The invention relates to the field of security alarm system, in particular to the means of surveillance designed to detect and identify the offender, penetrating through the detection area of long security line and causing actuation means of detection.

Well-known methods of surveillance of the protected area, which are traditionally used video cameras located in places (points) monitoring and transmitting video information over a communication line to the Central control operator. The received video information is continuously displayed on the monitor screen and recorded in the device backup. To view video from multiple cameras are used multiple monitors or a single monitor with the possibility of switching (multiplexing) video images from different cameras. As routes of communication typically use coaxial cables with transmission of a video signal in analog form or wired communication line during the transmission of video information in digital form using communication interfaces (e.g. Ethernet).

With a large number of video cameras installed on the long (up to 60 km or more) objects of protection, such as the borders of the State border of the Russian Federation or pipelines, traditional methods of surveillance hundred is Owada unacceptable because of the complexity, large volume and high cost of the equipment used and cable lines, and also because of the routine work of the operators, on which lie a great work on detection and identification of the offender in a huge array of video information. The functional reliability of such systems to detect and identify the offender unacceptably low. Functional reliability is improved by using the principle of malosadovaja surveillance. Allocative TV (or system slow scan) is used with 80-ies in the space industry. The essence malosadovaja television is that the captured video frame is stored in buffer and then passed to the slow speed at the point of reception, while maintaining good image quality (i.e., the performance is considerably inferior in favor of image quality). To increase the transfer rate in malacatoya systems use compression algorithms that allow for the transfer of the image areas with the change of subject with high resolution, and other parts of the image (without changing the plot) is low.

Advantage malacatoya video surveillance systems is that they can transmit video via communication cables of any type with a bandwidth of 3 kHz (instead of 4.2 MHz is required when transmitting in real time). Transfer floor is on one video frame in the band of 3 kHz occurs at the time 1-72 C. But if necessary, for example the "Alarm"signal, the frame rate can be increased to several images per second.

Overall, a significant disadvantage of known systems surveillance is the lack of functional reliability of systems for the detection and accurate identification of the offender in the long borders. In addition, the well-known CCTV system and control long lines of protection are complicated in design and expensive. Such systems include, for example, a known system of Electronic security and surveillance system described in US patent No. 4511886, IPC G08B 1/08, H04N 7/18, publ. 1985 and contains the group of cameras and motion detectors, a group of microphones and a preliminary group of audio amplifiers, the group alarm sensors, switch (switcher), the transfer unit of the spectrum (interface unit transmitter), which consists of block compression (video compresser) and the buffer coaxial cable as the communication line, the Central monitoring station (Central control unit) and other elements. This security system and video surveillance provides connection to many remote video cameras to a Central monitoring station (Central control unit) through the transfer of information via a coaxial cable. The principle of converting a video signal for transmission is vortices, compression and transfer spectrum in the high frequency range, followed by sealing the channels for transmission over a coaxial cable. For channel selection time switch is used, which is in the standby mode can mount the camera at the request of the operator or in the foreground to mount the camera at the occurrence of the signal from an external sensor (e.g. sensor alarm).

Given the possibility of connection to the Central control unit in the system of a large number of remote video cameras, the system has a finite bandwidth. The presence in the system buffer (volume 197 kV memory) allows for a slow scanning speed in standby mode (update on the Central control unit every 4 seconds) and fast scanning speed (update after 0, 2) in the alarm mode.

Similar significant features of the declared and the above system are: Central control unit and the remote from him camcorders, compressor unit, the buffer inputs from external sensors.

Known system Addressable security monitoring system described in US patent No. 6646675, IPC H04N 7/18, G06K 9/00, G08B 29/00, publ. 2003 and comprising: a Central control unit and a group of addressable video cameras connected to the Central control unit via a single coaxial cable. This safety control system with addressable ability allows you to associate multiple cameras with a Central control unit located in the pun is the protection, using a single coaxial cable. To connect specific camcorder Central control unit sends cable address signal that is perceived by all cameras. Camcorder demodulator address signal and the video camera, in which the addresses are the same, and connects the signal to the coaxial cable, which is transmitted to the Central control unit and reproduced by the security guard. Using this principle in the system can be made cyclic polling of all the cameras at the request of the operator.

