Wireless technology in video surveillance systems. Part 1: The original Wi-Fi technology was used where there was no possibility of laying the cable. However, over time, wireless is becoming more spread not only in order to bring computers, but in video surveillance systems. Currently, the video surveillance market growing share IP video cameras, among which are a large number wireless solutions. That makes it easier to use the latest installation of video surveillance systems. However, the wireless solution has some nuances that leave their mark on this system.

First, it is worth noting that there are several standards of wireless networks. This so-called standards a, b, g, n. Each of them is supported by the maximum allowable speed of the connection: 11 Mbit / s, 54 Mbit / s and 300 Mbit / s, respectively. It is fair to say that the connection speed and actual speed are very different, and this difference is about 2 times. Thus, with increasing distance between Wi-Fi client and access point (or router) is reduced and the connection speed. These points should be considered at the design stage wireless video surveillance system. Based on the foregoing, we should also expect the configuration of your wireless network: the number of wireless devices and their configuration, the need to connect more with different antenna pattern and power. However, this will be a separate article later.

As for the standard Wi-Fi, then each new standard supports the previous ones. At the design stage it is important to choose and arrange equipment for wireless video surveillance as well as selected access point 802.11g standard is not allows you to take advantage of speed, which can give you a wireless IP camera standard 802.11n. Above I mentioned that depending on the speed wireless connection from a distance. Now bring some figures that will be useful. Standard 802.11b: indoors: 30m distance: 11 Mbit / s connection speed, 5 Mbit / s transmission speed, distance 91m: 1 Mb / s connection speed, 0.5 Mbit / s transfer rate, open space in the line of sight: 120m distance: 11 Mbit / s connection speed, 5 Mbit / s transmission speed, distance 460m: 1 Mb / s connection speed, 0.5 Mbit / s transfer rate. Standard 802.11g: indoors: 30m distance: 54 Mbit / s connection speed, 25 Mbit / s transmission speed, distance 91m: 1 Mb / s connection speed, 0.5 Mbit / s transfer rate, the open space in the line of sight: length 120 m: 54 Mbit / s connection speed, 25 Mbit / s speed, distance 460m: 1 Mb / s connection speed, 0.5 Mbit / s transfer rate.

Global Energy Demands

The global demands of energy had tripled since 1950 and must increase about 50% up to 2020, and the production of goods and services depends each time more than exhaustible and pollutant sources as fsseis fuels. bigger part of the world-wide consumption of energy is proceeding from fsseis fuels, main causers of the global heating and the effect greenhouse. The age of the oil will go to finish, not due to oil, but for the preservation of the civilization human being in a healthy planet, with the nature in balance? for the love or pain. It is not more possible to continue with the burning of enormous amounts of fsseis fuels, under gide of the economic growth. The economic growth unbalanced and different must be braked and to opt to social, economic and ambient the development sustainable. For reasons of energy security all the countries search power plants renewed, since the esteem reserves of oil last 40 years, of gas 60 years and coal 130 years.

It fits to the proper one human being to find alternative energy that must substitute the oil, and cleaner energy matrices are, despite slowly, being implemented in diverse countries, with the increasing use of sources you renewed. Plato said: ' ' the necessity is the mother of inveno' '. Brazil pose to be considered a model of visionary leadership in the growth process and sustainable development in its energy sector. Detainer of one of the cleaner energy matrices of the world, the country must assume a position of leadership in this new age of support, with local actions and global in favor of the expansion of the use of energies you renewed, by means of etanol and of biodiesel as commodities world-wide, produced of ambient and socially correct form, which is, without necessity of the deforestation, only with implantation of more efficient systems of management and development of tip technologies.

One is elaborations that can be taken to the work, to picnic, an excursion, to a rustic food, to eat in a trip, that is to say food to take.

It really is yet again not a chapter in the genealogy and. Mostly we come on the genealogy in the first place even to this question. As we have therefore collected some information about his ancestors and the further one goes back, in the table, the less clear is the person assigned. gave surnames / last names, it just still does not. They formed out only when more people lived in a settlement and therefore no distinction was made solely by the nickname. The origin of the name accompanying it is very different, and may be oriented to occupations, and appearances on behalf of the institution or place of origin. Most surnames originated independently several times.

A small example of an approach on how to explore the origins of his own family name, you can find on this, the name of vineyards dedicated website. Surnames can be derived from the profession, we know names such as blacksmith or miller, it may have been a property of the person, we know long or short, etc., also a place can be the starting point of a name. Of floodplain to Zwickau may have been named after places or just someone who lived by the pond, which was from the pond. If the name is very old, should be absolutely sure that we shall examine the language at the time of creation was widespread. Often you have to look up in Old High German, to find gold. Finally, it is advisable also to investigate the local origin of the name. This operation will then probably be already necessary to seek one or the other archive.

Finally is should be mentioned that a family name can be considered established if it is traceable at least three generations. Nevertheless, even a cessation of the name certainly occur, for example, if the name was not passed on by marriage. Who has become a curious kind, like to visit the above website. Have fun.

In short, there is still much work to do regarding the interaction betweeen Spanis and Indian launguages. In modern America and Central Europe the dominant language is Spanish, speakers of all Mesoamerican Indian languages include some who are bilingual: few languages are spoken by people completely bilingual, most indigenous languages are spoken by populations that can be that are at least 50% of monolingual speakers. All Mesoamerican languages with a significant number of bilingual speakers have been influenced by Spanish, primarily in areas of vocabulary, particles and word order. Since the conquest of Spain Mesoamerican languages have been borrowing words from Spanish, and since the type of Spanish spoken has changed somewhat over the years both in vocabulary and pronunciation, we can distinguish different historical periods in loan words. For a variety of reasons, certain function words like conjunctions or adverbs are often borrowed from Spanish: but since, until, and, or, nor, even, if, when, why, why, then. Some languages have assimilated the word order of subject-verb-object. Unlike the Spanish of Mesoamerica has been the recipient of vast amounts of lexical material in local languages, primarily the Nahuati, The loan has come from names of plants, animals, artifacts, and indigenous forms that were missing in Mesoamerica and Spanish. Among the reasons Nahuati has been the predominant source is that the Aztecs were the first Mesoamerican people conquered by the Spanish, the Aztecs had been in many parts of Mesoamerica, the Spanish recruited Aztecs, particularly as guides in their military forces to assist his quest to subdue the rest of Mesoamerica, and for several decades, Azteca, written spelling Roman was used in many parts of Mesoamerica to the official records of documents, wills and censuses.
