The rise of cottage construction pulled the loop of new problems. One of which is the protection of property and secure accommodation in the country house
For the last 2-3 years, the number of home theft has increased dramatically. Inesley before they occurred, as a rule, in the absence of owners, now there are often invasion cases and sleeping residents. What explains the increased self-confidence of attackers? First, the tendency of homeowners to inappropriate savings (save not on what follows), secondly, the most ordinary carelessness (according to the type "What do we have to build a house? Let's draw, we will live!").
Usually, the development of the site begins with the appeal of its owners to the architect and landscape designer. What are the customers and architects, including the most experienced, think last? Alas, about security. Often, people do not even imagine how it should be provided. AVEDE security of accommodation is not limited to protection against fires, robbery and other criminal actions. It is necessary to achieve environmental safety, as well as a whole system for ensuring comfort. Plot and house with good architecture should not have ugly engineering systems. Agree, the surveillance chamber, fixed on the lamppost in the style of the XIXVEK, will destroy the artistic image of the landscape. How to link the aesthetic tasks with technical, not received neither by those nor others? Probably, you should start with the study of the features of each of them. Let's start with engineering tasks.
A high-quality security system can be created only with the participation of the customer who will determine the circle of its wishes, and firms in the face of engineers, designers, architect and designer. Plus, it is desirable to cooperate with private or government security structures.
The currently used cottage protection systems can be divided into perimeter, intercom, alarm systems for the home, video surveillance system and group security systems.
Border is locked tight
The presence of a security alarm inside the building does not always guarantee its inhabitants complete safety. After all, the criminal is detected only at the moment of penetration into the house, and then the events can develop on any scenario, and not always the victory goes to the owner. In addition, the attacker has the opportunity to inspect the house from the side in advance and take into account when all its features penetrate. So more intelligently initially ensure the protection of the boundaries of the site. In this case, the possibility of early warning about the invasion of an unauthorized person will appear in your possessions. After all, the violator must first overcome the fence. To date, the perimeter protection (PSO) market is filled with a variety of devices: radiole, capacitive, vibration, infrared (IR). Requirements to all of them are quite strict. Devices must: detect the violator on the farthest approaches to the house; Do not have "dead" zones with any area relief; Being imperceptible and immune to weather conditions (temperature, precipitation, humidity, etc.), as well as resistant to industrial electromagnetic fields.Radiolochy PSOs Based on the basis of one or more microwave detectors, each of which consists of a receiver and transmitter. Between them is formed by invisible radar, the hit in its zone causes an alarm. But systems need "pure" borders. For sections with a length from 5 to 130m, the RLD94FR ("Security Technique" detector) is suitable. It is performed in the form of a garden lamp and indispensable when protected areas with increased landscape aesthetics requirements. It can be located on a telescopic rack, as well as on the fence or on the wall of the house. It's not afraid of rain, no frost, no heat.
In the sections of up to 500m, the radar detectors "Barrier-500" ("security technique") have proven well. The device is able to detect the intruder moving along the protected area (the rapid growth or bent). A volume electromagnetic field is formed between the transmitter and the detector receiver. The detector feels the change in this field in the event of an invasion of the violator and sends the alarm message to the control panel (residents). The detector detection zone is very impressive: a length of 10 to 500m, 1.9 m height and 6m width. The cost of the device without installation- $ 510. Installation is performed in a very short time, without harmable for landscape design.
Vibrating PSOs Trim from concussion. In general, one of the first PSOs was the vibration system Psicon (United Kingdom) reacting to the vibration of the soil. It is installed as follows. The imbrees depth to 0.7m and 0.2-0.4 m wide laid cable with seismic sensors. The cable passes through the zone of the intended penetration. The Psicon system reliably detects even gently walking or crawling man, not to mention the violator that jumps from the fence.
GEOQUIP (United Kingdom) provides a number of developments to protect the perimeter of the site based on sensory microphone cables. One of which is the electronic guard system Guardwire. It is mounted on light fencing (metal grid, wooden fence). The principle of operation is based on the use of the microphone effect in the sensor cable, which is attached to the fence and registers its mechanical oscillations when attempts to invade the object. The sensor cable is a distributed electromagnetic microphone. Contains two fixed and two movable conductions located in the gap between two flexible magnetic strips of a semicircular cross section. The core core is covered with an insulating layer and is apparent. Outside, the sensor cable is protected by a solid polyethylene sheath. Looks like an ordinary wiring and does not cause any suspicion at an attacker.
