Introduction to the DS-3E0310HP-E and its key features
The DS-3E0310HP-E 8-Port 10/100 PoE Switch is a purpose-built, unmanaged Layer‑2 switch designed for compact surveillance and edge IoT deployments. With eight 10/100 Mbps PoE downlink ports (including a single Hi‑PoE/802.3bt capable port), two gigabit uplinks, a 110 W total PoE budget and a rugged fan‑less metal enclosure, this switch targets installers and integrators who need a low‑management, reliable power-over-Ethernet solution.
Key features at a glance:
- 8× 10/100 PoE downlink ports— Port 1 supports Hi‑PoE (802.3bt); Ports 2–8 support 802.3af/at.
- 2× Gigabit uplinks— 10/100/1000 Mbps RJ45 ports for upstream network connectivity.
- 110 W PoE budget— Enough to power multiple cameras, access points or IoT devices.
- Long‑range “Extend” mode— Support for longer cable runs (approx. 250–300 m) when needed.
- Rugged, low-noise design— Fan‑less metal chassis with built‑in surge protection, wall or desk mountable.
Detailed description of specifications and benefits
The DS-3E0310HP-E offers 8 downlink ports operating at 10/100 Mbps, with Port 1 designated as a Hi‑PoE port compliant with 802.3bt (region dependent power rating). Ports 2–8 support IEEE 802.3af/at delivering up to 30 W per port. The total PoE budget is 110 W, which lets you mix standard PoE cameras and one high‑power device such as a PTZ camera, an all‑in‑one access point, or other 802.3bt‑compatible devices.
Benefits:
- Single high‑power port allows connection of a demanding device without the need for a separate injector or midspan.
- Seven additional PoE ports provide flexible power distribution for typical CCTV/IoT devices.
- End‑span and mid‑span compatibility broadens support across device types and deployments.
Two gigabit RJ45 uplink ports provide high‑speed aggregation to the core network or NVR. While the downlinks are 10/100 Mbps, the uplinks allow for efficient backhaul of multiple camera streams or aggregated IoT data. The switch offers an approximate switching capacity of 5.6 Gbps and a forwarding rate around 4.17 Mpps, plus internal buffering in the megabit range and a typical MAC table sufficient for small to medium edge deployments.
Benefits:
- Gigabit uplinks reduce the chance of upstream bottlenecks even when several cameras are in use.
- Appropriate switching capacity for typical 10/100 PoE device mixes used in surveillance.
One standout feature is the Extend mode, which extends PoE delivery to approximately 250–300 m over quality cabling. Note that when in Extend mode, link speed may drop to 10 Mbps and throughput characteristics change, so it’s best used for single camera feeds or low‑bandwidth sensors rather than high‑resolution multi‑stream video.
Benefits:
- Enables deployments where running switches closer to devices is not practical.
- Reduces the need for local power at the device location.
The switch is powered by a 48 V DC input (2.5 A nominal) and consumes up to approximately 120 W at maximum load. Its fan‑less metal housing supports wall or desk mounting and is rated for typical indoor operating temperatures of 0 °C to 40 °C. Built‑in surge protection (around 6 kV) adds extra resilience when installed in locations prone to transient events.
Benefits:
- Fan‑less design means silent operation — ideal for offices, retail and indoor camera closets.
- Metal chassis gives improved durability for field or rack‑adjacent installations.
- Surge protection increases survivability in areas with electrical transients.
Use cases and scenarios where this switch excels
The DS-3E0310HP-E is tailored for installers, system integrators and small site operators who need a practical, no‑nonsense PoE switch. Typical deployments include:
- Small to medium CCTV systems:Power multiple fixed cameras and one PTZ or high‑power camera on the Hi‑PoE port while sending streams to an NVR or server via gigabit uplinks.
- Retail and branch offices:Connect IP phones, access points and cameras without the complexity of managed switches.
- Access control and door systems:Power an electronic strike or controller from the Hi‑PoE port while serving door sensors and readers on standard PoE ports.
