KUWI Wireless Technology

SDI&HDMI 500ft / 150m (LOS)

FLOW500 wireless system is 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.

150 meters Transmission

Strong Wall-cross Performance

FLOW500 wireless 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.
* Supports SDI & HDMI embedded audio (CH1&2) transmission.

OLED Display & Channel Switch

DFS comply

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.


Multicast and Double Encryption

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.




Reclock & Color Reproduction


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.




USB Firmware Update

The FLOW series wireless provides a Micro USB port, supports OTG USB Firmware update for future more functions.






Power Supply

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.


FLOW500 standard package includes:

1x Transmitter
1x Receiver
1x Articulating arm trestle (Cold shoe and 1/4”)
1x D-tap to pole-tap DC cable
1x AC-DC power adaptor
1x Carrying case (for everything)


FLOW500 1T2R Kit includes:

1x Transmitter
2x Receivers
1x Articulating arm trestle (Cold shoe and 1/4”)
2x D-tap to pole-tap DC cable
2x AC-DC adaptor
1x Carrying case (for everything)

Pair the Transmitter and Receiver

The FLOW wireless Tx and Rx are already paired in factory. You can directly use.
But if you have several units and mixed up the Tx and Rx, or if you need to do multi-cast, you need to re-pair by yourself. Pairing steps:

1 Tx to 1 Rx
(1) Power on the Tx and connect SDI or HDMI source to Tx.
(2) Power on the Rx and connect with a monitor.
(3) Pull the Rx joystick right to “CONF/PAIR” page, and make sure the CONF is “HOST” mode*. Pull the joystick down to select “PAIR” – “YES” and press the joystick to confirm.
(4) Pull the Tx joystick right to “PAIR” page, and pull down to select “YES”, and press the joystick to confirm.
(5) Then the “Link” indicators of both Tx and Rx are blinking, and when they stopped blinking, pairing succeed and the Rx outputs video.
* If the Rx is “SLAV” mode, please change to “HOST” mode and restart the Rx to apply.

1 Tx to Multi Rx
(1) Successfully pair a Tx with an Rx first, and keep them powered on.
(2) Power a new Rx on, and pull the Rx joystick right to “CONF/PAIR” page, and change the CONF to “SLAV” mode, and restart the Rx.
(3) Pull the Rx joystick right to “CONF/PAIR” page again, and pull joystick down to select “PAIR” – “YES”, and press the joystick to confirm.
(4) Pull the Tx joystick right to “PAIR” page, and pull down to select “YES”, and press the joystick to confirm.
(5) Then the “Link” indicators of both Tx and new Rx are blinking, and when they stopped blinking, pairing succeed and the new Rx outputs video simultaneously.
(6) Set more Rx to “SLAV” mode and pair them together by above steps.

How to Get the Best Effect of Wireless Transmission

(1) Set the Transmitter and Receiver antennas straight up, even if they are laid down installed.
(2) Set the Receiver as high as possible.
(3) Avoid walls, trees, water and any blockage as best as you can.
