GSM Sensors
The operating principle of gsm signaling is that after firing any wireless motion sensor or door opening, and use a panic button activated a siren and immediately begin an alert via gsm channel by using sms (MMS) messages or phone calls to the owner or point guard. The user has the opportunity to record all messages, but with a special speaker to maintain direct feedback from the protected object. Consider some typical key system parameters GSM-alarm system. The first important parameter: gsm alarm system must be vandal, that is located in a secure metal case, where has all the elements, including – GSM-terminal block to connect cables, power supply. All this is necessary to perform the main functions of the system – the transfer of alarm sms or mms messages, and the inclusion of other devices. Well casing protects it from Snoopy.
The second option is that device must have no sufficient number of connectors for connecting various sensors signal. It is desirable that protected areas have been programmed – for example, the first connects to a chain of sensors movement, the second – the chain of Smoke detectors for the third – a reed switch on the front door, while the fourth – a chain of impact sensors. Also, do not interfere with some additional outputs for actuators (eg, light and reminders). The third parameter is characterized by the need to pay the availability and quality of the built-in power supply of special attention. After all, uninterruptible power supply and battery should provide a reliable the work of all elements of GSM-system (centralized and sensors connected to it) when a power failure for at least a day.
Night Vision LED
Lighting system in the photo and video cameras in the lighting systems, video surveillance is extremely important. Many of diffractive optical devices without additional lighting give a very low quality. A highlight in his turn may increase or decrease the characteristics of the observed objects. Low light object can even lead to a false image. All these problems can be avoided by careful application of additional lighting. When calculating the lighting systems are accepted parameters such photo and video cameras like: aperture optical system, the sensitivity of the camera, light spectrum, intensity, etc. Comparison of LED and conventional light sources.
A. Spectrum by the spectral composition of traditional halogen light sources like blackbody radiation. Efficiency of halogen lamps so low and declining due to optical components. Diodes also are semiconductor devices that convert electricity directly into light. The effectiveness of radiation in this case is very high, because radiation in the visible spectrum. B. Lifetime Hours Some ordinary light is less than 40 hours. Of course, the greater reliability of LEDs give the running time is greater than 100,000 hours, that is 11 years of continuous operation.
However, it is necessary to take temperature range devices. C. Mechanical stability of LEDs mechanically very stable. Because design of the diode consists of optical fibers by mechanical damage diode is out of work. Well, unless the hammer is not hitting. Such durability diodes allows their apply as light sources attached to any moving parts. But itself fiber not so mechanically staunchly. Therefore at blows and damages anyway is likely to reduce the light intensity. We offer a large selection of miniature video cameras, including camera with Night Vision LED-backlit display. Cameras in motion sensors and recording on an SD card. Wireless and wired models of street cameras and cameras for home use.
HDM Video
It is no good on the interaction of the amplifier and speaker systems, and in First of all much worse quality bass. Therefore, the transfer of audio signals into the second zone is usually a "low-current" form through a well-shielded interconnect cables. You can send and zvukodannye in amplified form – there are models with built-in volume control gain, but, again, the sound quality will be compromised. Already being actively used the system in which the audio signals are transmitted in digital as practically ne exposure to external interference. Of particular interest are wireless systems that use Wi-Fi-between Connecting to the central controller and receiver, transformative "figure of analog sound. But the most difficult question – to send the image into the second zone. Usually there is sent a simple composite video – the most noise-free, but less quality than the other types (S-Video, component, HDM1). Translation of long-range component of better analog or digital video signal is practiced infrequently.
Using the HDMI interface is hampered by the fact that it is very difficult and expensive to make long enough HDMI-cable without irreversible loss in image quality. Today the price of the connector can easily reach several tens of thousands of rubles, and the warranty – no … However, developers gradually overcome these problems by increasing the length of HDMI-conductors, has presented a workable model HDMI-cable length of 20 m. You can solve the problem by installing a special video amplifiers which increase the signal / noise ratio and thus immunity povyshayuschihtem line. It is true that such measures are relevant only when the funds videootobrazheniya require high picture quality. In most cases, play, say, television in the kitchen and enough "composite". Management of the second zone can be implemented in several ways. The most simple – lack of control, that is, all adjustments and settings performed in the base area one remote.
Selecting Original Gifts
Several times a year we are faced with a difficult problem – to choose a gift. It would seem that it may be easier, went to the Internet, found online gift shop, and saw your favorite thing and bought it, but ..

