Swit Flow500 - 150m 3G-SDI and HDMI Video Transmitter

Swit Flow500 - 150m 3G-SDI and HDMI Video Transmitter


The Swit Flow500 is a radio-link with KUWI technology. It uses the 5.1-5.9GHz band, license free and is DFS compatible. It transmits a 3G/HD-SDI and HDMI signals up to 1080p60 up to 150m (line-of-sight) and with less than 1ms latency. The system is hardware, no configuration, plug & play, making it highly usable for directional monitoring, drones, cameras in difficult locations, steadicam, etc. Equipped with Stronger wall-cross to optimise transmission and image quality, it will keep the video transmission uninterrupted and lossless, better than traditional 5GHz systems.

Built-in scanner detects signals on all frequencies and automatically connects to the best available wireless channel. Manual selection of 7 unrestricted DFS channels is possible. Allows multi-reception from 1Tx to 4Rx. Transmitter and receivers are paired and doubly encrypted by private transmission protocol and AES128.

Wireless system based on SWIT latest KUWI wireless technology, 5.1-5.9GHz license free bands, DFS comply, supports 3G/HD-SDI and HDMI (Max 1080p60) to transmit 500 feet (150 meters) Line-of-Sight distance. The system is pure hardware connection, plug and play, which is widely used in director monitoring, drone, ropeway camera, steadicam etc. It supports 500ft/150m (Line-of-sight) reliable wireless transmission, and featured stronger wall-cross performance due to both RF optimize and image quality optimize, so that will keep video transmission without date lost or crash comparing to regular 5GHz wireless transmitters.

The FLOW wireless works under 5.1-5.9GHz, with built-in wireless scanner, and detect wireless condition of all frequencies, automatically jump to the best wireless channel to keep reliable connection and transmission, and DFS comply. You can also switch the wireless channels manually from 7 Non-DFS restricted channels. Both Tx and Rx are equipped with OLED to display signal format, wireless channel number and signal strength. Support 1 transmitter to 4 receivers reliable multicast mode. The transmitter and receivers are paired and double encrypted by private transmission protocol and by AES128, in order to protect the footages.

To ensure the quality of black level, signal noise and color reproduction of the wireless received signal, the FLOW series wireless receiving supports signal re-clock and accurate color reproduction. It provides a Micro USB port, supports OTG USB Firmware update for future more functions and the power consumtion of Tx and Rx are less than 8W. Both Tx and Rx provide NP-F DV battery plate, and 7-34V lockable DC input.