- Edge IoT installations:Sensors, small controllers and environmental monitoring devices can be powered from the same compact switch at the network edge.
- Long‑reach camera placements:Use Extend mode for out‑of‑the‑way cameras where running fiber or additional power outlets is not desirable.
In each of these scenarios the switch’s simplicity — unmanaged operation, durable build and power flexibility — speeds installation and reduces ongoing maintenance needs.
Comparisons with similar products on the market
When evaluating PoE switches, buyers generally balance port speeds, PoE budget, management features and cost. The DS-3E0310HP-E positions itself as a budget‑friendly, high‑power option but with specific tradeoffs:
- Versus fully managed Gigabit PoE switches:Managed gigabit switches (24-port or 8-port variants) provide VLANs, QoS, ACLs and SNMP — useful for complex networks. The DS-3E0310HP-E is unmanaged and focuses on plug‑and‑play simplicity, making it cheaper and easier to deploy where advanced features are unnecessary.
- Versus 8‑port gigabit PoE switches:Some competitors offer gigabit on every downlink port. Those models deliver higher per‑port throughput for multi‑megabit camera streams but often come at a higher price and higher power draw. The DS-3E0310HP-E trades per‑port speed for affordability and includes the critical Hi‑PoE capability many budget switches lack.
- Versus midspan injectors and separate Hi‑PoE injectors:Using a single integrated switch with a Hi‑PoE port simplifies wiring and reduces equipment footprint compared with separate injectors or midspans. It’s more space‑efficient and typically easier to manage for small installs.
- Versus similar unmanaged PoE models:Compared with other unmanaged PoE switches with similar budgets, the inclusion of a Hi‑PoE port and extend mode sets the DS-3E0310HP-E apart for installers who need either a single high‑power feed or extended cabling reach without changing product families.
Bottom line: If you need enterprise management, per‑port gigabit speeds and advanced monitoring, a managed gigabit switch is more appropriate. If you need cost‑effective PoE power with a high‑power port and long‑reach capability for cameras or access control, the DS-3E0310HP-E is a strong candidate.
Customer feedback and practical install notes
Official public user reviews for specific model numbers may be limited; however, feedback from installers and integrators using similar switches highlights consistent themes:
- Installers appreciate the convenience of a single Hi‑PoE port for powering PTZ cameras or high‑power access points without a separate power injector.
- Field teams commonly praise the fan‑less metal design for its quiet operation and physical reliability in small equipment closets.
- Users advise confirming regional Hi‑PoE power ratings and checking camera power requirements before deployment — Hi‑PoE power allocation can vary by region and regulation.
- When using Extend mode, installers recommend testing actual throughput and video quality over the intended cable run because speeds can drop to 10 Mbps and affect high‑resolution streams.
If you’re considering this switch, ask your reseller for datasheets relevant to your region and confirm warranty/approval details. Also check cable quality and routing to make sure long runs meet expectations.
Conclusion: Why the DS-3E0310HP-E is a great choice
The DS-3E0310HP-E 8‑Port 10/100 PoE Switch strikes a practical balance between power, durability and cost. Its defining strengths are the single Hi‑PoE/802.3bt port combined with seven standard PoE ports and a 110 W total budget, making it particularly well suited to CCTV, small branch and edge IoT scenarios where one high‑power device and several standard devices must be supported from a compact, low‑maintenance unit.
For customers who prioritize plug‑and‑play simplicity, silent operation, surge protection and the ability to reach longer cable distances without additional power infrastructure, this switch offers a compelling value proposition. While it is not aimed at environments requiring full management features or per‑port gigabit performance across all ports, its mix of Hi‑PoE capability, gigabit uplinks and a rugged design make it a smart choice for many installer and small‑site use cases.
In short, choose the DS-3E0310HP-E if you need a dependable, budget‑minded PoE switch with one high‑power port, flexible deployment options and minimal configuration overhead — especially where camera power and simple, reliable edge networking are the priorities.