The sensor signals are processed by an analyzer, which, suspecting a real impairment attempt, includes an alarm. The cost of the system with the installation is determined at the rate of: 1 run of the fence - from $ 13.
Raewy IR detectors Consist from an IR emitter and an IR receiver located in the zone of mutual visibility. The alarm occurs when the beam passing between them is interrupted. A distinctive feature of these devices is a very narrow detection zone (3-6cm). Animals and large bird alarms are not called. Radiation IR detectors are designed to control the rectilinear areas of the protected area. The maximum length of the beam detection is 210-400m. The system can be installed at the top of the fence or directly on the ground. Orthh (Japan), Visonik (Israel) and others offer a wide range of models for installation both inside and outside buildings. This equipment rarely causes a false alarm, but relatively expensive- $ 90-600.
Control panels
This is the brain center of the security system. The panel receives signals from sensors (detectors) and gives the necessary commands to executive devices, such as sirens, spotlights, locks, telephone, etc. All actions are manufactured in accordance with the program that the owner asked. The panel may contain a keyboard with which commands are specified, the locks are encoded, or the scoreboard (display) to indicate the place and type of violation.
As an example, we give the Powermax panel of VISONIK. It is compatible with the "smart" home control system and supports security and fire alarm functions. Powermax is capable of controlling any devices connected to the 220V network. Does not require additional wiring for sensors, since the latter are connected to it by radio channel. At the same time, the frequency of radio waves is not affected by the system of civil and military communications. On the plot and in the house can be positioned to 30 for the sensors. The panel responds to the radio signal signals, which can be given seriously ill or disabled, so that it controls the housing, and if necessary, caused help on the phone with one pressing the button. Two speech messages can be stored to vumerati (for example, any reminder to children when they came from school). Another useful feature of this mobile communication support. You can listen on your mobile phone what happens in your absence in the house. PowerMax is produced fully Russified and adapted to our conditions. The cost of the basic set is about $ 400.
In the near approaches
Intercom is the most comfortable, "home" part of the security system. It is designed not so much to protect the owner of the cottage from unpleasant situations, but to ensure it convenient and harmless communication with the outside world. It consists of external and internal blocks connected by wires or radio channels. The outer block (call panel) is mounted outside the front door or wicket. It has a call button, a negotiation device and a miniature wide-ancode video camera. Extremely models have an IR-backlight unit to see the visitor in the dark. The part of the intercom, mounted inside the dwelling, includes a negotiation device (tube), a built-in mini monitor and a button for unlocking a power to the inlet door. Usually the camera installed in the call panel shows only what is directly in front of the door or gate. It is enough for an attacker to move away to the meter aside or cling to the wall-willow will not see it.In this case, an additional street mini-video camera can be attracted to the rescue, installing it is secretive not far from the entrance. The Japanese company AIPHONE releases intercoms with a built-in rotary mini-chamber to increase the viewing field vertically before entering. Very useful in the life of the model with a memory block. This is the help of an intercom (for example, MJS-1AD from AIPhone, $ 800) remembers several dozen images from the call panel. Returning home, you can quickly view the images of those people who came throughout the day, but did not find you at home. There are models that combine the intercom with a regular phone and a TV (for example, WJ-350 from Daytek, Y.Koreore). If the visitor call interrupted your conversation on the phone or viewing a telecast, the device will automatically display a guest image on the screen, will give a signal without interrupting the telephone and return to a call or television mode.
South Korean firms Commax, Vortec, Kocom, Italian Urmet and others offer various models of internal monitors, call panels and mini-chambers, as well as additional handsets, sensors, locks, latches. Places of installation of tubes and monitors depend on style and rhythm of your life. Usually they are installed in the hallway, near the staircases (on each floor) and in other rooms (sweat, in the kitchen, etc., everything is individually). The cost of prestigious intercom equipment- $ 300-850. Duty costs reach $ 1000-1500.
On the second turn
Weak places through which the attacker can penetrate inside your fortress, quite a few. First of all, these are windows and doors. On the upper floors and attic criminals are easily climbing along the withdrawal stairs and close to growing trees. Frequently used basements or unlocking houses (boiler room, garage, shed, etc.). All these points must be revealed before the arrival of the "enemy" and protect.
The system of protection of the house (more precisely, its elements) includes a variety of detectors (detectors). There are sensors (as a rule, a lot and not necessarily one type) and a control panel. There are disclosure detectors of the window, hatch, protective lattice or doors, detectors of the integrity of glasses, roofs or walls, motion detectors. Various physical laws and phenomena are applied to the descriptive of their sensors. Many PSOs discussed above are suitable for installation inside the house.
