Those who are accustomed to the water element, sooner or later begins to visit the idea of complete freedom – travel without a hired team. But to act independently in the sea, it is necessary to have an international certificate confirming your eligible. Otherwise, nobody will not release into the sea, whether you even own a luxurious ocean boat. It is recognized that the world's best training program developed by sailors in Royal Yachting Association – Royal Yachting Association. Her Headquartered in the county of Hampshire (England) and offices – around the world.

A document issued by that association is unconditional respect for all ports and marinas around the world. There is a more affordable way of learning yacht case – to apply to domestic sailing school. Today in Russia there are many such schools, but primarily it useful to find out if they have chosen the school license, motor boats, which documents it issues and who, actually recognizes. The fact that the Russian papers for the right to control the yacht practically not recognized anywhere except in his native homeland. And even the identity of yacht captain. Therefore, we recommend you immediately get Skipper certificates are recognized by rya.

Appropriate training can be, for example, in Turkey, Marmaris (yachting school Yuksel Turn Tech), where an experienced instructor will teach you the basics of sailing in just one week. The first step to serious yachting – Practical Course Competent Crew. The program includes the basics of marine affairs and "pilotage". After completing the course you can walk on a yacht steering or trained crew member. The second stage – a theoretical course Day Skipper Shorebased, supported by practical course Day Skipper Practical. The program – the basis of ship management, introduction to navigation and meteorology, the device and sail. Practiced in the future skippers at sea under the guidance of instructors and receive an international certificate that allows them to go to skipper in the coastal waters and their own charter boat. On the higher skill certificate indicates Coastal Skipper, allowing to sail at any time and in any direction. Yachtmaster – the highest stage, which gives unlimited rights as a yachtsman on the part of the authorized management of the vessel, and geography of navigation: you can safely cross the ocean!

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.