CCD Micro
Wireless mikrokamery applied in different fields of activity, performance covert video surveillance most frequent use of miniature cameras relaying pictures and sound over the air. Guard CCTV does not limit the scope of micro cameras, they often occur when using a cord model airplanes and helicopters as a pilot to maneuver the eye while on a remote control on takeoff field and also in avtomodelirovanii. Mini camera and a micro camera with radio data are essential to control the working process, as have the ability to simple reinstall to a new place without pulling wires than a help in the effective identification of unscrupulous employees. Through the introduction of new technologies into the device, the wireless cameras do not have previous errors in the work, the transfer is stable, and work in color range has become the norm on the market for wireless micro and mini cameras. Wireless cameras are easy to use and install, it does not need to understand enough to make no Forums cameras, namely, the whole system is analog and digital differing only in the way broadcast video signal from the CCD camera to a receiver device, the main advantage of digital systems is clearly an opportunity use in a single location for up to 4 wireless cameras simultaneously without the threat of imposition of the signal. Analog complex wireless micro camera enables the simultaneous use of only two wireless cameras more in 90% of the signals will be sanctioned and therefore strong interference in the reception of images, but with all the price of analog cameras up to 50% lower than digital. Its small micro camera is kind of desire install it in the form of a hidden camera, but we should not forget that such use is prohibited by law and set the 'hidden camera', you must notify the surrounding setting plates with an appropriate inscription. Range of your wireless mikrokamer can be increased by applying a radio signal amplifier for each channel, and selecting the best of the proposed work can translate the image on the 1,700 m.
Choosing Stairs
Already at the stage of designing the house to prepare and discuss options for the stairs, so that it was convenient and comfortable for all occupants. Production of stairs, is a laborious process that requires a certain dexterity and skill. Very often during the construction placed a temporary metal frame ladder, and then, without distinction, his attempt to sheathe the tree. But this problem is difficult to implement, and would be cheaper to order a one-piece wooden staircase. A large area of the house, allows you to put solid concrete staircase.
And in the future zadekorirovat it to your liking. If the space for a ladder is not enough, we can provide U-shaped or screw with a triangular steps. But we should remember that the angle for a ladder must be about 35-40 , the maximum angle should not exceed 45 . Matter of convenience stairs, this addition also a security issue. Therefore, the ladder must have fencing. The distance between the balusters should be between 150 mm and the height of fences shall be not less than 850 millimeters. Recommended step width for stairs is 250-300 mm. On the security setting is also a great influence provides material levels.
For example, if they are made of smooth polished stone, it is worth the additional lay carpet, and fix it with special holders. The classic material for the steps already long time, is wood and stone. Currently there and ceramic monolithic step for facing ladders. Of course, building a ladder, it is important to use high-quality and safe materials. Wooden steps, as should normally be glued from separate bars which are placed on special technology. Stone can be used only cut from blocks, as well as the produced explosive way, sooner or later manifest itself cracks. Choosing material for a ladder, you need to do working drawings and full specifications of all the details of which it is made. Materials for the manufacture of the following steps: the pillars at the beginning and end of each march between them should be charged, followed by the balusters, and behind them the stages already. If the staircase is composed entirely of wood, then began to produce "bowstring", that is the basis. Rigidity of construction fencing provide supporting columns, section 80-120 mm, and the handrail. Balusters mostly bear decorative fencing function. It is worth a lot of attention paid to color and the staircase, he usually gets to the color of windows, doors, etc. In Later, if he does not like it, the cost of replacement is approximately the amount of new stairs. Since the ladder will have to dismantle, wash off the paint, sanded, painted and mounted again. Proper use of ladders – is another important component in the selection. It is not necessary to install the stairs in a closed room, where nobody lives, humidity drops them down to 0% and, consequently, the tree dries out, and the stairs just come into disrepair.
Bluetooth GPS
The decision to buy a Nokia 6600 slide in the first place there for those who appreciate the stylish appearance, ease of use and wide range of functions. The new model phone from the Finnish manufacturer is surprising for its relatively small size – it fits comfortably in your palm.

For those who want to buy the Nokia 6600 slide, will be a welcome addition to the existing phone application Nokia Maps, which will not get lost even in the big city. You can use the features on Nokia Maps maximum, connecting via Bluetooth GPS-module together with a navigation license. Own internal memory of Nokia 6600 slide phone is small for this class – 'only' 18 MB, so comfortable listening to music (of course, the phone a built-in player and FM-radio – a mandatory standard for all new products) it is desirable to connect a memory card – microSD format is supported with up to 4 GB. The battery in the Nokia 6600 slide offers up to 4 hours talk time and 340 hours of expectations.
Agrotex
To shelter the seedlings and the establishment of greenhouses and hothouses are widely used plastic sheeting or Agrotex (also known as spanbond, lutrisilom, agrovoloknom). Everyone knows how to use plastic wrap to create teplichek and greenhouses. Transmit light, trapping heat. Beautiful! Widespread. My neighbor likes to grow early potatoes for themselves and family. At the same time on my comments says: "Its potatoes, she does not like purchase, it is delicious! "Try not to agree here J. Technology is as follows: In section pounces film that warms the earth in a week or two (depending on weather).
