Video switcher Kramer SWT3-41-U-T 4x1 USB 3.2 PoE-acceptor 10 Gbps

Kramer SWT3-41-U-T is a compact 4x1 video switcher that routes multiple USB video and audio sources to a single output. The unit supports USB 3.2 input bandwidth and PoE-acceptor functionality, enabling high-throughput connections up to 10 Gbps. Designed for conference rooms, classrooms and professional AV installations, the switcher simplifies cabling and centralizes source selection while maintaining signal integrity for high-resolution video and audio streams.

Advantages

The switcher provides four USB inputs and a single selectable output with USB 3.2 performance, supporting high-bandwidth devices such as cameras and capture cards. PoE-acceptor capability allows the unit to receive power over Ethernet, reducing the need for separate power adapters and enabling neater installations. Its compact footprint and straightforward routing controls make it easy to integrate into existing AV systems and furniture-mounted setups. The device is engineered to preserve signal quality at high transfer rates and to facilitate reliable source switching in multi-user environments.

Suitable for

• Conference rooms requiring multiple USB cameras or feeds to be switched to a single recorder or presentation system
• Classrooms and lecture halls where instructors use different USB devices (document cameras, webcams, capture devices)
• Broadcast and streaming setups needing centralized selection of high-bandwidth USB video sources
• Corporate AV installations and huddle spaces with limited rack space and simplified cabling needs

Key specifications

• Input configuration: 4 USB inputs supporting USB 3.2 bandwidth
• Output configuration: 1 selectable USB output compatible with connected host devices
• Data throughput: up to 10 Gbps for high-bandwidth video and audio
• Power: PoE-acceptor functionality for power over Ethernet support
• Form factor: compact desktop/rack-friendly enclosure suitable for AV furniture integration
• Signal types: USB video and audio passthrough with minimal signal degradation

How to use

Connect up to four USB video/audio sources to the switcher’s USB inputs and link the selectable USB output to the host device such as a PC, recorder or presentation system. If PoE is available in your network, connect an Ethernet cable to provide power to the unit; otherwise use the recommended power option from your AV provider. Use the front panel or control interface to select the active input; the device will route the chosen source to the host while maintaining USB 3.2 transfer rates. Ensure compatible drivers and host settings are configured for connected video devices to achieve expected resolution and frame rate performance.

Usage recommendations

For reliable performance, use high-quality USB 3.2-compatible cables and verify that the host device supports the intended video resolutions and bandwidth. When deploying in a PoE environment, confirm the switch or injector provides sufficient power budget. Place the unit close to the host or use shielded cabling to reduce potential interference. Regularly check firmware updates from the manufacturer to maintain interoperability and stability in multi-device setups.
