Hanwha SKY-SW20G-001 18-Port PoE+ Managed Network Switch

Hanwha SKY-SW20G-001 18-Port PoE+ Managed Network Switch

The Hanwha SKY-SW20G-001 is a managed gigabit network switch purpose-built for IP surveillance deployments. With 16 PoE+ ports delivering up to 30W each (802.3at) and a 250W total power budget, this switch eliminates the need for external power injectors when deploying multiple high-power cameras across mid-to-large installations. The 40 Gbps non-blocking switching fabric prevents the common bottleneck in consumer-grade switches when simultaneous 4K streams from 15+ cameras converge on recording servers or display stations. The SKY-SW20G-001 integrates natively with Wisenet SKY VMS, automating VLAN management and QoS prioritization for surveillance workloads without third-party configuration overhead.

Key Features

• 16 PoE+ Ports, 2 Gigabit Uplinks: Delivers up to 30W per port to high-power cameras, or 15.4W for standard PoE devices. The 250W total power budget supports 8+ maximum-draw cameras simultaneously—eliminating the cost and rack clutter of separate power supplies or midspan injectors. This direct power delivery reduces installation time by hours on jobs with 10+ cameras.
• Dual Uplink Architecture (RJ-45 + SFP): Two copper gigabit uplink ports plus two SFP fiber slots enable mixed-media trunk connections. Fiber uplinks are essential for runs beyond 100 meters where copper degradation becomes visible; copper uplinks integrate directly into standard data center switching without additional transceivers. This flexibility lets you build a migration path: deploy copper today and add fiber trunks later without replacing the switch.
• 40 Gbps Non-Blocking Switching Fabric: Full-line-rate switching across all ports prevents congestion—a critical distinction from budget switches that advertise total backplane bandwidth but enforce practical per-port caps. This architecture handles sustained multi-4K streams without frame loss or latency spikes during network events (alerts, bandwidth-hungry analytics, VMS backups). When 12 cameras stream 4K @ 30fps simultaneously to an NVR, packet loss simply does not occur.
• Managed Switch Capabilities: Native VLAN tagging, QoS per port, and loop detection reduce misconfiguration risk in complex deployments. Security integrators can isolate camera traffic from office IT networks and prioritize recording traffic over maintenance tasks without proprietary software. This means faster commissioning and easier troubleshooting on multi-tenant or hybrid-use sites.
• Rack and Wall Mounting: Flexible form factor accommodates both telecom-style equipment racks and wall-mounted installations in constrained spaces (warehouse offices, retail back rooms, modular shelters). No dedicated rack space? Mount it on the wall adjacent to your main switch closet.
• Gigabit Port Speed (All Ports): All 18 PoE ports operate at full 1000 Mbps—not the 10/100 limitations common in budget PoE switches. This eliminates negotiation delays and guarantees consistent throughput for 4K and multi-megapixel camera streams at 30+ fps. No hidden throughput surprises during peak recording.
• Wisenet SKY VMS Integration: Native compatibility with Hanwha's cloud-based VMS platform ensures switch-level features (VLAN, QoS, bandwidth reservation) align automatically with recording and analytics priorities. This reduces manual tuning and post-deployment troubleshooting. If you're running Hanwha IP cameras with Wisenet SKY, the switch learns your topology and optimizes traffic flow without additional configuration overhead.
• Operating Temperature 0–50°C (32–122°F): Supports most indoor and climate-controlled outdoor deployments. Temperature-hardened enclosures are recommended for unheated warehouses, external cable vaults, or locations subject to seasonal freeze-thaw cycles.

Integration & Compatibility

The SKY-SW20G-001 (often searched as SKY SW20G 001) is designed to work seamlessly with the full Hanwha IP camera line and integrates directly with Wisenet SKY VMS. VLAN and QoS settings can be provisioned through the VMS dashboard, reducing the need for separate network management tools. For installations mixing Hanwha and third-party cameras, the switch operates as a standard managed switch supporting 802.1Q VLAN tagging and SNMP management, making it compatible with any ONVIF-compliant network video recorder or VMS platform.

