Gira 122400 Video Multiplexer for Door Communication, 2-Wire Bus, 4 Camera Inputs, DIN Rail, 6 TE

This Gira video multiplexer stands out by combining four camera signals from the door communication system onto a single 2-wire bus, eliminating the need for separate video cabling to each indoor station. It is a compact DIN-rail module that simplifies multi-camera installations in residential or commercial buildings.

Highlights

• Distributes and multiplexes video signals from up to four Gira camera modules
• Integrated video amplifier ensures stable signal quality over the bus
• Potential-free switching contact for additional control functions
• Mounts on DIN rail, width 6 TE (approx. 108 mm)
• Powered via the 2-wire bus or external 24 V DC

In daily use

Installers appreciate the straightforward wiring: camera modules connect directly to the multiplexer, and a single 2-wire bus carries video and data to all indoor stations. The switching contact can trigger a door opener or signal light when a call is active. With screw terminals and a slim 6 TE housing, it fits neatly into standard distribution boards.