Similar significant features of the declared and the above-mentioned systems are a group of addressable video cameras and a Central control unit.

The disadvantage of the system is not at a signal from the actuation sensor (alarm) video frames corresponding to predriving, anxious and positioni situation in the field of view of the camera. Another disadvantage is the use of coaxial cable, which extended the borders considerably increases the cost of the surveillance system and control.

A known system for High-speed digital video serial link as described in US patent No. 6084631, IPC H04N 5/232, publ. 2000, and contains a group of remote video cameras, switching unit (HUB), the main processor (Central control unit), the switchboard is operating the communication line, connecting the switching unit to the main processor. This system provides video control of local areas of the territory and control of remote cameras in real time by using a bidirectional digital serial communication. The system provides information in two different protocols: one for video, another for switching and control. Through the use of digital transmission of information in the system is reduced requirements for bandwidth, which allows the use of simpler and cheaper communication cables. The switching of the communication line can be performed preferably two twisted pairs of wires. Alternatively can be used in fiber-optic communication line or channel.

Similar essential characteristics are: a group of remote video cameras, switching unit (local unit), the Central control unit (main CPU), switching of the communication line (channel switching).

The disadvantage of this system is the possibility of losing important disturbing video when switching cameras with one another or the quick change of the videos due to the lack of buffering (storing) image frames in video cameras, which makes it difficult or unacceptable detailed view of the alarming situation with the purpose of the reliable identification of the offender. Another disadvantage of the system is not at a signal from the actuation sensor (alarm) video frames corresponding to predriving, anxious and positioni situation in the field of view of the camera.

Known "Method of multi-channel video surveillance and implements his system (options)described in patent RU No. 2250503, IPC G08B 25/08, G08B 13/196, 04N 7/18, publ. 2005 System that implements this method, contains blocks of video surveillance with camera and microphone, cable transmitter, a cable TV line, the imaging system and/or write unit summation N videoarticles in one comprehensive videoaudiovisual. This system enables the transfer of images and sound in real time from multiple cameras through a single cable (coaxial cable) by summing a group of spectra television signals and transferring the received spectrum in the high frequency region. The system provides simultaneous display of video images from surveillance cameras, and selective display by the operator with one of the cameras. In particular, this system is designed for multi-channel video surveillance passenger train consisting of 12 cars (4 cameras on the wagon), with whom animowane in the range of 1-15 seconds.

Similar significant features are: cameras, cable railway, the visualization system and/or write (Central control unit).

The disadvantage of this system is the possibility of losing important disturbing video when switching cameras with one another or the quick change of the videos due to the lack of buffering (storing) image frames in video cameras, which makes it difficult or unacceptable detailed view of the alarming situation to ensure a reliable identification of the offender. The disadvantage of the system is the lack of opportunities to register for signal actuation sensor (alarm) video frames corresponding to predriving, anxious and positioni situation in the field of view of the camera. It should be noted that when a large number of video cameras is the sum of the group of spectra television signals degrades the image quality, making it difficult to identify the offender. In addition, this system becomes unacceptable for video surveillance and monitoring, extended the borders (for example, for the protection of the state Border of the Russian Federation with areas of up to 60 km) because of the significant cost coaxial communication lines (cable television line).

The mentioned disadvantages are partially eliminated in the other closest in technical with whom snasti to the claimed invention, the known device "Pre-alarm video buffer"described in US patent No. 2008/0198268, IPC H04N 7/18, publ. 2008, the Device comprises a video camera (or video server), which includes the interface unit (data network interface), the image matrix with the optical window and the lens (analog camera), the digitizer (A/D converter), video controller video controller, block compression engine), the buffer is designed to save predriving image frames (pre-alarm buffer), the CPU (processor), memory (memory), input for external sensor (detector), the block Association (combiner) and the channel switching LAN/Internet).

