Wireless video
Wireless video transmitter and receiver sets that cut the cable between the camera and the director, client or focus puller.
How to choose a wireless video transmitter
Range, honestly. Published range figures are line-of-sight with nothing in the way. Walls, bodies and a busy 5 GHz environment all cut it. Pick a system with headroom over your worst case, not your best.
Latency. Anything above a few frames is unusable for focus pulling and awkward for a director. Sub-frame latency is what the Pyro series and the Atomos TX/RX pack are built for.
Resolution and inputs. Pyro S and Pyro H handle HDMI; Pyro Ultra and Cosmo C1 and C2 add SDI and 4K. Match the transmitter to what the camera actually outputs.
Receiver count. Most systems support several receivers from one transmitter — that is how the director, the client monitor and the focus puller all see the same feed. Check the maximum.
Power and mounting. These run on NP-F or built-in batteries and need a mount on the cage. Antennas matter: Hollyland's soft antennas and paddle antennas change the pattern, and a broken antenna is the most common failure.
Hollyland supplies 8 records, Atomos 3 including the TX 4K/HD and RX 4K/HD pair. Hollyland's Pyro 5, Pyro 7 and Mars M1 monitors in monitors and recorders have receivers built in, which removes a separate box from the rig.
