From Landlines to Door Entry: Why 4-wire Analogue Systems Still Ring True

Think landlines, televisions, and door entry systems. Why are 4-wire analogue systems still so popular?

In the age of 4K streaming and super-fast internet speeds thanks to fibre optics, analogue television largely seems like a relic of the past—yet analogue systems are here to stay!

As early as the aughts, many countries began to transition away from analogue television broadcasting. Analogue systems, with their limited average 6-megahertz bandwidth, were increasingly outmatched by the emerging demands of contemporary digital applications. As the world embraced digital technologies requiring higher data transfer rates, the need for analogue television became irrelevant.

While we all know about traditional television, analogue 4-wire systems are not entirely obsolete, especially in the context of door entry.
