The ARRI RF-900 Radio Module 900 MHz FHSS is an interchangeable long-range radio module designed for use with the Hi-5 Lens Control Hand Unit and the RIA-1 Radio Interface Adapter. Utilizing frequency-hopping spread spectrum (FHSS) technology, it delivers a robust, interference-resistant wireless connection for reliable lens control in demanding production environments.

When operating in network mode, the RF-900 enables point-to-multipoint communication, allowing up to three hand units to connect to a single camera. This makes it easy to split focus, iris, and zoom control among multiple crew members for efficient, collaborative operation on set. Optimized for extended range and stable performance, the RF-900 is certified for use in the USA and Canada only and is ideal for professional cinema workflows requiring dependable wireless control.
