Video switcher Kramer SWT3-41-U 4x1 USB 3.2 (10 Gbps) with Power over Ethernet

Kramer SWT3-41-U is a 4x1 USB 3.2 (10 Gbps) video switcher that combines four USB video sources into a single USB output while supporting Power over Ethernet (PoE). Designed for professional AV environments, the switcher enables reliable high-speed USB connectivity for conferencing, streaming and content sharing. The compact unit simplifies source selection and cabling by integrating USB 3.2 throughput with PoE power delivery, making it suitable for meeting rooms, lecture halls and broadcast setups where multiple USB cameras or capture devices must be managed from a single host.

Advantages

The device offers four USB inputs consolidated into one USB 3.2 (10 Gbps) output for high-bandwidth video and data transfer, reducing the need for multiple host connections. Power over Ethernet support minimizes separate power cabling and allows flexible placement within AV infrastructures. The switcher is engineered for stable signal handling and easy integration with conferencing systems, streaming appliances and recording devices. Its design focuses on straightforward source switching and consistent USB performance across connected devices.

Suitable for

• Conference rooms and huddle spaces requiring multiple camera inputs
• Live streaming setups that consolidate several USB capture devices
• Lecture halls and classrooms with multiple presenter cameras
• Broadcast and production environments needing reliable USB switching
• Hybrid meeting workflows where a single host must access multiple USB sources

Key specifications

• Inputs: 4 × USB 3.2-compatible device inputs
• Output: 1 × USB 3.2 (10 Gbps) host output
• Data transfer rate: up to 10 Gbps over USB 3.2
• Power: Power over Ethernet (PoE) support for device power delivery
• Form factor: Compact rack/desktop-friendly enclosure suitable for AV installs
• Compatibility: Works with standard USB video devices, cameras and capture hardware (host-dependent)

How to use

Connect up to four USB video sources to the switcher’s USB inputs and connect the switcher’s USB output to the host computer or streaming appliance. Provide power to the unit via a PoE-enabled network switch or injector if PoE is used; otherwise follow manufacturer guidance for alternative power options if available. Use the device’s source selection controls or the host-side software to switch between connected USB sources. Ensure the host system recognizes the selected USB device and that appropriate drivers or conferencing/streaming software settings are configured.

Usage recommendations

Place the switcher near network equipment when using PoE to minimize cable runs. Verify USB device compatibility and host USB 3.2 support to achieve the advertised 10 Gbps performance. For stable conferencing and streaming, test source switching and video formats before live events and keep firmware updated according to Kramer’s instructions.
