Hanwha SKY-SW28G-001 26-Port PoE+ Managed Switch

Hanwha SKY-SW28G-001 26-Port PoE+ Managed Switch

The SKY-SW28G-001 is a 26-port managed PoE+ gigabit network switch purpose-built for multi-camera surveillance deployments. It combines centralized power delivery, non-blocking switching fabric, and dual uplink redundancy—features that eliminate common bottlenecks in enterprise video networks where camera count, bandwidth demand, and uptime requirements are non-negotiable.

Overview

This switch addresses a real problem: powering and switching 15–24 IP cameras without adding external midspan injectors, overloading your PoE budget, or introducing single points of failure. The SKY-SW28G-001 handles the power and bandwidth requirements of modern surveillance in a single 1U rack footprint, reducing cable runs, complexity, and failure modes. It integrates natively with Hanwha Wisenet SKY Cloud VMS, streamlining camera provisioning and network management across distributed sites.

Key Features

• 24 PoE+ Ports at 30W Each, 370W Total Budget — Standard 802.3at PoE+ delivers 30W per port, enough to power 4K, thermal, and multi-sensor cameras without compromise. The 370W aggregate budget means you can run all 24 ports at maximum draw simultaneously—no rotating priority schemes, no disabled ports. If you have 18 cameras averaging 25W and 6 thermal units at 28W, they all operate at full capacity without contention. This eliminates the hidden cost of supplemental power supplies or midspan injectors.
• 56 Gbps Non-Blocking Switching Fabric — All 26 ports share a dedicated 56 Gbps backplane with no bandwidth oversubscription. In practical terms: 24 cameras each pushing 8 Mbps of video plus metadata all transit simultaneously without stuttering, frame loss, or congestion. This matters in retail, campus, and warehouse deployments where live video and forensic playback must coexist without competing for bandwidth.
• Dual Uplink Configuration (2x RJ-45 Gigabit + 2x SFP) — Two standard 1 GbE RJ-45 uplinks plus two SFP gigabit uplinks provide both immediate connectivity and future-proofing. In redundant topologies, uplink failure doesn't take down video flow—traffic automatically reroutes to the surviving path. For large facilities with zone-based switching, the SFP uplinks enable fiber backbone connections, eliminating Ethernet distance limits and noise in noisy industrial or warehouse environments.
• 802.3af and 802.3at Backward Compatibility — Automatically detects legacy 802.3af devices (15.4W max) and newer 802.3at hardware (30W) in the same network. Mixed environments—where older fixed cameras and new motorized or panoramic units coexist—operate without manual port configuration or device restrictions. The switch adapts to each device's power class automatically.
• Rack and Wall Mounting — Fits standard 19-inch racks and mounts directly to walls in distributed facilities. No separate enclosure or mounting bracket required. This flexibility is critical when your switch location is a small server room (rack) versus a closet in a remote warehouse (wall mount).
• Operating Temperature Range 0°C to 50°C (32°F to 122°F) — Rated for climate-controlled indoor spaces. This range covers standard server rooms and facility closets but excludes outdoor cabinets, unheated garages, or direct sunlight exposure. If your deployment includes outdoor or extreme-temperature enclosures, you'll need supplemental cooling or an industrial variant.

Integration and Compatibility

Native Wisenet SKY Cloud VMS integration means camera discovery, provisioning, and remote management flow directly from your VMS without manual IP assignment or DHCP relay configuration. The switch is ONVIF-compliant, supporting any ONVIF-Profile-S IP camera or edge device—not locked to Hanwha hardware. This matters if you're running a mixed-vendor environment or plan to swap cameras without swapping the switch.

In distributed deployments, the dual uplink architecture supports active-active or active-passive failover. Redundancy is enforced at the network layer, not the power layer—if your switch fails, your cameras lose PoE. For mission-critical installations requiring power isolation, consider dual switches with independent power feeds feeding separate camera groups.

