Connections on the transmitter are 3G-SDI in with a loop out, plus a full-size HDMI input. Feed both and SDI takes priority. On the receiving side, a pair of 3G-SDI outputs sits next to HDMI and USB-C capture, all live at once whichever input is in use. An HDMI-only mirrorless body therefore reaches the gallery on BNC. On an SDI camera, the loop output keeps an on-board monitor or recorder running.

That USB-C port is a UVC capture output. A laptop sees the receiver as a camera, with no driver needed on PC or Mac, and OBS picks it up as a video capture device at 1080p50/60. For a quick live stream or a press-conference feed, the capture card stays in the bag. A phone or tablet running a third-party USB camera app can take the same signal, giving a producer a pocket monitor on the floor.

One transmitter serves up to four receivers in multicast, with no drop in distance or image quality and no added delay, according to SWIT. A typical split on a commercial: DP, focus puller, director and a wireless video monitoring feed for the client. Every CREW-family transmitter and receiver is cross-compatible, so NP-F units or the 3 km panel receiver from the MAX kits can join the group later.

Bigger sites are covered too. SWIT lists up to eight pairs working together, as long as every set has a valid input signal, and white and yellow antenna tags keep each group identifiable at a glance.

Instead of Wi-Fi, the link uses the KUWI 2.0 Pro chipset and SWIT's own radio protocol, which leaves phones and venue networks alone. It works across SWIT's licence-free 5.1–5.9 GHz range (5.17–5.69 and 5.75–5.83 GHz segments), DFS compliant, at 23 dBm with OFDM modulation.

In Auto, the link scans continuously and hops frequency without breaking the picture. Frequency coordinators can fix the channel by hand on the transmitter, and the receivers follow. For paths through partitions, the mode menu swaps High Quality for a stronger wall-crossing setting. That change needs a transmitter restart, so set it during prep.

Security is layered: the closed KUWI protocol plus AES-256 encryption, worth having on an embargoed product launch. Over SDI the link also passes camera metadata for DIT live grading, along with timecode and the camera's record trigger, so a monitor or recorder on the receiving side can follow the camera. The image carries 2-channel embedded audio as well.

Daily handling is quick. Paired units relink by themselves at power-on. A sunlight-readable 450-nit OLED and a joystick on each unit handle pairing, fan and firmware, while channel and mode are set from the transmitter. Its screen shows how many receivers are connected; the receiver shows signal strength. The fan runs in Auto or switches off for quiet takes, and firmware loads from a USB stick through the OTG adapter.

Beyond the V-mount plates, each unit takes 7–17 V DC on a 2-pin LEMO and USB-C power: 9 V/2 A for the transmitter, 5 V/2 A for the receiver. Consumption is 16 W and 6 W respectively, with an operating range of −10 to 40 °C. The carrying case holds both units, both antenna sets, antenna tags, a pair of D-Tap to 2-pin LEMO leads, two USB-C cables and a USB-A to USB-C OTG adapter. SWIT also lists a CE certificate for this model, handy for venue paperwork in Europe.