This device provides buffering of the video. Used in the device, the method allows to obtain input structure image frames from the input video stream, including the overall structure of the image and the distinctive patterns of the image. The product uses a compression algorithm for video sequences (e.g., MPEG-4), according to which some full structure of the image are replaced with the distinctive structures of the image that contain the differences between the previous full image structure and replaced by a structure. Thus in the buffer can be stored instead of the full video only differences between the existing and the previous structure, which ensures slimming the volume of the buffer. The use of buffer in combination with block compression allows the signal from the external sensor to identify predriving and positionnow the video sequence and to transmit them to the Central control unit via an interface unit through channel switching. Proposed device, the method allows to pass from 10 to 300 frames disturbing video from a speed of 10 frames per second, which corresponds to from 1 to 30 with observation time of an alarm event.

In standby mode, the data output from the analog camera enters the digitizer and then to the input of the controller, which converts the video signals into video. The compressor unit compresses frames of video in the MPEG-4 format and transmits them to the input of the interface unit, which in turn sends them to the Central control unit on the channel switching.

When it detects an intruder, the signal from the external sensor, the processor sends commands to the display controller and the buffer, for which the overall structure of the image and video and compressed patterns image from the compressor unit are received in the buffer.

Petralona sequence is formed by the combiner, in which the overall structure of the image combined with distinctive structures and then transferred through the interface unit according to the channel switching unit is ontrol. After the transmission is completed predriving video positiona information is transmitted in the normal (standby) mode. Thus, Petralona and positiona the video signal from the external sensor is sent to the operator at the Central control unit automatically. In the device there is also the possibility to initialize the process of forming predriving and positioni information in the analysis of video images using a motion detector, which is implemented by software in the processor (the program stored in the storage device). All the processes occurring in the device, are performed under control of a computer program that is stored in the storage device.

Common essential characteristics of the claimed solution are: a video camera containing the interface unit, the image matrix with the optical window and the lens (analog camera), the output of which is connected to the digitizer, the output of which is connected to the first input of the controller, the output of which through the compressor unit connected to the first input buffer, designed to save predriving image frames, the second input is connected to the first input of the processor, the first input/output which is connected to the input/output controller, the second input/output about what essor connected to the input/output storage devices the input processor is the entrance video camera for external sensor, the output interface unit connected to the channel switching.

The disadvantage of this device is (due to a one-way interface) lack of control by the operator of the Central control unit of the number of frames predriving, anxious and positioni information, as well as the refresh rate of the video image (the number of frames per second) and the total time of the video for a detailed view of the alarming situation with good image quality to ensure a reliable identification of the offender.

The disadvantage of this device is the inability operation mode day/night backlit viewing camera at night with IR illuminator, and lack of adisoemarto cameras, which eliminates the possibility of increasing the number of cameras for surveillance and control of extended borders.

The aim of the present invention is to increase functional reliability.

To achieve this goal in the known technical solution is introduced significant new features, functional elements and relationships that allows, first, to improve functional reliability by improving the quality of a received video predriving, anxious and Positivo the second video data, formed on the signal from the external sensor, and to get a detailed view of the alarming situation to ensure a reliable identification of the offender, secondly, to increase the functional reliability due to persistent surveillance using day/night and, thirdly, to reduce material costs for the creation of a system, and in General to expand the scope of the system for protection of local areas, areas, restricted areas of control, and extended the borders, such as the State border of the Russian Federation, pipelines, Railways, etc.

Secondly, increasing the functional reliability is achieved in the proposed second variant malokakhovka CCTV system to monitor the long lines of protection, which in addition to the first embodiment of the system for the operation mode day/night inside the camera introduced a second lens, optical filter, the second image matrix, the switch signal and the IR projector, the output of the second matrix of the image connected to Stromovka switch video the third input of which is connected to the second processor output, the third output of which is connected to the input of the IR illuminator.

Thirdly, increasing the functional reliability and the expansion of the scope of the system achieved in the proposed third option malokakhovka CCTV system to monitor the long lines of protection, which in addition to the first or second options to the channel switching is connected group of addressable cameras (total m)installed on other local areas of long security line. Channel switching is executed in the form of transmission of information by wire, optical fiber or radio through bilateral serial communication interface.

Fourthly, increasing the functional reliability and the expansion of the scope of the system achieved in the proposed fourth embodiment malokakhovka CCTV system to monitor the long lines of protection, which advanced to the third option is entered n of additional groups of addressable video cameras, connected to the corresponding switching channels, which are connected in turn through the respective blocks, the local to the Central control unit.

