The FEELWORLD WT1S is more than just a wireless video transmitter—it’s your on-set communication hub and live streaming powerhouse. Designed for filmmakers, camera crews, and content creators, it combines 4K wireless video transmission, full-duplex intercom, and direct streaming capabilities into one compact system. Operating on the 5.1–5.9GHz frequency with OFDM modulation, the WT1S supports 13 frequency channels and features smart channel scan to automatically select the clearest channel, ensuring reliable signal in crowded environments. Preset grouping allows automatic linking between transmitter and receiver when set to the same group—no manual pairing required, and OLED displays on both units show signal strength, battery level, group, and resolution at a glance. The transmitter features 1x SDI input and 1x HDMI input/output, while the receiver provides 1x SDI output and 2x HDMI outputs, supporting one transmitter to four receivers for multi-camera productions. Built-in full-duplex intercom enables real-time two-way communication between director and camera operator without the need for separate walkie-talkies, streamlining on-set coordination. For live streaming, use the included Type-C to Ethernet adapter to connect the receiver directly to your network and stream RTSP video feed to OBS, VLC, or YouTube without a capture card. Both transmitter and receiver support NP-F batteries and DC 6–16V power adapters, and the receiver also supports USB-C (5V/1.5A) power input for use with power banks. The compact 138.8g body features a 1/4″ screw thread for mounting on cameras, gimbals, or light stands. Purchase two WT1S sets to switch one receiver to transmitter mode, easily creating a dual-camera or multi-camera wireless video system. Package includes: 1x Transmitter, 1x Receiver, 5x Antennas, 1x Cold Shoe, 1x USB-A to USB-C Adapter, 1x Type-C to Ethernet Adapter, 1x User Manual. Every WT1S unit is backed by a 1-year limited warranty against manufacturing defects—contact us via Amazon Buyer-Seller Messaging for support.
