4-Series™ Control System

Provides a compact 4-Series™ control system featuring the Crestron IFE micro form factor. Conveniently powered via PoE and fits almost anywhere to suit a variety of specialized applications.
The Crestron® RMC4 provides a secure, high‑performance, cost-effective control processor and interface for controlling and monitoring for a single display device, a small AV system, lighting and shading, climate control, security, energy management, and many other specialized applications. A small form factor allows the RMC4 to be placed just about anywhere, with the option to attach it to a flat surface or DIN rail using the included mounting bracket. The RMC4 can fit easily behind a video display or above a projector, and provides enough control ports to control the display device along with a screen or lift.
