Doorbell: types, structural features, recommendations (23 photos)

Modern technology has affected virtually all facets of life, transforming and transforming even ordinary doorbells. A smart doorbell is not just a pleasant soundtrack, but also a whole range of additional functions that help to solve many goals.

New Features: Varieties and Features

The doorbell is a highly specialized device that signals the arrival of guests to the owners of the house. In total on the modern market you can find such varieties of these devices:

• Mechanical;
• Electric;
• Electronic.

For the front door in a private house or apartment, in fact, any of the above types will do. The choice of this or that device will be based solely on those requirements that potential customers put forward to the product. Consider the listed varieties in more detail.

Mechanical type doorbells

A mechanical doorbell to an apartment is the oldest type of warning device. Initially, these were simple bells on a string, which, if necessary, were set in motion.

More advanced mechanisms are represented by miniature knobs that launched the cam mechanism. Now, such a doorbell cannot be found anywhere, except in the form of an old-fashioned decoration in an outlandish exterior.

Electric doorbell

The electric doorbell is a combination device. The principle of operation of the device is based on a combination of mechanical and electrical elements.

Electric impulses are used to transmit translational movements to a special hammer. The latter, with its impacts on the resonator, produces a sound that signals the visit of guests to the inhabitants of the house.

Electronic door calls

The electronic doorbell device is the latest advancement in technology. Moreover, devices are just starting to develop, and are improving every day.

The devices do not have a single movable part. Principle of operation: the sound purity generator reproduces sound. At the same time, the sound is not primitive, but quite melodic.

There are several subspecies of electronic devices. Wired doorbells require connection to the electrical wiring of the apartment. A wireless doorbell usually runs on batteries. Sometimes manufacturers resort to using a miniature battery.

The latest fad is a doorbell with a camera or motion sensors. The device responds to human presence. No need to even press a button. As soon as a person enters a certain area, a sensor is triggered and a signal is given.

Wired installations with sound conditioners

A musical bell with two or more tunes works through a special speaker. Manufacturers often resort to the use of integrated circuits that supply different frequencies to the speaker. This causes the appearance of melodic trills.

A button is a trigger that triggers a trigger. The required voltage is no more than 12 V. This allows you to simplify the wiring diagram, use thinner wires, and also operate the device for an extremely long time.

The following advantages are characteristic of a smart musical call:

• Wide musical possibilities;
• Volume control;
• The owner of the apartment independently sets the duration of the sound signal;
• There is no high voltage in the button.

Advantages and disadvantages of different devices

Electromechanical devices are simple and straightforward. By this they bribe many. They are simple in terms of installation. The simplicity of design and the primitivism of the mechanism guarantee the durability of the device, which is also an undoubted advantage.

Among the shortcomings can be identified monotony and "annoyance" of the sound signal. If you want to change the type of signal will not work. Devices are connected only using electricity, which is also not always convenient.

A do-it-yourself wireless doorbell can also be easily installed. There is no need to drill walls, damage the decorative finish, spoil the exterior with "extra" wires. Modern devices are equipped with a hermetic case, which allows you to protect delicate mechanisms from water. Wireless calls connect anywhere, even if electricity is completely absent.

There are also disadvantages. The electronic system may not withstand sudden temperature changes and may fail. Wireless doorbells do not work if there are concrete or metal barriers between the two blocks. The farther the blocks are from each other, the worse the device works.

Designer refinements

The white plastic case is a classic look that is increasingly being ignored by manufacturers. Many potential buyers are trying to purchase a device that will look stylish, creative, decorate the exterior, emphasize one or another interior composition.

The case itself, buttons, and other auxiliary elements may be different in shape and color. Moreover, materials for decor can be very diverse. All kinds of imitations are especially popular: stone, suede, leather, wood texture.

Many calls can work on the basis of a voice recorder. A whole block of memory is allocated for recordings. If desired, you can record a greeting for those who come to the house. Battery-powered camcorders broadcast images in pretty good quality. Also, some models are complemented by a remote control mechanism used for country houses and cottages.

Video devices

Calls with a video camera are used as an ideal option for the price and operational characteristics for home use. The simplest built-in devices of this type can only identify the visitor and inform the inhabitants of the house about his arrival.

Such elementary systems for video surveillance retain their “original” function, transmitting a signal at the right time. Devices with a monitor of solid dimensions allow you to comfortably monitor the environment.

Progressive devices capture the necessary information in video and photo mode. Also, the owner of the house, if desired, can conduct video negotiations with the visitor. If the apartment owners are absent, the call can work in the “reverse mode”. Simply put, the device acts as a telephone "answering machine", if necessary broadcasting a message from the inhabitants of the house.

Other specifications depend on the modification of the device. It can be equipped with a miniature screen or a solid display, broadcast music, video, sound messages. If the device is built into the wall, it can be either completely invisible or very solid in size.

Mounting Features

Before you connect the doorbell, you must carefully study its design. Depending on whether the device is wired or wireless, preparatory activities will be determined.

Installing Wireless Models

Connecting a wireless doorbell does not take much time and effort. A few screws are screwed into the web on which the device will be placed. A button is installed on the outside of the door leaf, and the bell itself is located on the inside. Sometimes for fastening you can use double-sided tape.

Pre-placed in the device batteries. Sometimes, the device does not even need to be mounted anywhere. The bell is put on a shelf near the door, for example, where it will not bother anyone.

Install wired models

Wired models have two power outputs, to which wires from the distribution board should be connected, as well as two wires for supplying the button itself. Initially, you need to select a position for the device. It is best to place it above or to the side of the front door.

At the point where the bell will be mounted, the wall is ditched, and then a power supply is laid. If the wall cannot be damaged for some reason, the wires are laid superficially, fastening the elements with brackets.

The hole is made in the hole of the door or in the wall, near the entrance to the apartment. A strob is punched up to the button. It is better if the button is attached to a wooden panel or plate. Then lay the cable in the wall, as well as to the distribution panel.

Terminals are needed to connect the call leads to the power wires and to the power details of the button itself. All manipulations are carried out only when the voltage is disconnected from the mains.
