How to add wireless capability to any HDMI video monitor ? (Sony FX6 + Atomos)
What’s in the Wireless Transmission Kit?
Inside you’ll find:
- 1 × HDMI transmitter module that look like a simple cable and plug to USB for power.
- 1 × HDMI receiver module with similar look to the transmitter
- 1 × Micro‑HDMI to HDMI adapter
- 1 × Mini‑HDMI to HDMI adapter
- 1 × One documentation in english
Both HDMI adapters can be mounted on either the transmitter or receiver.
The lightweight pouch keeps everything organized and is far more convenient than a bulky 5 m HDMI cable in your camera bag.
How the wireless kit works.
This is a wireless system that plugs into an HDMI port and has the transmitter and receiver integrated into the port. The remaining wire is a USB cable that provides power.
It’s easy to install and works without any configuration.
The signal is in Full HD.
One port is the transmitter, labeled TX.
The other is the receiver, labeled RX. But the external appearance is very similar.
What’s interesting is that the transmission part is integrated directly into the port, making it virtually invisible.

How to Connect the Kit ?
Although the documentation is only in English, setup is truly plug‑and‑play—there are no buttons or menus to configure.
I created this video to show the basic setup and test of this great device.
- Connect the RX (receiver) HDMI port to your TV or monitor.
- Connect the TX (transmitter) HDMI port to your camera or computer.
- Power on either unit first—you can start with the receiver or transmitter.
Status messages appear on‑screen automatically. If you swap TX/RX by mistake, you’ll simply see no image—no harm done.
I plugged the RX to the Sony compatible battery that have an USB extra output.
The TX is plugged as well to an IDX battery that also have a USB port.
Operation & Transmission Delays
After powering up, the receiver requires about 28 seconds before the live image appears. Once active, latency is around 20 ms (≈8 frames at 25 fps), versus ≈10 ms for a standard HDMI cable. The transmitter module itself only needs 6 seconds to re‑sync after HDMI disconnection.
These timing are with the wireless transmitter.
And these with a simple HDMI cable.
Be aware that powering the USB port on these batteries is done by an action on the rear button. Sometime it’s just a press, sometime, you need a long press depending on the brand.
Maximum Transmitter Range
In my reinforced‑concrete environment, I achieved a reliable 5 m range. In clear line‑of‑sight, the kit performs up to 10 m—ideal for multi‑room playback or remote video monitoring. With a Bluetooth keyboard/mouse, you can even control your source device from another room. For a video shooting, it’s clearly better than a 5m hdmi cable that will give you only 3 m usable with the risk of being damaged by people walking on it.
Power Consumption
Both modules draw power via USB from your camera or monitor battery packs:
- Receiver: ~3 W
- Transmitter: <1 W
This low power draw makes it easy for any assistant to set up—simply press the battery’s USB output button to start.
Just don’t forget to unplug them because there is no way to turn it off, so it may just drain the battery if you forget them.
To get these number I used a simple USB measure dongle as you can buy from here.
Drawbacks of the Wireless HDMI Kit
- Heat Build‑Up: After 10 minutes of continuous use, the plugs can reach ~50 °C. Avoid poorly ventilated or outdoor setups in direct sun.
You can check these picture taken after 10mn of transmission.
I used this camera module to create such view. - USB Power Dependency: Requires a free USB port on your device battery. You may need to upgrade or add a USB module. Remember to unplug after use to prevent battery drain—there’s no power‑on LED.
Conclusion
I’m thoroughly impressed by the ease of setup, image quality, and versatility of this Wireless HDMI Transmission Kit. It’s an affordable upgrade compared to rewiring or investing in new gear. Perfect for sending a clean feed to a client monitor without cables—highly recommended!
One the FX6, it’s just an extra cable without the need of any extra support. For the monitor, it’s also very small footprint.