Meanwhile, somewhere in actively bins germinated potatoes. And here it is – day X. planted potatoes. And then comes the process that I can not afford – depending on the weather potatoes should then open, then close it. Need be watched! Do not open on time if the sun pripechet – a problem. Not close at night if frost – a problem. The problem with this is the same – we will not see the harvest. And if the rain, it is also a problem – a film heavy, presses potatoes.
Moroka so from film to drain the water carefully and not to damage the sprouts. But a neighbor did not take hard work, and he spared no effort and time grows early potatoes, and all he gets! From this, a rather standard procedure shows that film heats well, and the sun can overheat and our seedlings. But save us from the frost, but does not pass water.
Wheel Centering
All this would facilitate the task manager and significantly speed up the process of selecting windows for your home. Qualified specialist you pick up a window with a certain profile and glass, the most suitable to the conditions in your apartment, will advise the mechanisms of ventilation and locking mechanisms, the need for security window. If you pick up a box for a private house, not too lazy to take a picture in order to pick up the window, harmoniously combined with the appearance of the building. Once the window is matched to your door leaves zamerschik. Wheel Centering window – technically complex process that can produce only a qualified technician. So do not try to be measured independently. Especially because many large companies offer such free of charge service. 2.
Low-quality producer, the existence of marriage, poor-quality components. High demand for plastic windows led to the problem of entering the market of low-quality producers and suppliers. Violation of technology and marriage at the production stage can bring the future owner of the window a lot of problems: gapping and sagging shutters, breakage of parts fitting, and at worst, and cracks in the pane. To avoid problems, Choose a reliable manufacturer of plastic windows. Company's reliability can be determined by the following criteria: age of the company's image in the construction market, an office, professionalism, customer reviews. The level of security and reliability of the company you will be able to determine its advertising (rather large layout, skilful advertising copy, the presence of city telephone numbers and addresses of companies), by the presence of the office and its appearance (Company, on the market for many years have quite a large office, in contrast to the intermediary companies, or companies, one-day), literacy and professional employees (who have you advise on all issues, to give advice and tips.) Also one of the best criteria for selection are the recommendations of your friends who have already ordered the windows to the company and pleased with the result.
Acquire Planting Perennials
The cost of high-quality ornamental perennials are currently very expensive, so when you buy should carefully examine the goods. Modern flower market is rich in a wide variety of decorative cultures. The range of any shop of flowers and seeds appear occasionally perennial species of garden plants. That perennials do not require special care in comparison with the annuals, and can be quite a long time pleasing to the eye. Many crops are sold either in the spring or fall only, it depends on the biological characteristics of plant species, the cycle of vegetation – the conditions prevailing in their original habitats, and associated their period of dormancy. Sale of ornamental plants is associated with periods of planting or transplanting: for example, it is expedient to buy vesennetsvetuschie bulbs in autumn, when the vegetative mass completely died away, and the bulb is dormant. Dug out and got on the implementation of the bulbs already have rudimentary buds, from which the spring flowers are formed.
Exception to the rule are daffodils, buy and transplant that can be successfully even in the spring, when peduncles fragrance fragrant flowers. Of course, as in agricultural technology daffodils have their own characteristics and rules, but in general, ignorance of non-compliance is not so critical. Other crops go on sale in the spring – just in time required for timely planting in the soil. Thus, gladioli, krokosmii, lilies, daylilies and dahlias expedient to buy in the spring, when they successfully survived the winter, not withered and not picked up a bacterial rot, what can be learned, carefully considered the corms and tubers. Many of them already contain the rudiments of the young shoots – shoots, which showed a healthy development plants.
When buying perennials, it is important to be able to carefully consider the planting material for signs of trouble plants. What you should pay attention: whether in the tuber and bulbs of dark spots and depressions, bulbs and tubers must have a uniform color, be resilient to the touch but not dry and shriveled. If improperly stored in a dormant period, many bulbs lose turgor, are infected fungi when lightly pressed to not be released liquid. Vesennetsvetuschih bulbs are often sold in the shells – if the bulb was bad or was dried in inappropriate conditions of detention, it can be stained with the remnants of the soil, it is not permissible. The bulb must be clean, it should be reviewed in the growth zone – that was easy to determine where it Donets with roots, and hence will develop shoots. Often, scales bulbs hidden thrips – tiny that insects, which instantly ruin the whole plant material, and colors from it you will never live to see. Also listed in indoor or in an apartment, thrips can to attack and destroy all the plants. Do not hesitate to ask the seller to extract the package with a colorful label, to withdraw from there and planting material to consider. Do not hesitate to pick up the tubers and bulbs, or you might just lose money, buying a pig in a poke.
