The SWIT S-4904SS is a high-performance wireless video transmission system designed for professional broadcast, film, and live production applications. Utilizing advanced WHDI (MIMO/OFDM) technology, the system delivers uncompressed 3G/HD/SD-SDI and HDMI signals with less than 1ms latency, ensuring real-time monitoring without visible delay.
With a transmission range of up to 700 meters (line-of-sight), the S-4904SS is ideal for large studio environments, outdoor productions, sports broadcasting, and multi-camera setups. It supports 2-channel embedded audio via SDI/HDMI and operates within the license-free 5.1–5.9GHz frequency band. Users can configure frequency bands as needed to optimize performance in different RF environments.
The system supports multicast functionality, allowing one transmitter to send signals to multiple receivers simultaneously. For security, AES 256-bit encryption ensures safe and protected video transmission.
Both transmitter and receiver feature V-Mount battery plates for seamless integration into professional camera and monitoring rigs. Built with an all-metal housing, the units are durable and ready for demanding production environments. The system offers true plug-and-play operation with pure hardware connection—no complex setup required.