The invention is illustrated figure 1-5, which depicts the following :

Figure 1 shows the structural with the EMA malokakhovka CCTV system to monitor the long lines of protection, where we have introduced the notation: video - 1, channel switching - 2, Central control unit - 3, the video camera includes: an optical window 4, the first lens 5, the first image matrix - 6, the digitizer - 7, video - 8, the compressor unit 9, the buffer 10, the interface unit 11, processor 12, a storage device 13, an input for an external sensor 14. Figure 2 shows the structural scheme malokakhovka CCTV system to monitor the long lines of protection, consisting of video cameras with features day/night - 15, channel switching - 2 and the Central control unit - 3. The composition of each camera day/night 15 includes: an optical window 4, the first lens 5, the first image matrix - 6, the digitizer - 7, video - 8, the compressor unit 9, the buffer 10, the interface unit 11, processor 12, a storage device 13, an input for an external sensor 14, the second lens 16, an optical filter 17, a second matrix of image - 18, the switch of the video - 19, IR-floodlight - 20.

Figure 3 shows the structural scheme malokakhovka CCTV system to monitor the long lines of protection with the decomposition of the system into groups of local areas (zones) with addressable video cameras - 21. Each group of addressable cameras contains a block of local - 22, which by means of the channel switching 2 connected group of addressable cameras 15 (about what her number m). Malacatoya surveillance system for monitoring the longest borders in the General case contains n groups of local areas (zones) 21 addressable video camera 15, which by means of the channel switching 2 is connected to the Central control unit 3.

Figure 4 is a diagram of location malokakhovka surveillance system for monitoring the longest borders in the organization of odnorangovogo long security line. Territorial group of local areas 21 with addressable video cameras 15 are arranged successively along the protected object. Options for implementation of local areas 21 with addressable video cameras 15 (options figa and figb) differ in the location of the local unit 22. In the first case, the local unit 22 is located at the end (edge) of the local area, in the second case - in the middle.

Figure 5 shows the scheme of location malokakhovka surveillance system for monitoring the longest borders in the organization of deflanguage long security line.

