The Atomos TX 4K HD is a compact HDMI wireless transmitter designed for real‑time, cable‑free on‑set monitoring. It sends high‑quality video over 5GHz Wi‑Fi to compatible Atomos receivers, delivering a stable, low‑latency feed ideal for directors, focus pullers, and production teams who need flexible, untethered monitoring.
Supporting up to 4Kp30 and 1080p60, the TX provides a reliable wireless range of up to 150 m (500 ft) line‑of‑sight, ensuring smooth movement for camera operators while maintaining signal integrity. Its full‑size HDMI input works with mirrorless, DSLR, and cinema cameras, and USB‑C power allows easy integration with battery packs and professional rig power adapters.
Lightweight and easy to mount on cages or camera rigs, the TX maintains a minimal footprint while delivering professional‑grade wireless performance. When paired with the Atomos RX or Shinobi 7 RX, it forms a robust wireless video link for real‑time monitoring with minimal latency.
