The first electric doorbell was invented in 1831 by Joseph Henry. Then it has come a long way and evolved from buzzers to musical chimes to a part of an intercom system. Doorbells are utilized to greet visitors as well as announce the arrival of a visitor. When the button was pushed on, the doorbell might signal music or a chiming sound even allow the person at home to speak with someone at the other end of the intercom system.

As for the evolution of doorbells, both the sound and the appearance of doorbells have changed a lot. In addition,  wired doorbells, wireless doorbells and doorbells incorporated into voice and video intercoms are all available nowadays. Actually, apart from informing the arrival of a guest, some doorbells have other functions, such as the pet doorbell system which alerts owners when the pet gets close to the door.

And it doesn't matter which  wire is connected to which connector.