The first variant of the proposed system (figure 1) works as follows. The camera 1 is installed on the local stretch of the long security line and is connected with the first input/output channel switching 2 to the Central control unit 3. The rest of the inputs/output of the channel switching 2 are for connecting other video cameras (total m). Channel switching 2 made in the form of bilateral communication interface and is designed for transmitting video frames in a digital form from the video camera 1 to the Central control unit 3. In the opposite direction from the Central control unit 3 of the camera 1 receives the command information, which provides a choice of operating modes of the video camera 1. The field of view of camera 1 covers the land area along the security line. Camera 1 operates in the visible wavelength range. Alternatively, it is possible to work in the infrared wavelength range as thermal imaging cameras. The image of the region through the optical window 4 and further through the first lens 5 focuses on the first image sensor 6 (for example, a CCD matrix), which converts the image into electrical signals. These signals are sent to the digitizer 7 and then input to the display controller 8, which converts the digitized video signals in the video. The compressor unit 9 compresses frames of the video image (for example, MPEG-4) and passes them to the buffer 10, which ensures the operability of the video camera 1 in two modes: in the first mode - save predriving, anxious and positionig frames of an image signal from an external sensor (alarm), and the second mode is a continuous allocative ' is the observation by the operator of the Central control unit 3. The buffer 10 is made for the cyclic overwriting information with the address selection signal from an external sensor (alarm) 3 zones of memory to store image frames predriving, anxious and positioni information. This scheme buffer 10 is well known and disclosed, for example, in the description of the famous " Device pairing" (see author's certificate No. 303322, IPC G06F 13/00, publ. 1989). The buffer 10 in the first mode performs continuous cyclic overwriting of incoming information (e.g., ring) with a certain frequency until then, until it formed a signal from an external sensor (alarm), which is the input for an external sensor 14 is supplied to the camera 1 and then to the processor 12, which in turn sends a control signal to the buffer 10. This signal buffer 10 suspends the process of cyclic overwriting of information (by stopping the conversion of addresses) and saves a certain number of frames predriving, anxious and positioni information corresponding to the selected address by the memory areas. It should be noted that these zones physically can consistently be placed in different memory areas, as the translation address is not synchronized with the time of occurrence of a signal from an external sensor (alarm) and can be ostanovlen any time. Further, the buffer 10 initiates the process of sequential issuance of stored image frames in the interface unit 11, since predriving frames, continuing to transmit alarm and ending positionname frames. The serial transmission interface unit 11 of the information in the channel switching 2 occurs with a slower frequency than the frequency of the write buffer 10) to ensure high-quality transmission of image frames for channel switching 2 having when using the communication cable of any type minimum possible bandwidth of 3 kHz. In the Central control unit 3, which is made in the form of an automated workplace (AWP) with personal computers, the received video information is sequentially displayed on the monitor for review and adoption by the operator solution of the disturbing situation that has arisen on the local section of the security line. When the detailed view video frames (predriving, anxious and positiony) the operator identifies the offender and decides to turn on the alarm. If the operator is satisfied that the alarm has arisen as a result of exposure to noise and interference factors (changes in weather conditions, movement of animals or birds, etc.), the system alert is not included. All videos received in the Central the control unit 3, stored in archival memory operator workstation. The operator can increase the functional reliability of the system due to the quality of received video images by throttling predriving, anxiety (typically one frame) and positionig image frames, and the frame rate (number of frames per unit time) for reliable detection and identification of the offender. Commands from the operator through the bilateral channel switching 2 are received at the first input/output interface unit 11 and then through the second input/output are on the third input/output processor 12. The processor 12 decodes operator commands and sends control signals through its output to the second input buffer 10. The control signals control the operation modes (the first or the second mode), as well as a number of the above mentioned frames and frequency shifts. The second mode of operation different from the first so that the buffer 10 provides a continuous allocative surveillance by the operator of the Central control unit 3. The buffer 10 in this case is used as a stack memory for sequential accumulation process, promoting the stack and continuous delivery on the output image frames. The processor 12 when this blocks the signals received at the input for external sensor 14, and prednisone, anxious and positione Adri image is not formed. The buffer 10 provides only a different writing speed and reading its input and output. The intensity of the continuous malosadovaja surveillance (number of frames per unit of time) can also be adjusted by the operator. Communication between the processor 12 and the display controller 8 provides their interaction to ensure the operability of the video camera 1. All the processes occurring in the camera 1, are performed under control of a computer program that is stored in the storage device 13.

The second version of the system in contrast to the first variant provides the performance of the system in mode day/night backlit viewing camera at night using IR-illuminator. Structural diagram of a second variant of the system shown in figure 2. For the operation mode day/night inside the camera 15 entered the second lens 16, an optical filter 17, the second image sensor 18, the switch 19 video and IR illuminator 20. In contrast to the first variant of the system figure 2 shows a coupling between the elements 18-19, 6-19, 19-7, 12-19 and 12-19.

The second variant of the proposed system (figure 2) works as follows. The second lens 16 with the optical filter 17 and the second image sensor 18 create inside a video camera 15 second channel that is different from the first channel (the first volume of tiva 5 and the first matrix image 6) presence of optical filter 17 to work at night. Many well-known video cameras day/night only have one channel with an optical filter, which mechanically (damper) is inserted at a certain position in the channel at night and extracted from him during the day. It is known that the mechanical driving elements are less reliable than their electronic counterparts. Use the second (backup) channel is usually restrained by price and constructive reasons (increase in size), but if microminiaturization electronic components and reduction of the efficiency of using two channels of the review became a reality. Thus, in the camera 15 are not used driving mechanical parts, and the first and second channels of the review switch electronic switch video signal 19 to the signal processor 12. That is, in the day time running the first channel (used elements 5-6-19-7), and at night turns on the second channel (used elements 16-17-18-19-7). Besides, additionally at night on the second channel of the review included IR projector 20 according to the signal processor 12. In figure 2 the dashed line shows that for highlighting areas of review may also be used spotlight 20 located on the outside of the camera 15.