Deployment Scenarios

This switch is purpose-built for 15–24 camera installations in retail chains, corporate offices, manufacturing floors, and university campuses where centralized PoE simplifies infrastructure and reduces operational overhead. Large facilities benefit from cascaded switch topologies—each zone gets its own SKY-SW28G-001, all connected via the dual uplinks to a core switch or router. Enterprise buyers already standardized on Hanwha surveillance hardware gain faster integration and lifecycle management through native Wisenet SKY integration.

Frequently Asked Questions

Q: Can I power 24 full-draw cameras (30W each) simultaneously on the SKY-SW28G-001?

A: Yes. The 370W total power budget supports all 24 PoE+ ports at 30W each. Unlike budget switches with oversubscribed power pools, the SKY-SW28G-001 is sized for full-port deployment without port disabling or power contention.

Q: Does the SKY-SW28G-001 support older 802.3af (15.4W) cameras?

A: Yes. It automatically detects and supplies appropriate power to both 802.3at (PoE+, 30W) and legacy 802.3af (PoE, 15.4W) devices. Mixed-generation camera networks operate without manual configuration.

Q: What happens if one uplink fails in a redundant setup?

A: Network traffic reroutes to the surviving uplink. However, PoE power is supplied locally by the switch itself—uplink failure doesn't affect powered devices. Loss of the switch means loss of power and switching for all downstream cameras.

Q: Is the SKY-SW28G-001 suitable for outdoor cabinet deployment?

A: No. The 0–50°C operating temperature range is rated for climate-controlled indoor spaces only. Outdoor cabinets, unheated storage, or direct sunlight exposure require supplemental cooling or an industrial-rated switch variant.

Q: Does the SKY-SW28G-001 require special configuration to work with non-Hanwha cameras?

A: No. It is ONVIF-compliant and works with any standard ONVIF-Profile-S IP camera. Wisenet SKY integration is optimized for Hanwha hardware but not required. The switch is vendor-neutral at the network layer.

Q: What is the switching fabric capacity?

A: 56 Gbps non-blocking fabric. All 26 ports can operate at gigabit speeds simultaneously without oversubscription, eliminating bandwidth bottlenecks in multi-camera networks.

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

The SKY-SW28G-001 solves a specific infrastructure problem: feeding power and gigabit bandwidth to 20+ concurrent cameras without cascading external injectors or undersizing your switching capacity. I've seen too many deployments where a budget switch with "370W" is actually 370W shared across oversubscribed backplane, forcing engineers to disable ports or add complexity. This one doesn't have that trap.

Technical Highlights:

• 56 Gbps non-blocking fabric with 24 gigabit ports: No bandwidth oversubscription. A typical 4K camera at 8–12 Mbps plus metadata doesn't compete with other cameras for trunk bandwidth. This matters in live video playback scenarios where forensic review and real-time monitoring coexist.
• 370W power budget at 30W per port: Full-draw deployment is standard, not an edge case. Thermal cameras, 4K modules, and multi-sensor units run at rated wattage across all 24 ports simultaneously. No power-trading between ports.
• Dual RJ-45 + dual SFP uplinks: Redundancy isn't theoretical. In a zone-based architecture, if one uplink fails, the second carries traffic. SFP sockets enable fiber backhaul, crucial in noisy industrial or warehouse settings where 100m+ Ethernet runs attract EMI.

Deployment Considerations:

• The 0–50°C operating range excludes outdoor or unheated enclosures. If your switch lives in a shipping dock or outdoor equipment cabinet, you need active cooling or an industrial variant.
• Wisenet SKY VMS integration is native but optional—ONVIF compliance means mixed-vendor networks work, though you lose single-pane VMS provisioning with non-Hanwha cameras. Plan for that if you're blending brands.
• Uplink redundancy handles network failure, but the switch itself is a single power point. For mission-critical sites, consider dual switches with independent PoE power feeds to isolate power domain failures.

The SKY-SW28G-001 is the right choice for retail chains, corporate campuses, and manufacturing floors deploying 18–24 cameras in a single zone. It removes the hidden cost of midspan injectors and the guesswork of power budgeting. If you're standardized on Hanwha, the Wisenet SKY integration accelerates deployment. If you're running mixed brands, the ONVIF compliance keeps your options open.
