Supported formats: 1080p from 23.98 up to 60 fps (23.98/24/25/29.97/30/50/59.94/60), 1080psf 23.98/24, 1080i 50/59.94/60 and 720p 50/59.94/60. A European 25p corporate film and a 59.94i broadcast job run through the same kit.

Around 32 ms of delay is less than two frames at 50p. A director calling shots from a tent behind the stage, or a vision mixer cutting a wireless angle against cabled cameras, works with it as a live picture. It is also short enough for feeding LED screens beside a stage.

The first two embedded audio tracks, from SDI or HDMI alike, are carried across too – a camera-mic reference for the edit, or a programme mix sent along for monitoring.

On the radio side, a built-in scanner checks every frequency, moves the link to the best channel by itself and keeps operation DFS-compliant, which European rules demand on part of the 5 GHz range. Crews who plan frequencies by hand can pick from seven non-DFS channels instead. According to SWIT, RF and image-processing tuning gives the FLOW2000 better wall-crossing than typical 5 GHz links, and the company names stadiums, concerts and busy public spaces full of phones and Wi-Fi routers as places where the connection holds.

Before passing the picture on, each receiver re-clocks it and reproduces colour faithfully, with black level and noise held in check. That pays off where the picture is judged closely: on a grading monitor at the DIT cart, or as a source on the programme bus of a switcher.

Every link is locked twice: the radio protocol itself belongs to SWIT, and the content is AES-128 encrypted on top of it – SWIT calls this double encryption. Units have to be paired before they exchange a picture, so at a private celebrity event or a confidential internal broadcast, an outside receiver stays blank.

All three units carry a 0.96-inch OLED showing signal format, channel and signal strength, operated with a five-way button. Setup is hardware-only – no app, no laptop, nothing to install. Firmware updates load through the micro-USB port.

Each unit draws no more than 8 W. Power comes from Sony L-series (NP-F) batteries on the built-in plate or from a lockable 7–34 V DC input, which the supplied D-tap cable links to a camera battery. Metal housings, a 0 to 40 °C operating range and a 1/4-inch thread for the articulating arm complete the hardware.

SWIT's placement advice is short and worth following: antennas pointing straight up even if a unit lies flat, receivers raised as far above the crowd as the rig allows, and nothing like walls, trees or water standing in the path. Three to four FLOW2000 systems can work at one location, enough for a multi-camera wireless setup at a sports venue or a conference with roaming cameras.

Packed in one carrying case are the transmitter, the pair of receivers, the camera arm with cold shoe and 1/4-inch fitting, the D-tap lead and two mains adapters. For a production house, it is one wireless kit that covers monitoring, recording and live switching from the same camera, rigged in minutes and packed away just as quickly.
