In recent decades, wireless doorbells have become popular, to avoid the expense of running wires through the building walls. The doorbell button contains a built-in radio transmitter powered by a battery. When the button is pushed, the transmitter sends a radio signal to the receiver unit, which is plugged into a wall outlet inside the building. When the radio signal is detected by the receiver, it activates a sound chip that plays the sound of gongs through a loudspeaker—either a two-note "ding-dong" sound, or a longer chime sequence such as Westminster Quarters. Frequencies in the 2.4GHz ISM band are usually used. To avoid interference by nearby wireless doorbells on the same radio frequency, the units can usually be set by the owner to different radio channels.

The video is typically recorded via Wi-Fi to a cloud internet service, meaning that if the unit is tampered with, damaged or stolen, then this recording will still be captured and can be analyzed to determine the identity of the responsible party.

Some models even offer a dedicated mute function or options to silence the doorbell for a set period of time. Mechanical doorbells by Brian D. Coleman and H. Weber Wilson. Old House Journal, May-June 2000. Of course, people still had doorbells before electric power became commonplace in our homes. For those who like retro technology, here's a fascinating article about crank, twist, and T-lever mechanical doorbells.

As with wireless doorbells, musical doorbells have also become more common. Musical and continuous power doorbells serve as an attempt to bridge the gap between newer digital circuitry and older doorbell wiring schemes. A major difference between the standard setup of a wired doorbell and a musical doorbell is that the musical doorbell must maintain power after the doorbell button is released, to continue playing the doorbell song. This can be achieved in one of two ways. For simple single-pole, single-throw doorbell buttons, the chime device employs a rectifier diode and ballast capacitor at the voltage input stage of the circuit. Upon pressing the doorbell button, power is connected through the rectifier diode or series of rectifier diodes called a full wave rectifier, which allows the current to flow in only one direction, into the ballast capacitor. The ballast capacitor charges at a rate far greater than the rest of the circuit needs to complete a given song. Once the button is released, the capacitor retains the charge and maintains power for a short duration to the rest of the circuit. On the subject of range, some wireless doorbells now promise to reach 100m to 400m. The larger your property, the greater range you will require, but 400m is ample to cater for a sizeable place so you’re unlikely to need anything more than that.

For the sake of simplicity, this picture doesn't include the electromagnet and the battery (which are wired into the circuit) or the spring that pulls theIn many instances, the solenoid piston consists of an iron core mounted to a non-magnetic metal bar. When there is no power to the electromagnet, a spring pushes the piston to the left, and the iron core extends outside of the wire coil. When you turn the electromagnet on (by pressing the doorbell button), the iron core is drawn to the magnetic field, so it slides into the center of the coiled wire. process repeats until you let go off the button.
