We live in close proximity to this mysterious substance, and sometimes it does not even notice the dust …! Where does it come from? Did you know that at home you can find micro-particles of soil from the Rostov, tiny particles of sand of the desert Karakum, the ashes of the volcano erupting somewhere in Italy, and even dust from outer space? Every year on this planet are deposited tens of millions of tons of dust. Learn more about this with Michael Steinhardt. What is its origin? Scientists claim that about 70% of the dust has a natural origin, 30% is created by man. The most significant source of natural dust-soil. The particles are blown by the winds of the earth, rising high into the sky, are transferred to different distances and are deposited. There is still a dust ocean, When the sea air thrown in little crystals of salt. At the same time accumulate in the atmosphere of minute droplets of water. They are formed by breaking waves and rising waters from the bottom of the air bubbles.

Drops quickly dry, and air enriched with salts, crystals of which rise high into the air and hover in conjunction with water vapor in the form of clouds. Another source of dust, volcanoes and forest fires across the planet. For example, a Japanese volcano Sakurajima “rewards” of humanity 14 million tons of dust per year! Next to this volcano is the town of Kagoshima is the most dust in the world! Large “providers” are dust of the desert. Learn more at: Atmos Energy. For example, a huge Sahara sleep Russians, Britons, Australians and sand dust in the number of 60-200 million tonnes a year. Falls to the ground and cosmic dust, along with offering of meteor showers. In addition, there are pollens, spores, fungi, fur animals, rubber tire dust from the abrasive, fiber, natural and artificial fabrics … All this “cocktail” is always present in the air and gets into our house.

Our neighbors are also unpleasant dust mites. They are very small and live in house dust. In total there are about 50 species of dust mites. They feed on dead flakes of human skin. Many mites in pillows, bedding, upholstered furniture, in carpets, in the secluded reach for the vacuum cleaner … Scientists ‘please’ us such figures: the usual double bed home to about 2 million mites! By themselves, they can not harm humans, but their selection can cause allergies. Why dust accumulates indoors? The fact that none of the most thorough cleaning is not able to change the composition of air in the room. Dust settles permanently, respectively covered her furniture and floor. Even tightly closed windows and doors for dust do not pose special obstacles, so it is fine! It will penetrate any crack. The air inside the home is always more dusty than on the street because the streets are constantly blown by the winds.

Mobile (mobile) shelving, or "kompaktusy" – are essentially the same archival shelves, only mounted on a movable trolley that moves along rails mounted in the floor. With the help of easily movable shelving solve the problem of capacity, backing up to a small area. Mobile racks free to seventy percent of the warehouse due to the lack of passes between them. Compactness allows racks install them not only in stores, but also in offices and working locations. Carrying capacity is 60 kg, but if necessary can be increased to 150 kg.

This allows the use of mobile shelves and in warehouses. Structures can contain up to ten sections, and move from a manual drive. In general, mobile racks mounted with 2-6 sections, and mechanical drive. For safety reasons, electric use rare. Move through the racks of three types of handles: the wheel, which allows to move the design, not catching the handle, moving the handle lever and ratchet mechanism. The mechanism of movement is closed cover plate, and also come in three forms: with drive wheels on the transmission shaft, gearing sprocket wheels for chain and hand-outs to the transfer of the transmission shaft to the wheel.

Before mounting the movable shelving need to find bearing capacity of floors and ceilings, and, if necessary, install additional bearing beams. Made on the basis of shelf designs, mobile racks have a smaller weight, and located on the floor, parallel rails, promote equal distribution of weight. Shelf construction made of coated profile, the shelves are attached with bolts or special hooks. Grippers can be mounted movable shelving quickly and without the use of working tools. By design we can easily add more shelves. Easy to use movable shelving, the possibility of increase in the length or width, a wide range of additional elements (locking devices, sliding tables, dividers) – all this makes the essential mobile racks in your warehouse.

When sending and viewing video in real time are presented, as a rule, high demands on network bandwidth. For a rational distribution of traffic network video servers network support mechanism of QoS (Quality of Service), which allocates part of the channel in a streaming video of the STS-IPT480. Support for PPPoE (Point-to-Point Protocol over Ethernet) ensures minimal delay and high speed transmission of video and allows you to connect via network video servers ADSL-line or cable modem. Convert analog video signal up to 4 cameras to digital by a processor Arm9, built on the principle of SoC (System-On-a-Chip). Through this network video servers form a high-quality image and transmits it over the network in real time with up to 25 k / s as a quad image of four channels of CIF resolution, or as an image of a selected channel with a resolution up to 720X576 pixels. Thanks to the built-in web server, STS-IPT480 allows you to view digital video on the network through a standard Web browser, Internet Explorer 6.0 and above. Change the settings of the video server can only a user with administrator privileges.

User, not administrator rights, can only view the images in real time and to change the view settings. To connect to the LAN-and WAN-network network video servers are equipped with two network Smartec port 10/100BaseT Ethernet (RJ45). Analog cameras are connected to the STS-IPT480 four composite video inputs, and composite video output via a video server can connect to a monitor for viewing images. Audio Line In and Out devices allow you to organize a two-way audio with the video object. Special attention is paid to the STS-IPT480 protection against deliberate distortion of the video. To do this, network video servers use a technology called Digital Time Code, which exports to all the shots, "watermarks" in the form of the date and time. According to these signs, you can easily determine the exact date and time when the frame was received. In addition to protecting against counterfeit video, this technology helps in the analysis recorded alarm early material.

To work in the video surveillance network video servers are equipped with hardware motion detection and a connector for external alarm sensors. At receiving the alarm STS-IPT480 can send pre-and posttrevozhnye frames specified in the FTP-server, and also activate external alarm devices connected to its alarm outputs. In the supply network video servers STS-IPT480 equipped with Russian-language free software NVR, which supports the simultaneous viewing of "live" video with synchronized audio soundtrack as well as recording and playback of video and audio in MPEG-4. NVR supports all necessary recording modes: continuous, scheduled, motion detection or alarm. Pre-alarm recording the maximum duration of 30 seconds. New network video servers STS-IPT480 already arrived at the warehouse of the company "ARMO-Systems", which is the exclusive distributor of equipment Smartec in Russia and CIS countries, and you can buy them at a retail price of 820 USD, including VAT. For more information on video servers, please e-mail or call (495) 787-33-42 to sales manager. Under the brand name Smartec, a wide range of equipment to create classic and IP-video surveillance systems of any configuration. The product line includes black and white and color cameras, dome cameras, DVRs, IP-cameras, 4 -, 2 – and 1-channel network video servers, software, and widescreen monitors, a camera "day-night" device video transmission via fiber optic lines, brackets, housings, etc.
