Fermax says DUOX is the world’s first fully digital video intercom system engineered from the ground up over 2 non-polarised wires reducing the overall project cost and minimising installation times.
DUOX is a full digital system over 2-wires built to withstand external interferences capable of distances up to 500m between devices and 999,999 apartments. DUOX excels at mixed audio and audio/video installations as well as upgrading from audio to video as the backbone infrastructure remains the same, all transmitted over 2 non-polarised wires.
DUOX is compatible with a wide range of cables, including Cat5/6, which also makes it great for retrofits and upgrades. DUOX can be connected in star-wired or daisy chain configuration for ultimate flexibility. You can check out the turbo-charged programming here.
