The Lens

by

Another important fact speaks in favor of a color video intercom – the active construction of residential and commercial facilities “premium” class in Russia, and especially in Moscow. Installed in front of the building, marbled or other expensive facing materials, vandal-resistant call panel icky kind – nonsense! Much more effective it will look beautiful outside panel of the clock with brass or an elegant bar with an exclusive blue backlit information display and call buttons. Such panels use color cameras with normal lenses rather than the lens type pin-hole, which has a much smaller aperture, and hence the lower sensitivity of the whole system. As for the price. I propose to compare two option. The first – an elementary system consisting of a calling panel and monitor, and a second, more complicated option for cottage village of 30 houses with an individual outside panel in front of each house and the digital outside panel to the common entrance to the village. For comparison, prices for video intercoms comelit (Italy): system.

Black and white version entryphone Comelit worth 14,800 rubles, a color – 22900 rubles. Price ratio – 1.55 to 1. Including work on the installation and mounting materials (approximately) the total cost will be 19,800 and 27,900 rubles, respectively. Price ratio – 1.41 to 1. The cottage village. System using a black and white video intercom will cost 583,000 rubles, nonferrous – 833,000 rubles. Value ratio – 1.43 to 1. Including work on the installation and mounting materials (orientirochno) the total cost will be 783,000 and 1,033,000 rubles, respectively. Value ratio – 1.32 to 1. As can be seen, the difference between color and black-and-white systems, including the cost of the installation and assembly of materials is 30-40%. What do we have for this money? In the first place – to increase the prestige of your home, apartment, office. Modern models video phone, meet the most demanding tastes of customers to design, elegant appearance and ease of use, designers developed the world’s leading manufacturers in the color video intercom performance. The second – increasing informativeness color image.

It may be objected that their family member or employee of you will recognize in black and white version of the system. This is true, but modern video intercoms systems involve the use of multiple calling panels and additional cctv cameras, working with one or more monitors. In this case, you can observe not only the person standing in front of outside panel of human, but also their surroundings, the entrances to the garage, playgrounds, etc. where the color of your car or clothing of man can be very important. Summarizing, we can conclude the following: Modern color video intercoms systems recommended for use in a modern office or residential complexes, where important on the one hand and design consistent with the overall style of the room, on the other – means the use of video intercom system, cctv cameras, additional calling panels. Black and white video intercoms are good for apartments or small offices as a budget option. We hope that this article was interesting and useful for you. It is now preparing the next article on the topic of security equipment and security – an article about DVRs and access control.

Yacht Construction

by

The poet Virgil in "Aeneid" Two thousand years ago celebrated the beauty of sailing ships. But people went sailing with an even more ancient times. Involved and the competition in figuring out whose boat is better. The modern sailing yacht, catamaran or trimaran multiple commission and beautiful sailing ships of the ancients. Construction of sailing ships of antiquity and modern yachts required and requires enormous skill.

Slavs of ancient Russia successfully built sailing ships and They floated on the Black and Caspian Seas. Black Sea, for this reason, the maps 15 th century was even called "Russian sea". From Peter the Great, his sailing yacht "St. Peter" is the beginning of sailing in Russia and the subsequent glorification of Russia as a great maritime power. After Peter's only a hundred years in 1846 to resume active yacht construction and the establishment of the Imperial Yacht Club in St. Petersburg. From this time on the current period Time has been a steady building of sailing ships. The modern sailing yacht, catamaran or a trimaran in its construction using traditional methods and advanced technology, trade secrets yahtostroiteley former times. And the fact that the traditions and skills of yacht is not lost, proving in particular in each of his masterpiece of modern company "Black Sea".

In particular, she noted that active measures for the protection of a threat to workers places and investment in Germany. Meanwhile, former German Federal Minister of Environmental Protection Klaus Toepfer refutes concerns that measures to protect the climate are a threat to the existence of jobs. He believes rejection of measures on climate protection in the eu is extremely shortsighted. Klaus Toepfer, said that climate protection can not be subject konyunkturno-political considerations. Russians continue to suffer from a bad environment According to Environment Centre 'Dodo', referring to the Committee for Hydrometeorology, more than 70% of Russian citizens breathe polluted air, the harmful substance which exceeds the maximum permissible concentration. The special issue was devoted to Volga region. Director of Environmental Center 'Dodo' Kayumov recalled that among the most pressing problems of the Volga, the deteriorating water quality, air pollution, increase the number of deaths from diseases provoked by environmental factors. According to him, in Russia, 50 thousand people die annually from diseases caused by bad ecology.

Including diseases of the gastrointestinal tract, kidney, liver, and allergies. He also noted that in the Volga region accounts for two thirds of Russian industry, so that environmental problems in this area are particularly relevant. Was awarded a prize for 'Best Environmental Project of the Year' on Thursday evening in Moscow were awarded honorary diplomas and special prize winners of 46 mep 'Best Environmental Project of the Year'. This award was established in 2008 by the Ministry of Natural Resources and Ecology of Russia to identify industrial, scientific and technical achievements in the field of nature protection and environmental safety.

Modern Finishing Buildings

by

Until recently in Russia, the most common type facades were handling their decorative plaster layer, the so-called “wet facade systems. But now the most promising technology finishes Facade is a system of ventilated facades with air gap. Construction of ventilated facades can effectively solve the problem of energy saving, and the presence of large amounts of material various colors and textures are used to run an external finishing layer, to significantly enhance the architectural merits of buildings. Applications: construction and renovation of residential, administrative, public and industrial buildings. You may wish to learn more. The fundamental difference of ventilated facades from other types of lining is the presence of air gap. Since in a ventilated air gap temperature slightly higher than the outside, the heat loss during the heating period are reduced. Due to the differential pressure, internal moisture is removed freely into the environment.

The main advantages of ventilated facades: Aluminum profile used in the fixture, not affected by corrosion and can withstand a fairly wide range of temperature fluctuations, is able to absorb the thermal strain arising from the diurnal and seasonal temperature drops, and hence the appearance of the building will not depend on the weather aluminum profiles are both durable and easy enough that facilitates and design, and installation of building insulation, used in systems of ventilated facades, allows water vapor from the room to enter freely in the air layer, preventing the formation and accumulation on the destructive designs of condensate they allow to give the building a beautiful view, thanks to a wide palette of colors finishing material ventilated facades, have excellent thermal protection: the wall is protected from the ac freezing and thawing, smooths fluctuations in temperature, which prevents the emergence of strains of unlimited possibilities of forming fronts in composite materials such as Alucobond, Alpolic, Reynobond can turn the most ambitious and unexpected projects architects ventilated facades substantially increase the longevity of the building as a whole, because they are resistant to freezing and getting wet – the two main factors affecting the aging buildings aluminum used in the systems of ventilated facades, is absolutely environmentally friendly, non-polluting and does not harm your health, but nowadays it is an important fact for Fire safety in the construction materials used, are fireproof or slow the undoubted merit of ventilated facades – insulation in the design is outside..
