Seen at BSC Expo 2020, ERM Radio Modules by FoMa Systems let you work with ARRI and cmotion hand units, as well as SRH Remote Heads, at greater wireless distances from the camera.

The ERM system works in pairs: one as a transmitter and the other as a receiver, using spread spectrum frequency-hopping technology for a long range and secure conncection. The rugged housings are built to withstand rough setups and car rigs, as they did on Ford v Ferrari and Fast & Furious 9.

There are 3 versions:

• ERM-2400 LCS has a 1,000 m / 3,280 ft range, operates on 2400 MHz, and extends the ARRI WCU-4 or SXU-1 Hand Unit connection to camera over air.
• ERM-2400 SRH also has a 1,000 m / 3,280 ft range and operates on 2400 MHz. It pairs ARRI’s SRH Remote Control Panel with ARRI SRH-3 and SRH-360 stabilized heads.
• ERM-900 has a longer 3,000 m / 9,840 ft range, operates on 900 MHz, and pairs ARRI’s SRH Remote Control Panel with ARRI SRH-3 and SRH-360 stabilized heads.

The ERM-2400 LCS package consists of a paired set of 2 radio modules, including necessary cables. Once connected to the hand unit and camera, they will power up and connect automatically.

The modules can be used both as transmitters and receivers.
Pre-configured pairs can be identified by their matching number code at the back of each device.
