The ARRI Wireless Video System (WVS) forms one element of ARRI’s complete Electronic Control System, itself part of the company’s Pro Camera Accessories range. Allowing crews to wirelessly transmit camera images to various on-set monitors, the WVS consists of the HD video transmitters in ALEXA LF and ALEXA SXT W cameras, a standalone transmitter for use with other ARRI or third-party cameras, and a standalone receiver that picks up signals from either transmitter.
In March 2019, a new receiver was added to the WVS product line: the WVR‑1s. Smaller and lighter than ARRI’s long-range WVR‑1 receiver, the WVR‑1s is particularly well suited to handheld configurations. Focus pullers will combine it with the ARRI WCU‑4 wireless hand unit and a small onboard monitor, reducing the bulk and weight of their remote focus setup. Directors will pair it with just a handheld monitor, keeping their eyes on each take as it happens, even when on the move, or in challenging locations.