But more often to protect against indoor penetration, designed specifically for this system and instruments are used. Such devices are distinguished by small size and can be installed secret. According to the principle of operation, they are very diverse. For example, about two dozen detectors of the magnetocontact, shock-contact and vibration types for the protection of windows and doors offers the enterprise "Magno-Contact" (Mr. Razan). The DIMK detector is interesting, working as on strikes and on the change in the angle of inclination of the structure. It will give an alarm not only when they break the glass, but and when it takes out the entire window, not breaking. A number of infrared and radio-wave devices for detecting criminals inside the premises manufactures ARGUS SPEKTR (SANCT-PETERSBURG).
When you select the device, it is useful to clarify the area of its action so as not to leave strain in defense. In addition, it is important to know how the device reacts to the movements of domestic animals. The spectrum of security detectors on the market today is so wide that you can always choose the device you need.

CCTV
To monitor the site and house, the owners of country houses are increasingly resorting to the help of street video surveillance systems. Depending on the parameters of the selected equipment, you can see how many people approaching the building (the cheapest version), distinguish their faces and even the number of the approaching car.The video surveillance system as basic elements includes one or more street video cameras and monitor. If you need to observe on one monitor or record images from many cameras on one recorder, a switch, a quadrator, a multiplexer and a special self-magnetophone applied.
And yet the main element of the system is a video camera. Usually, black and white image cameras are used for video surveillance. They have a high sensitivity in the infrared area of the world, and therefore they work successfully even at dusk, and at night, the Illuminated IR projectors help them. Color cameras are rarely used because of their high costs.
When choosing a lens for the camera, you need to answer three questions: What territory you need to view how small images do you need to distinguish and how to compensate for the lighting changes? These problems the customer decides together with the engineer of the company. An extremely important characteristic of the camcorder is the viewing angle. Inexperienced user often believes that the corner is wider, the better. But the wider angle, the less parsing the viewing zone and the observed object. Therefore, you should choose the minimum necessary overview angle for tracking the designated territory. Advocacy conditions (due to the changing light) it is better to use lenses with an automatic adjustable diaphragm. Cameras with such lenses are more expensive, but it will be much easier to observe and increase its quality. The price of the lens without a diaphragm is $ 30-100, with an automatic diaphragm - $ 70-400.
Externally, the chambers can be very different, but it makes sense to pay attention to those of them, which are made in the form of a dome with a transparent or smoky flange. Built-in IR illumination provides a clean image in absolute darkness. The darkened glass interferes to determine the chamber tracking area. Unobtrusive appearance makes the device imperceptible both on the site and in the interior. The camera is attached to the wall, ceiling or on the post. Often such a device is taken for a regular lantern. The cost of dome chambers is $ 1500 and higher.
The number of cameras mounted on the site depends on its area, visual observation zones and functionality of the chambers. Usually one camera is focused on the main entrance. It allows you to monitor the movement of people and cars outside the site, on the site in front of the house. Corner cameras installed around the cottage provide an overview of all approaches to it. Finally, the cameras installed on the fence record the moment of approaching anyone to the territory, as well as overcoming the attacker of the fence and movement along the site. In addition to the security task, the video surveillance system can play the role of a nanny, tracking the location of your children and demonstrating you what they do. For these purposes, the chamber is mounted near the water branch or playground.
Equipment of video surveillance systems can be divided into inexpensive from Southeast Asia and CIS countries and expensive from Western Europe and America.

Hermokozhuhi
The camera installed on the street is usually in a special guerofer. Her lens looks through a special durable glass. Casing serve to protect the sensitive device from temperature differences, dust, precipitation and other harmful factors, as well as from vandalism acts. They are made by all-metal or from high-durable plastic. The all-metal casing with a solid 12-millimeter window from the plexiglass for a long time can successfully confront the attack of the criminal.The climatic conditions of our country are presented to protective covers high demands. Most firms producing these products establish special heaters with a thermostat. For heat sink at high temperatures, a fan is provided. This makes it possible to ensure the performance of the chamber at temperatures from -40 to + 50c. Some manufacturers produce cameras in a purely street performance. The books include Russian MVK cameras. They are well withstanding our climate and provide tolerable characteristics at a low price.
The cost of the hirmels varies from $ 50 to $ 450 (the price depends on the additional configuration of the heating device, the anti-vandal design of the casing and its common dimensions). For fastening camcorders use various types of brackets: vertical, angular, telescopic. They provide for a cable pass inside the tubes, it allows you to hide the wiring from the camera. The cost of brackets is $ 20-350, depending on their complexity.
