Modern technology has affected the actual 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 solve many goals.
New features: types and features
The doorbell is a highly specialized device that signals the arrival of guests to the owners of the house. In total in the modern market it is possible to meet such kinds of these devices:
For the front door in a private house or apartment in fact fit any of the above types. The choice of a device will be based solely on the requirements put forward by potential buyers. Consider the listed species in more detail.
Mechanical type door bells
The mechanical doorbell to the apartment is the oldest type of alarm device. Initially, they were simple bells on a string, which, if necessary, were set in motion.
More advanced mechanisms are represented by miniature cranks that trigger the cam mechanism. Now such a doorbell is nowhere to be found, except in the form of ancient scenery in a strange exterior.
The electric doorbell is a combination device. The principle of operation of the device is based on a combination of mechanical and electrical elements.
Electrical impulses are used to transmit progressive movements to a special hammer. The latter, with its strikes on the resonator, produces a sound that signals the visit of the guests to the inhabitants of the house.
Electronic doorbell device is the latest achievement of technology. Moreover, adaptations are just beginning to develop, and are improving every day.
Devices do not have any movable parts. Principle of operation: a 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 apartment wiring. Wireless doorbell usually runs on batteries. Sometimes manufacturers resort to using a miniature battery.
The last squeak of fashion is the 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 zone, a sensor is triggered and a signal is heard.
A musical bell with two or more melodies works through a special speaker. Manufacturers often resort to the use of integrated circuits, which feed different frequency vibrations to the speaker. This causes melodious trills.
The button is the trigger that triggers the mechanism. The required voltage is not 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 clever musical call:
- Wide musical possibilities;
- Volume control;
- The owner of the apartments independently sets the duration of the sound signal;
- There is no high voltage in the button.
The advantages and disadvantages of different devices
Electromechanical devices are simple and uncomplicated. With this they bribe many. They are simple in terms of installation. The simplicity of the 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 audio signal. If you want to change the type of signal will not work. Connect devices only with the help of electricity, which is also not always convenient.
Do-it-yourself wireless doorbell can also be easily installed. There is no need to drill the walls, damage the decorative finish, spoil the exterior with "extra" wires. Modern devices are equipped with a hermetic case that allows you to protect delicate mechanisms from the ingress of water. Wireless calls are connected anywhere, even if the electricity is completely absent.
There are drawbacks too. The electronic system can not withstand sudden temperature changes and fail. Wireless doorbell types do not work if concrete or metal barriers are located between two blocks. The further blocks are located from each other, the worse the device works.
The white plastic case is a classic look that is increasingly ignored by manufacturers. Many potential buyers are trying to purchase such a device that will look stylish, creative, decorate the exterior, emphasize one or another interior composition.
The body, buttons, and other auxiliary elements may be different in shape and color. And the materials for the decor can be very diverse. All kinds of imitations are especially popular: stone, suede, leather, woody textures.
Many calls can work on the principle of a dictaphone. Records are allocated a block of memory. If you wish, you can write a greeting for those who come into the house. Devices with a video camera, battery-powered, broadcast the image in pretty good quality. Also, some models complements the remote control mechanism used for country houses and cottages.
Video camera calls are used as an ideal option for price and performance for home use. The simplest embedded devices of this type allow only to identify the visitor and inform the inhabitants of the house about his arrival.
Such elementary systems for video surveillance retain their “original” function, transmitting the signal at the right moment. Devices with a monitor of solid dimensions allow you to monitor the environment in a comfortable mode.
Progressive devices record 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 owners of the apartments are absent, the call can work in the "reverse mode". Simply put, the device performs the function of a telephone "answering machine", if necessary, broadcasting a message from the inhabitants of the house.
The remaining characteristics depend on the modification of the device. It can be equipped with a miniature screen or a solid display, broadcast music, video, audio messages. If the device is built into the wall, it can be both completely invisible and very solid in size.
Before you connect the doorbell, you need to carefully examine its design. Depending on whether a wired device or wireless, preparatory activities will be determined.
Installing Wireless Models
Connecting a wireless doorbell does not take much time and effort. In a cloth on which the device will be placed, several self-tapping screws are screwed. A button is installed on the outside of the door leaf, the bell is placed on the inside. Sometimes for fastening you can use double-sided tape.
Pre-placed in the device batteries. Sometimes, the device doesn't even need to be fixed anywhere. The call is placed on the shelf near the door, for example, where it will not disturb anyone.
Installing wired models
Wire models have two power leads to which wires from the switchboard should be connected, as well as two wires for supplying the button itself. Initially, you must select a location 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 will be stitched, and then a power supply will be laid. If the wall cannot be damaged for some reason, the wires are laid superficially, attaching elements with brackets.
The hole is made in the hole of the door or in the wall, near the entrance to the apartment. Up to the button pierce the strobe. 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 required to connect the findings of the bell with the power supply wires and the power supply details of the button itself. All manipulations are carried out only when the voltage is disconnected from the mains.
