Alexa SXT EV and SXT Plus owners will have the option to upgrade

Arri will be upgrading the Alexa SXT platform to an entirely wireless camera system by integrating a low-latency HD video transmitter and WiFi radio into its new Alexa SXT W model.

The Alexa SXT W ("W" for "wireless") will replace the Alexa SXT Plus and Alexa SXT Studio models. There will be options to upgrade for existing SXT EV and SXT Plus owners.

Having a video transmitter built into the ALEXA SXT W makes the camera smaller and lighter than it would be with an external transmitter, says the company. The integrated WiFi radio also offers the option for wireless colour management on set and wireless camera remote control with the Alexa Web Remote. Additional WiFi features are also in development. 

The Alexa SXT W is part of the new ARRI Wireless Video System (WVS), along with a stand-alone video transmitter for use with other cameras such as the ALEXA Mini, and a stand-alone video receiver for receiving signals from either transmitter. An extensive accessory range includes mounting brackets, antenna extensions, the handheld Director’s Monitor Support (DMS-1), and a Transvideo monitor with a built-in receiver for the Arri transmitters.  

"Our wireless video uses technology from market leader Amimon, with special hardware and software modifications to comply with Arri's stringent performance and quality requirements," said Marc Shipman-Mueller, Alexa Product Manager. "But that is not all; the wireless video system works harmoniously with ALEXA SXT’s other radio-based offerings – the WiFi and our own proprietary camera and lens control system – avoiding time-consuming interference between the radios on the camera."