The third variant of the system in contrast to the first or second Varian is s provides surveillance and control groups local areas of long security line. In the proposed third embodiment of the system in addition to the first (1) or second (2) options to the channel switching is connected group of addressable cameras (total m)installed on other local areas of long security line. Channel switching 2 made in the form of transmission of information by wire, optical fiber or radio through bilateral serial communication interface.

A third option proposed system works as follows. Alarming situation caused by the signal from the external sensor 14 in one of the areas longest security line, is transmitted to the Central control unit 3 with the address (number) of a particular camera 1 or 15 for operator viewing predriving, anxious and positionig image frames. The operator may also connect to any video camera from a group of discretion by issuing the channel switching 2 the corresponding command on the camera with the specified address (number). When using fibre channel connection of the Central control unit 3 and the interface units 11 cameras 15 must be equipped with fiber-optic transceivers, and the use of radio communication - relevant radio frequency wireless transceivers (radios)./p>

The fourth variant of the system in contrast to the third option provides surveillance and control of long security line, given the remoteness of the areas of control and possible unevenness of their territorial location. Structural diagram of a fourth variant of the system shown in figure 3, which depicts the system is divided into groups of local areas (zones) 21 addressable cameras. Each group of addressable cameras contains a block of local 22, which by means of the channel switching 2 connected group of addressable cameras 15 (total m). The system generally comprises n groups of local areas (zones) 21 addressable cameras through channel switching 2 is connected to the Central control unit 3.

The fourth variant of the proposed system (figure 3) works as follows. Alarming situation caused by the signal from the external sensor 14 in one of the areas longest security line, is transmitted through a unit of local 22 of the Central control unit 3 with the address (number) of a particular video camera 15 and the address (number) group of local areas 21 for operator viewing predriving, anxious and positionig image frames. The operator may also connect to any video camera 15 of any group of local areas 21 on its usmo the rhenium by issuing to the channel switching 2 the corresponding command on the camera with the appropriate addresses. The local unit 22 is a known device and in the simplest case performs the function of the electronic switch channels interface (HUB), i.e. the function of a hub camcorders group of local areas. Given the remoteness of local units 22 from the Central control unit 3, they can be additionally equipped with known systems, lightning protection and power.

Given the characteristics of the territory and landscape of the protected object, the surveillance system can be organized in different ways. Figure 4 is a diagram of location malokakhovka surveillance system for monitoring the longest borders in the organization of odnorangovogo long security line. Territorial group of local areas 21 with addressable video cameras 15 are arranged successively along the protected object (for example, along the borders of the State border of the Russian Federation, along the pipeline, along the railroad tracks and the like). Options for implementation of local areas 21 with addressable video cameras 15 (options figa and Fig) differ in the location of the local unit 22. In the first case, the local unit 22 is located at the end (edge) of the local area, in the second case - in the middle.

Figure 5 shows the scheme of location malokakhovka system view of the observations for extended control of the borders in the organization of deflanguage long security line.

The field of view of the camera 15 in the basic version should consistently and evenly to cover the protected area along the security line. Pets also have the video camera 15 unevenly, grouping and focusing them on the areas most likely to appear offenders. The video camera 15 can extend their areas of review are necessary to protect local geographically located zones, and all of the necessary scope of protection in General.

It should be noted that instead of all cameras or instead of some of them can be used a thermal imaging camera operating in the infrared wavelength range.

The principle of digital video technology on low-wired to the mains connection in accordance with the Protocol of the serial interface (RS - 485, RS - 232, CAN) enables you to transmit in the band of 3 KHz, which allows the use of all types of communication cables. Given the remote location of the extended borders of the self, this fact allows to reduce material costs for creation of the whole system (using cheaper cables).

Current laboratory models of the first, second, third and fourth variants of the system were subjected to all-season tests in one year. Was confirmed by stable performance of existing laboratory maketo the detection and identification of offenders against the background noise, due to changing weather conditions.

Introduced in the known device, the additional features and functional ties allow you to attach the variants of the proposed system significant new properties and to expand the scope of the system for protection of local areas, areas, restricted areas of control, and extended the borders, such as the State border of the Russian Federation, pipelines, Railways, etc.