Monitor
Security systems monitors serve to view the image obtained from the camcorder. To view images from several cameras simultaneously use monitors with a screen diagonal from 14 "to 21". Smaller screens sizes (5-12 ") are used if there is less than three cameras in the surveillance system. In order not to suffer image quality, the resolution of the monitor should be high enough (one and a half times more than the camcorder, but not less than 400The). Monitors are available in a solid plastic or metal case. The built-in compact loudspeaker provides high-quality anxiety signals and listening to the observed area (subject to the installation of microphones in the locations of the camcorder). These products are about $ 500-850. Colored monitors, naturally, more expensive black and white.

Sweetchers, Squares and Multiplexers
If in the system numbering several cameras, it is supposed to observe objects only on one monitor, a video ammumber is used, which is more commonly called the Sweatcher's incomprehensible word. It allows you to view pictures from all cameras, but only sequentially (scrolling). Switching from the camera to the chamber can be both manual and automatic, depending on the model. Imaging there is a significant drawback. Each time it allows you to watch on the monitor or record an image from one camera only on the VCR. The rest at this time are not available for the operator. If there are more than four cameras in the system, the delay between the viewing areas of the observation can be about a minute. The aruto is already fraught with a "hole on the border." Some manufacturers (Samsung, Hi-Sharp) are embedded in the monitor. This equipment is most often offered separately from the rest of the video system equipment.The square divides the monitor screen into four parts and allows you to view pictures from four cameras at once. In a combination and in what sequence to have images, solves the operator. The device can be switched to the VCR and write four pictures at once in one frame, but their clarity will be bad. Cheap Squares come to Russia from Taiwan and South Korea. Expensive technique produced Gyyr (USA), Bischke (Germany). The price of black and white squares- $ 300-1350, color- up to $ 3000.
The multiplexer is necessary for high-quality recording on a special videosagnetophone of images from several cameras (up to16). It can display a multiferic monitor screen composed of images from any combination of cameras. It is convenient to view the previously made record. At the same time, you can display a record from one camera, ignoring all the others, while information from other cameras continues to be recorded and in the case of the receipt of the alarm information will be promptly displayed on the screen. Moreover, the device is equipped with a built-in video movement. The latter tracks the characteristics of the image in individual, pre-selected (marker) points of the fixed picture. Watching any changes to the picture is automatically displayed on the monitor and recorded. At the same time, the date, time and number of the alarm zone are recorded, and the operator is sent to the alert signal (sound or light). Such an observation technology saves a place on the film, helps to quickly detect an object of observation and take appropriate security measures. There are devices for black and white monitors on average $ 600.
SpecialtyMagnetophone
SpecialtyMagnetophone is designed to record continuously for a long time (from3 hours up to 40 stems). In the case of interruptions in power from the network, a lithium battery is built into it, which allows you to save all the tape recorders for 30 days. Image recording on a special VCR allows you to detect preparations for criminal promotions at an early stage. More or less serious criminal encroachment is preparing in advance, so if you see that unfamiliar people or cars often appear before your site, this is an occasion to appeal for help in law enforcement agencies.
In case of disappearing a video card or receipt of information from the motion detector, an alarm is fed. In this case, the VCR goes into a three-hour recording mode and records what is happening in detail. Daily specialtymagnetophones are used to 30 different functions. Special video tapes are applied for high-quality recording and playback (cost up to $ 20). Hitachi, Sanyo, Mitsubishi (Japan), Samsung (Y.Koreore) and others offer a large selection of video recordings at a price of $ 470 to $ 1,200.
Piece game
Type of equipment and its number are determined by what and how you want to guard. The cost of the simplest video surveillance system (stakes installation) consisting of one chamber connected to the TV and home video recorder - from $ 1300. Image quality on the screen will not be the best. When playing, many shooting details will be fuzzy. By purchasing a system with a monitor, but without a special special videos, on average for $ 1700, you will receive a high-quality picture on the screen, but the record will not improve. According to experts, the minimum set of a security system with installation costs about $ 2200-2500.The cost of the "turnkey" security systems when contacting firms selling and installing security equipment takes up to $ 14,000. This amount is determined by the quality of the equipment, the features of the object and the amount of security measures.
The last frontier guard is the protection of the cottage from the fire, gas leakage and flooding. But this is the topic for a separate detailed conversation.
