Latency holds steady at around 32 ms. That is low enough for a director calling shots, for an operator whose picture goes straight to IMAG screens at a concert, and for multi-camera live switching where a wireless angle has to cut cleanly against cabled cameras. Before the feed reaches graphics, recording or the stream, the receiver re-clocks the signal and restores accurate colour, keeping black level and noise in check.

Embedded audio channels 1 and 2 travel with the picture from either input. Enough for camera-mic reference, a programme mix returned from the sound desk, or scratch audio for the edit.

On the radio side, the FLOW6500 relies on SWIT's KUWI technology with OFDM modulation in the licence-free 5 GHz bands. It is CE certified and complies with DFS (Dynamic Frequency Selection), which European rules require across much of the 5 GHz spectrum. Panel reception also copes better with obstacles than simple whip antennas, so the link holds up more reliably if a wall, a crowd or a temporary structure partly blocks the clear path.

One transmitter can feed any number of receivers in multicast mode. The FLOW6500 transmitter also talks to the rest of the FLOW family: a FLOW500 receiver picks it up at roughly 150 m and a FLOW2000 receiver at roughly 600 m. A production house already running FLOW kit can send one camera to the OB truck through the panel and, at the same time, to a director's monitor or a nearby client village through a smaller receiver. Several FLOW6500 pairs can also work side by side at one location.

Every transmitter and receiver is paired and protected by double encryption, combining SWIT's private transmission protocol with AES-128. At product launches, embargoed corporate events or closed-set drama, an unpaired receiver simply gets no picture.

OLED displays on both units show the video format, active channel and signal strength, and a five-way button on the transmitter handles channel changes on location without a laptop. Each unit accepts 7–34 V DC and draws no more than 9 W. Firmware updates install over USB, and the operating range is 0 to 40 °C.

The carrying case holds the transmitter, the panel receiver, a cold-shoe arm with a standard 1/4-inch thread, a D-tap to locking power cable and an AC adaptor with a 3 m lead.
