ARRI release ARRI Hi-5: a fifth-generation intelligent hand unit

The new ARRI Hi-5 is one of the most sophisticated hand unit on the market, providing reliable wireless camera and lens control in demanding situations on set. Weatherproof and solidly built, it features an exceptional radio link range and unique, swappable radio modules for different territories and shooting challenges.

Replacing ARRI’s previous top-end hand unit, the WCU-4, and representing a significant step forward, the new Hi-5 is central to the fifth-generation ecosystem of ARRI’s Electronic Control System (ECS). Together with a new radio system, new intelligent batteries, smart focus rings, and an iOS app, the Hi-5 modernises on-set connectivity, simplifying complex tasks for film crews. Various of the new technologies incorporated into the design have patents pending.

Typically, the Hi-5 will be in the hands of a focus puller or 1^st AC, and ARRI has done everything possible to enhance their comfort and confidence. Proven ergonomics make the Hi-5 a pleasure to hold and operate, while the modern, stylish touchscreen interface, based on a camera GUI, will be instantly and intuitively familiar. Lens file management and software updates are faster and easier with the new ARRI ECS Sync App.

Most innovative of all are the swappable radio modules—a feature never before seen in a hand unit. With an often congested 2.4 GHz ISM band and different frequency regulations in different countries, the ability to exchange radio modules is a huge advantage, allowing crews to choose the module that best suits each shooting location.

ARRI will release three radio modules in the 900 and 2400 MHz ranges, using direct sequence and frequency-hopping spread spectrum technology to cut through interference. Together, they cover a multitude of shooting situations with a significantly improved, robust and long-range radio link, while ensuring backwards-compatibility with existing camera equipment. As technology evolves, even more modules can be added, making the Hi-5 a future-proof investment, able to accommodate future standards for on-set hardware communications.

Reliability of all features and functions was an overriding priority in the Hi-5’s design and construction, with particular attention paid to the ruggedised housing for operating in harsh environmental conditions. Sealed, dustproof, and weatherproof, the hand unit feels unmistakably solid the moment it is picked up, and will keep you shooting even when the elements are against you.

Various design elements of the Hi-5 are oriented towards maximising efficiency. Smart pre-marked focus rings now communicate directly with the Hi-5 hand unit, being instantly recognised and mapped to the lens focus scale. Batteries for the Hi-5 are ARRI products, based on the NP-L interface; they can be hot-swapped without powering the unit down, and their remaining capacity is always precisely displayed on the Hi-5 screen. Meanwhile, a new Tail Slate Mode prevents the user from stopping recording before capturing a tail slate on shots that need it.
