies this switch for professionally designed Hikvision and standards-compatible IP surveillance networks.
Buyer Decision Tips
Port Clarification: The DS-3E0520HP-E has 20 physical network ports in total: 16 PoE access ports, two Gigabit RJ45 uplinks and two Gigabit SFP fibre ports.
Power Planning Tip: Add the maximum wattage of all connected devices and keep the combined requirement within the switch’s 225W PoE budget.
Fibre Note: SFP transceiver modules and fibre cabling are not built into the ports and must be selected separately to match the required fibre type, connector and distance.

Choosing the Right Model
- Choose this model if: You need 16 Gigabit PoE ports, four 90W Hi-PoE ports, a 225W power budget and both copper and fibre uplinks.
- Choose a lower-power switch if: All connected devices use standard PoE and their combined load is well below 225W.
- Choose a managed switch if: The project requires VLAN configuration, spanning tree, link aggregation, traffic prioritisation or remote port management.
- Use long-range mode carefully: Extended-distance operation may reduce port speed and should use suitable high-quality cabling.
- Check rack depth and ventilation: Allow adequate space for the 220.8mm-deep chassis, rear power connection and airflow.
FAQs
- How many PoE devices can the DS-3E0520HP-E power?
The switch provides 16 Gigabit PoE access ports, allowing up to 16 compatible devices to be connected. The total combined load must remain within the 225W PoE power budget. - How many uplink ports does the switch have?
It has four dedicated Gigabit uplink interfaces: two RJ45 copper ports and two SFP fibre ports. The product therefore has 20 network ports in total. - Which ports support 90W Hi-PoE?
Ports 1 to 4 support IEEE 802.3bt Hi-PoE output up to 90W per compatible port. Actual available power is also limited by the shared 225W switch budget. - What does the PoE watchdog function do?
The watchdog checks whether a connected PoE camera is responding. When an eligible device becomes unresponsive, the switch can restart power to that port to help restore the camera automatically. - Can the switch transmit data and power over 300m?
Yes, supported ports can operate over distances up to 300m in long-range mode with appropriate cabling and connected equipment. Extended mode may operate at a reduced network speed compared with standard Gigabit mode. - Are SFP fibre modules included?
No. Compatible SFP transceiver modules and fibre cables must be selected separately according to the fibre type, connector, wavelength and required transmission distance. - Does the DS-3E0520HP-E require configuration?
No. It is an unmanaged switch designed for plug-and-play installation. Its long-range, isolation and watchdog functions are selected through hardware controls rather than a web-management interface. - What should I check before purchasing this switch?
Confirm the number of devices, individual power requirements, total PoE load, uplink type, cable distances, rack space and whether managed networking features are required. Security Wholesalers can supply this switch for compatible professional IP surveillance systems.
