Intercoms and call panels with wired analog connection

Wired (analog)

— classic scheme in which the signal is transmitted via cable directly without digitization, usually through a 4-core or coaxial cable. This type of connection is simple, stable, and does not require network infrastructure, making it a reliable solution for basic systems. It provides the transmission of video, audio, and control signals (lock unlocking) with minimal delay but is limited in functionality—no remote access, integration into IP systems, or high-resolution transmission. Suitable for inexpensive or already existing analog installations.
