SwiftSync: A New 2026 Standard for 4K60 HDMI Extension—10G Performance, 1G Simplicity

In the Pro AV and IT integration landscape, finding a solution that fits every environment is a constant challenge.

If you prioritize lossless quality and zero latency, HDBaseT is often the only choice, yet it is expensive and requires high-spec cabling. Alternatively, H.264/H.265 (AVoIP) offers network flexibility and cost efficiency but often suffers from visible compression artifacts and frustrating mouse latency.

SwiftSync is a high-efficiency 1G compression technology that bridges this gap, transmitting 4K60 video over standard 1G network infrastructure while preserving original image clarity and near-zero-latency operational fluidity.

Designed for seamless deployment, it optimizes bandwidth efficiency to ensure sufficient headroom for other critical equipment, even in complex, high-traffic environments. For professional AV, IT, and industrial applications, SwiftSync is the practical solution for combining high-end transmission quality with the cost efficiency of standard 1G infrastructure.

Core Technology

1G Network Flexible Deployment

SwiftSync technology is built for versatility, allowing system integrators (SIs) to adapt to various project scales through different configurations.

Linear & Point-to-Point Deployment

• Stable & Simple: Reach beyond the distance limits of standard HDMI cables using a single CAT5e/6 or fiber cable.
• Plug-and-Play: No network switch configuration required. Ideal for straightforward long-distance transmission from a single source to one display.
• Daisy-Chaining Capability: Enabling one source to be distributed across several monitors with stable signal transmission compared to general IP-based extenders.

Scalable AV over IP Matrix

• Distributed Management: With USB KVM support, multiple operators can manage different hosts from separate locations, ideal for command centers and smart meeting rooms.
• Efficient Scalability: Scale your system by adding Transmitter (TX) or Receiver (RX) units to your existing 1G network without needing to replace central hardware.

Dual-Interface Versatility: Seamless Copper and Fiber Integration

Physical site constraints, such as narrow conduits or long distances, often dictate the cable selection. SwiftSync products such as the HKM01-4K6G feature a dual-interface design to provide maximum field flexibility.

CAT5e/6 Copper

• For transmission needs within 160 m, you can directly use standard CAT5e/6 network cables. SwiftSync’s outstanding interference resistance ensures that stable 4K60Hz image quality is maintained even in a 1G copper environment. This significantly reduces cable procurement costs and provides exceptional installation convenience in typical indoor environments, such as conference rooms and office buildings.

SFP Fiber Modules

• For distances across multiple floors or factory zones, or in environments with strong electromagnetic interference, fiber offers complete electrical isolation, protecting equipment from EMI and ground loop issues. This eliminates the risk of equipment damage caused by ground potential differences or lightning strikes, creating a robust safety barrier for high-risk or outdoor projects.

With one device supporting both interfaces, you can simplify your inventory and adapt to last-minute site changes without switching models.

SwiftSync: Why It Is the Better Choice

Professional-Grade Detail Recovery

Traditional compression often struggles with high-detail content like Excel spreadsheets or engineering drawings. SwiftSync preserves every detail; at 4K30Hz, the quality is virtually indistinguishable from uncompressed HDBaseT. Even at 4K60Hz 4:4:4, it maintains the sharp lines and color depth required for professional applications.

‍

Real-Time Operational Fluidity

Latency is the primary obstacle in remote KVM operations. While H.264/265 can introduce significant lag (80ms–150ms), SwiftSync ensures a local experience.

At 4K30Hz, it is virtually zero-latency; and at 4K60Hz, the latency is kept below 40ms (0–3 frames), enabling smooth, real-time control for scrolling, switching, and command input.

‍

Precision Motion Capturing

Handling high-dynamic images is the true challenge of video transmission.

Standard H.264/H.265 often results in motion blur, tearing, or color bleeding when displaying fast-moving subjects.

SwiftSync handles fast-moving images such as sports broadcasts or industrial monitoring, without the tearing or blurring common in other formats. It preserves the integrity of every frame, ensuring smooth transitions and visually lossless results.

• High Refresh Rate Integrity
• Dynamic Color Compensation
• Visually Lossless Optimization

Maximizing Profitability via 1G Network Infrastructure

In AVoIP planning, bandwidth requirements dictate profitability and installation risk. While 10G solutions (such as SDVoE) offer high performance, they require expensive 10G hardware and sensitive cabling.

By utilizing standard 1 Gigabit infrastructure, SwiftSync provides a significant competitive advantage for project planning:

• Lower Switch Procurement Costs
  • The per-port cost of a 10G switch is typically 3 to 5 times higher than a 1G switch. SwiftSync uses enterprise-grade 1G switches, reducing hardware costs, simplifying IGMP settings, and shortening commissioning cycles.
• Cost-Efficient Cable Reuse
  • Unlike 10G solutions that require CAT6A or CAT7 cabling, SwiftSync operates reliably on existing CAT5e/6 infrastructure, enabling seamless upgrades of existing facilities without the high labor and material costs of recabling.
• High-Level Integration
  • A single 1G link handles 4K60Hz video, USB 2.0 KVM, bidirectional audio, RS232, and IR control signals. Fewer cables mean a cleaner installation and lower long-term maintenance costs.

Reliability in Challenging Electrical Environments

In real-world engineering, system integrators (SIs) frequently encounter complex electromagnetic environments, including power-line interference, radio-frequency noise, and environmental surges.

Engineered for stability and through meticulous circuit design, SwiftSync delivers interference resistance that far exceeds traditional transmission technologies:

• Enhanced Packet Correction: Unlike uncompressed HDBaseT, which can flicker or drop signal due to minor interference, SwiftSync uses efficient encoding verification to ensure image integrity even in harsh conditions. When using HDBaseT, we recommend keeping CAT cables at least 30cm away from power lines.
• High-Tolerance Physical Design: SwiftSync products feature reinforced ESD and surge protection, ensuring 4K signal purity in factory automation lines or server rooms with high-power equipment.
• Fiber Isolation Advantage: For high-risk or outdoor projects, the fiber interface provides complete electrical isolation, eliminating ground loop issues.

Why Professional SIs are Switching to SwiftSync

In actual engineering cases, SwiftSync solves the most critical pain points:

• Versatile Applications: Dedicated solutions for both one-to-one and many-to-many setups.
• High Environmental Tolerance: More resilient to cable quality and EMI than HDBaseT or SDVoE.
• Cost-Benefit Leadership: High-end quality delivered within a 1G standard network budget.
• All-in-One Integration: Built-in KVM and independent audio enable a single device to manage all peripherals.
