USB-C on the receiver is a UVC video capture output. A Windows PC or a Mac detects the receiver as a standard camera, no driver required, at 1080p50/60, and OBS lists it among its capture devices. A shareholder meeting, a webinar from a hotel ballroom or a remote-guest insert can go out from a laptop on one cable. Through a third-party "USB camera" viewer app, a tablet or phone turns into a monitor for a client watching from the back row.

Radio is handled by SWIT's KUWI 2.0 Pro chip running a proprietary protocol, not Wi-Fi. The link uses the licence-free 5 GHz band (5.17–5.69 and 5.75–5.83 GHz), meets DFS rules and modulates in OFDM (BPSK, QPSK, 16QAM, 64QAM) with 23 dBm output. A built-in scanner checks the band and settles on the cleanest channel. In Auto, the system keeps hopping frequency without breaking the image; a fixed channel can be set when an RF coordinator hands one out.

Range depends on antennas. The standard soft-base 3 dBi set reaches roughly 900 m with clear sight between units, and the four 5 dBi backup antennas packed with the kit lift that to 1.2 km while holding the signal better through walls. The manufacturer's field advice is to keep the antennas vertical, mount the receiver up high and point it toward the camera position, with no trees or water across the path. A touchline camera feeding an OB van gains a lot from that placement.

Channel and image-quality mode are set from the transmitter menu, and the receiver takes them over on its own. A low-latency setting and a sturdier wall-crossing setting cover the two typical cases: a clear outdoor path, or a director watching an interview from the next room.

The kit begins as one transmitter and one receiver, yet multicast lets a single transmitter feed as many as four receivers, and SWIT claims neither distance, delay nor image quality suffers. Every CREW-family unit is cross-compatible, whether it carries an NP-F plate, a V-mount or the large panel antenna. Pair this transmitter with the CREW MAX panel receiver and the path grows to 3 km. Up to eight pairs can run on one location, and coloured clip-on tags, white and yellow, make it obvious which monitor is paired with which camera body.

Two layers guard the feed: SWIT's proprietary KUWI radio protocol, then AES-256 encryption applied to the video itself. A music video before release or a confidential keynote rehearsal reaches paired screens only.

Both units carry a 450-nit OLED that stays readable in direct sun, plus a joystick for pairing, channel, fan and firmware. The transmitter counts connected receivers; the receiver shows signal strength and reports "unlink" if the path drops. Once paired, the two units relink automatically each time they are switched on.

For power, each unit offers an NP-F battery plate compatible with Sony L-series packs, a 2-pin LEMO socket taking 7–17 V DC, and USB-C (the transmitter asks for 9 V/2 A, the receiver for 5 V/2 A). The transmitter consumes 16 W, the receiver 6 W, and the operating range runs from −10 to 40 °C. The fan follows internal temperature or stops for quiet takes, thermal protection stays active, and the transmitter is housed in metal.

A firmware package copied to a flash drive installs over the OTG adapter. SWIT also sells an optional mains adapter with 12 V output on LEMO, handy for a receiver that stays at video village all day.

Packed in the SWIT CREW carrying case: transmitter, receiver, four backup high-gain antennas, four white and four yellow tags, two cables from D-Tap to 2-pin LEMO, two USB-C to USB-C cables and an OTG adapter from USB-A to USB-C. With a D-Tap lead for each end, both units can run from camera or block batteries as soon as the case is opened.
