The ARRI WCU-4 Wireless Compact Unit is a 3-axis handheld controller featuring an integrated lens display. Control camera functions, focus, iris, and/or zoom from a distance, such as when shooting handheld or using a stabilizer, gimbal or crane. The WCU-4 is compatible with the ARRI ALEXA Mini, ALEXA Plus, and Studio cameras, and with ARRI UMC-4, SMC-1, EMC-1, and AMC-1 motor controllers. Camera functions are controllable for ARRI ALEXA Mini, Plus and Studio, and ARRI AMIRA when used with the UMC-4 motor controller.

The Watson Duo LCD Charger is designed specifically for digital camera and camcorder batteries. It has two bays and accepts up to two Sony L and M series batteries with the included interchangeable battery plate system. This allows you to use the same charging base but switch plates to accommodate other battery models.

The WCU-4 Plate from ARRI can be used to adapt the WCU-4 hand unit for tabletop use, to mount on a C-stand, or for mounting on an onboard monitor.
