On set the camera keeps moving, while the director, focus puller and client all need to see the same picture. A trailing HDMI cable limits camera moves and trips people up. Here a TX transmitter sits on the camera shoe and each viewer holds a monitor with an RX built in. One transmitter feeds several receivers, and the wireless tier is chosen by the distance between camera and monitors.
Handheld, gimbal and dolly shots change position all the time. An HDMI cable on the floor limits movement and gets stepped on by cast and crew. Under strain the connector works loose, and when the picture drops the take stops.
The director watches framing and performance, the focus puller watches focus, and the client and producer watch from the monitor area. Splitting one feed by cable means several runs, and they never stretch far enough once people move.
On location, in large venues or at events, the monitors can be tens to hundreds of metres from the camera. HDMI won't reach, and longer cables or extenders add more wiring and more things to fail.
Once the transmitter takes the camera's HDMI output, the operator's own monitor still needs a signal. Adding a splitter puts yet another box and cable on the rig.
The TX transmitter mounts on the camera shoe and takes the camera's HDMI output. The director, focus puller and client each hold a receiver monitor showing the same feed, with no distribution cables on set.
Wireless range comes in three tiers, roughly 30-100 m, 100-300 m and 300-1000 m, chosen by the distance from camera to monitors. The tier does not affect resolution; every tier runs 4K60. Ranges are line-of-sight references to be confirmed with samples.
The 4K30 module has a built-in HDMI loop-out (up to 4K30), so the operator's monitor can plug straight into the transmitter. With the 4K60 module, an HDMI splitter chip on the carrier board provides 4K60 loop-out.
Audio embedded in the camera's HDMI travels in sync with the picture. The RX has an analog audio output, and plugging headphones into the receiver monitor switches to them automatically, so the director and sound crew can watch and listen.

Cabling hassle and adapter chaos in meeting rooms, especially with BYOD guests.
View solution →KVM ExtensionThe host must live in a rack or server room while the operator sits tens of metres away.
View solution →Portable DisplayPortable monitors still need an HDMI or Type-C cable to the source, which gets in the way when moving around or sharing the screen.
View solution →Wired & FiberBetween buildings, across a site or in heavy RF interference, wireless cannot reach and HDMI cable cannot run that far.
View solution →Pro DisplayWorkstations, graphics cards and pro monitors mostly use DisplayPort. Going wireless means stacking DP-to-HDMI adapters, which is messy and hard to keep compatible.
View solution →Mobile CastingLaptops, tablets and phones often have only USB-C, so casting starts with hunting for an adapter, and guest devices in meeting rooms and showrooms vary widely.
View solution →DockingLaptops have few ports, so monitors, keyboard and mouse, Ethernet and charging all need adapters, and casting in a meeting room means carrying yet another dongle.
View solution →In-Car ConnectivityThe head unit only supports wired CarPlay, so the phone has to be plugged in every trip, and rear passengers end up passing phones around to share content.
View solution →Medical & IndustrialMobile probes tangle cables; routing between operating room and lecture hall is restricted.
