But this does not mean that from now on the person is a hostage of the system. When needed he can control everything by using remote controls, or controlling panels built-in the walls. Also you can control stability through smart phone, lap top or PC.system is also able to control effective usage of resources. When sensor detects enough light in the room it automatically turns off all the lights that are not needed now. Motion detector will turn on the light when you enter the bathroom or cellar, and timer will turn it off after some time if it will not detect any motion for set period of time.house can have decentralized system or system which is controlled by one central computer. The former means that system does not have any central point where all signals are gathered and analyzed. In this case all devices are connected to one common line. With the help of this line all devices communicate with each other. To think, all switches in smart house are the elements of the system. In a common house without this system, the switch just closes the contact. While in smart house, pushing on the button sends a signal to a lamp and there it is decides whether to make light brighter or vice versa to make more romantic atmosphere. In the second case, when smart house has centralized system, all the detectors send the data to the central computer. This computer processes everything, analyzes and then makes a decision. Smart house feels and analyzes everything what is happening in the house and outside of it, and corresponds to it respectively. The only disadvantage of this system for this moment is that it is very expensive and not each of us can afford it. (Building Management System.)
Smart House works
, ZigBee and Z-Wave just provide the technology for smart house communication. Manufactures made alliances with these systems to produce products that will support the technology. For example cameras, with their help person can watch every sector of his house. Video door phone will help you to see who is knocking on your door without standing up from the sofa. You just need to turn on special channel on TV and that is it. From the same position just with a help of remote control you can open the door.sensors. Motion sensors can really help you in saving electricity. When sensor does not detect any motion in the room, it automatically turns off the light and all unnecessary devices. Sensors are developed so much that they even can distinguish pets from thefts. But if you have smart house thefts will not be to enter it, because every smart house has security system. When you leave home you turn on the security mode or you can program your system to turn on security mode right after when the door closes after you.through which you can control all the processes in house:
Remote control
Keypad
Computer (even if you are in the office, by using internet you can see what is happening in your home)
Mobile phone
Wall panels.
One more good thing about smart houses is that you can have as many or as little devices as you want. Everything is up to the owner of the house. But person should be very careful, if he uses devices that work on the same system, no matter it is from different manufacturers or from one manufacturer, it is ok. But if he wants devices that work on different systems he will need bridging device.
Multiroom
To increase the sense of comfort, designers came with an idea of multiroom. Multiroom system- is a system of transferring audio or/and video signal from one or several sources, which are situated in one room, to the acoustic systems and TVs in every point of the house. The access to the system can be from any room. As was mentioned before, each room is equipped with an built-in wall sensor panel, which has all the controls in itself. If you want to change the song you can just come to this panel and change it, without going to the room where the source is. Moreover if you have remote control, you can change it even from the coach.this system helps not only to decrease expenses for expensive equipment. It also solves the problem of installing this in the rooms where it is impossible.example if you want to listen to your favorite music while taking a shower, without multiroom you will need to put speakers there, isolate all wires and etc. But if you use multi room this is not problem anymore. Speakers are waterproof and built-in ceiling. And if you have waterproof TV you can even watch videos while lying in the bath.using this system you can create special atmosphere in each room, or in the house as a whole. You can vary the music in each room or groups of rooms. By putting favorite pleasant music on the background you create your own comfort. And everything is controlled by panels on the wall or by remote control.exist not only as a part of smart house but also as a separate system, which can be installed in usual apartment. Some people call multiroom as a smart house for non rich. The main difference between smart house and multiroom is that you can use all the abilities of this room right after installation and you have all necessary conditions into its future development. It means that you can buy the simplest multiroom system at the beginning and the year by year develop it by adding new devices and improving old ones.system in not just-in house system. It can be also applied in the garden. So when you want to sit outside of the house you still can control what do you want to listen to.multirooms developed to the system that allows you not only for transferring audio or/and video signals, but also for communicating from room to room. From living room you can video call to your wife in kitchen and ask what is for dinner today. Also this system is used to see who came to your house. When visitor rings the door bell the camera turns on automatically, so that from your sofa you can see who is your guest.
Despite this system looks very complicated it is very easy to use. Wall panels have very simple interface which can be understood by anyone. (Multiroom Systems.; Что Такое Multiroom? [What is Multiroom?].)
price of smart house
you decide what devices to put n your house, the price also varies. One builder estimates that his clients spend between $10 000 and $250 000 for sophisticated systems. If you build the smart home gradually, starting with a basic lighting system, it might only be a few hundred dollars. A more sophisticated system will be tens of thousands of dollars, and elements of home theater systems raise the cost of a system about 50 percent. (How Smart Homes Work: Setting up a Smart Home.)an example of how the smart house can look like I want to make a small excursion to the house of one of the most well-known person in the IS sphere - Bill Gates.
to the most expensive smart house in the world
the one of the banks of Washington lake (suburb of Medina, Washington) there is a beautiful house. The price of this house is $55 000 000. Why is it so expensive? Because this is a house of the Microsoft king Bill Gates. It looks like 4 floor building, but in fact there are 8 floors, 4 of them are under ground. Economically this project is reasonable because in USA you pay taxes for the area which is on the ground, and do not pay for underground area. More than 3500 sq meters include twelve rooms, 24 bathrooms, basin, home cinema, library, dance room and picture gallery.underground part of the building is also supplied with daylight. For this purpose there was built 84 kilometer long cable made of optical fiber. On the 4th floor there is an energy supply system. Even if the electricity in the district will go down Mr. Gates still will be able to watch TV. The security of Microsofts king is provided by skillfully hidden cameras (there are about 50 of them). There are also 2 cameras that detect the car number when it enters the gates or passes by.
Everyone who is inside the house has a pin with RFID ( Radio Frequency Identification). If you want to enter the house you need to get such pin from the security, which is not so easy. And after you receive this pin you will have access only to some rooms. For other rooms doors will be closed for you. Identification of the RFID gives for Mr. Gates great opportunity to show his hospitability. Because with this pins he can program that your favorite music or sound effect will follow you in every room of the house, the illumination will be set according to your preferences and even the smell in the room will be your favorite rose or chocolate.of the house can enjoy the beautiful paintings of famous painters such as Van Gogh or Rembrandt. These paintings are shown on the plasma panels. They can also visit picture gallery where Gates keeps some original paintings. But for very rare and valuable paintings access is limited. If the guest turn offs the route, the system will immediately detect it, by reading information from RFID pin and will inform the host with a very loud sound signal.the grass and bushes in front of his house have their own watering system. Each bush is watered with a set amount of water with set pressure.building this house Bill Gates spent 7 years. The best US building company did everything to implement the dream of their famous client. The result is a perfect system, which is controlled by hundreds of computers, by three professional securities and one engineer. Systems of water cleaning provide house with clean water, air-conditioners make the air in the house fresh, vacuum cleaner robots clean the house.people will say, what if something will go wrong? The whole house then will be in chaos. But smart projectors of this house predicted this thing too. If something will happen with a system (which is unlikely to happen) each device has its equivalent manual c
