The Wireless Compact Unit WCU-3 is an affordable all-in-one remote control for camera on/off, focus and aperture. The Zoom Main Unit ZMU-3 can be also attached with an optional bracket. The WMU-3 is fully compatible with the existing ARRI Wireless Remote System WRS.

Special attention has been given to ergonomics and durability, with features like an adjustable handgrip, backlit buttons, an illuminated index scale, optional cabled or wireless operation, and sealed precision optical encoders for the manual controls. The modern, backlit color TFT display shows the camera and lens status.

The WCU-3 directly communicates with the ARRI ALEXA Plus.
