ALEXA Remote Control
An optional software license will enable you to remote control all ALEXA Plus type cameras, except the ALEXA HD Plus. This includes setting frame rate, shutter angle, exposure index, false colour on the monitor output, and more. Extended camera status information is also available, allowing you to quickly check your camera settings at any time.
Tactile vibrating feedback lets you keep your eye on the action in the most challenging situations. Operators can concentrate on the scene, knowing that the hand unit will vibrate to prompt them when focus markers are reached.
Back-lit Focus Knob
The super-smooth focus knob contains an integrated light source that shines through the wide, optionally pre-marked focus ring in low light conditions, thus providing clearly readable focus marks at all times. The friction of the focus knob can be easily adjusted to one’s personal preference without any tools.
Easy-to-Read Lens Data Display
Clearly arranged, easy-to-read lens and camera information is available on the large 3” display, along with data from optional ultrasonic distance measurement devices. The transflective display technology ensures perfect readability in all ambient lighting conditions.
Pre-Marked Focus Rings
Lens scales can be mapped to a set of high quality pre-marked focus rings in metric or imperial scale.
The WCU-4 user button can be configured to activate focus tracking - setting the focus motor to continuously follow a subject by using an ultrasonic distance measurer. Focus tracking works with ARRI's Ultrasonic Distance Measure UDM-1 and the Universal Motor Controller UMC-4.
Various parameters of the WCU-4 can be set up to one’s personal preference. These include the display arrangement, vibration patterns and programmable user button, to name just a few. You can save your preferred settings on an SD card, enabling you to immediately personalise any WCU-4, anywhere in the world.
Exceptional Quality and Service
The WCU-4 is completely splash-proof and embodies the reliability and durability for which ARRI is famous. Wear and tear parts are replaceable at rental level, and the worldwide ARRI Service network ensures rapid second level support if needed. New firmware versions can be installed to the unit via SD card within seconds.
