Software Update Package (SUP) 4.3.26 for ARRI Wireless Video System (WVS)

WVS Software Update Package (SUP) 4.3.26 is now available for 

  • ARRI WVS transmitters in ALEXA LF and ALEXA SXT W cameras
  • ARRI Wireless Video Transmitter WVT-1 and
  • ARRI Wireless Video Receiver WVR-1.


WVS SUP 4.3.26 improves the reliability and signal robustness of the integrated wireless video transmitters within ALEXA LF and ALEXA SXT W cameras. These cameras’ internal transmitters were not able to supply full transmission power to the antennas with older WVS SUPs.

Note 1:
This issue does not affect the stand-alone Wireless Video Transmitter WVT-1 and the Wireless Video Receiver WVR-1.

Note 2:
In some cases it is possible for the antenna cable inside the camera to have an intermittent connection to the antenna connector. ARRI service can check and, where needed, exchange the antenna cable free-of-charge.

Note 3:
Both the WVS SUP update and the antenna cable check are part of the free-of-charge "ALEXA LF 3.0 SW & HW Upgrades". We encourage owners of ALEXA LF cameras to send their cameras into service to upgrade to 3.0. Please schedule an appointment with your local service center:

Note 4:
From August 27, 2018 on, all ARRI Wireless Video System devices have been shipped with WVS SUP 4.3.26 and ALEXA LF and ALEXA SXT W cameras have the new antenna cables installed.


Cameras and electronic devices should always run the latest SUP to enable you to benefit from the latest improvements, features and bug fixes.