When to Choose a Different Model

If you need more than 16 PoE+ ports or your installation requires fiber-only uplinks from the start, evaluate higher-port-count models in the Hanwha switch family. If your deployment is purely indoor with a small camera count (under 6 cameras) and no need for managed VLAN isolation, a budget unmanaged PoE switch may suffice—but be aware you sacrifice congestion protection and isolation capabilities. For unheated outdoor cable vaults or sites subject to extreme temperature swings, consult an environmental review before deploying in the 0–50°C window.

Frequently Asked Questions

Q: Can I use the SKY-SW20G-001 with non-Hanwha cameras?

A: Yes. The switch is a standard managed gigabit PoE+ device compatible with any ONVIF-compliant IP camera and NVR. Wisenet SKY integration is optional—you can configure VLANs and QoS manually for third-party devices.

Q: What is the maximum power draw per port?

A: 30W per port (802.3at PoE+). High-draw cameras (dome PTZs, certain thermal models) that exceed 30W will require a separate power supply or a higher-wattage power supply fed to a different switch port.

Q: Can I replace a failed SKY-SW20G-001 with a standard enterprise switch?

A: Technically yes, but you lose the native Wisenet SKY integration and surveillance-optimized QoS defaults. For best results in a Hanwha deployment, stick with the SKY-SW20G-001 or consult Hanwha for approved alternatives.

Q: Is the SKY-SW20G-001 rack-mountable?

A: Yes. The switch supports both 19-inch rack mounting (with rail kits) and wall mounting. Confirm your physical space before ordering.

Q: What is the switching fabric capacity?

A: 40 Gbps non-blocking. This means all 18 ports can operate at line rate simultaneously without internal congestion, critical for multi-4K surveillance deployments.

Q: Does the SKY-SW20G-001 support fiber uplinks?

A: Yes. Two SFP Gigabit fiber slots allow long-distance trunks (1000Base-SX or 1000Base-LX) to remote NVRs or access points without copper degradation beyond 100 meters.

Perspective based on aggregated IP Security Depot and affiliated engineering team experience.

The SKY-SW20G-001 is surveillance infrastructure built with real constraints in mind. That 250W PoE budget translates directly to labor savings and cable simplicity on large installs—no need to run parallel power distribution or coordinate midspan injectors across a warehouse or retail location. The 40 Gbps non-blocking fabric is the differentiator: most budget managed switches throttle per-port throughput when all ports are active. The SKY-SW20G-001 does not. If you're deploying 12+ 4K cameras, this matters.

Technical Highlights:

• 250W PoE Budget @ 30W per Port: Supports 8 simultaneous maximum-draw cameras without external power supplies. Reduces rack clutter and eliminates the labor cost of parallel distribution runs—easily saves 4–6 hours on mid-size jobs.
• 40 Gbps Non-Blocking Switching Fabric: All 18 ports can stream at full gigabit simultaneously. Consumer-grade managed switches often advertise high backplane numbers but enforce per-port caps. Not here. This is why you don't see frame drops during simultaneous analytics offload, VMS backup, and live viewing.
• Dual Uplink Flexibility (RJ-45 + SFP): Two copper gigabit ports plus two SFP fiber slots. Deploy copper today; migrate to fiber later if runs exceed 100 meters. No rip-and-replace required. This future-proofs your infrastructure investment.

Deployment Considerations:

• Operating Temperature 0–50°C: Handles most climate-controlled indoor and sheltered outdoor spaces. Unheated warehouses or external vaults in freeze zones need supplemental enclosures—plan for that in site surveys.
• Wisenet SKY VMS Dependency: The 'native integration' is real, but if you're running a third-party VMS (Milestone, Genetec, Pelco), you configure VLANs and QoS manually. Not a blocker, but know the difference: Wisenet SKY users get automatic topology learning; others do not.
• Power Budget Math: 250W total means if you're running eight 30W cameras, you've consumed the budget. A ninth camera at 25W will fail negotiation or reboot. Plan your power draw per port before you deploy.

The SKY-SW20G-001 is the right choice for mid-to-large surveillance builds (12–16 cameras) where you need reliable, non-blocking gigabit switching, integrated PoE to eliminate external power distribution, and surveillance-specific QoS tuning. If you're building a Hanwha ecosystem, it eliminates a significant integration headache. If you're mixing vendors, it still works, but you lose the automation benefits. For smaller deployments (4–6 cameras) or budget-constrained projects, a simpler unmanaged PoE switch may suffice—but you sacrifice congestion protection.
