The invention relates to the field of security alarm system, in particular to the mobile means of video surveillance, intended for the detection and identification of the infringer, penetrating through the detection area of the extended foreign protection and caused the reaction of sensors of protection.
One common way of surveillance of protected areas, which are traditionally used video cameras, situated in places (points) control and transmit video information through the backbone to the Central control of the operator. Adopted by the video information is continuously displayed on the screen of the monitor and is recorded in the device archive. To view video images from several cameras is used multiple monitors or a monitor with the ability to switch (multiplexing) video images from different cameras.
When a large number of video cameras installed on the lengthy objects of protection, such as the milestones of the State border of the Russian Federation or trunk pipelines, traditional methods of surveillance becomes unsuitable due to the complexity, large volume and high cost of equipment, and also because of the routine work of the operators, which has a huge project on detection and identification of the offender in the vast quantities of video information. Functional reliability of such systems for detection and identification of the infringer unacceptably low.
Functional reliability can be improved using the principle of video surveillance. The essence of surveillance is that the captured still image is stored in buffer and then transferred with the slow speed at the point of reception, while maintaining good quality (performance considerably inferior in favor of high image quality). To increase the transfer speed in systems use compression algorithms, which allow to transmit the image areas with the change of the plot with high resolution, and other parts of the image (without changing the plot) - low.
When the protection extended sections are typically used stationary video system, where video data is transferred over the wire communication channels. Such systems are quite expensive and do not provide, in case of violation of the communication lines or ongoing repair works of the «closure» of the protected area. Stationary system are unacceptable well as the protection of the movable objects in camps (for example, trains, trucks etc). For such purposes, you must use mobile CCTV system with the transmission of video information on radio channels of communication. Mobile systems is also advantageous to use by frequent change of the objects of protection depending on the various emergency situations (terrorist threats, accidents etc).
A common drawback of well-known CCTV systems with radio channels of communication consists in the lack of functional reliability of systems for the detection and accurate identification of the infringer. Such systems include, for example, known system of «Multi-residence monitoring using centralized image content processing)procedure described in US patent no 6538689, IPC H04N 7/18, publ. 2003 and comprising: a group of cameras and a group of speakers, a group of microphones, group of bilateral communication channels, a Central control point, the processor of the video image (image content processor) and monitor. This monitoring system with centralized processing of image content provides connection of multiple remote cameras to the video processor, located in a Central monitoring point, through individual radio communications. To control the video monitor is used. The operator can switch the video image in the manual mode, with the channel. At automated mode processor video makes analysis of the image content (filtering) and has a video on priorities, placing on the monitor image corresponding to the higher priority. The processor can also shoot thin image or display images in slow motion.
Given the possibility of connection to the Central checkpoint in the system of a large number of remote cameras, the system has a finite bandwidth.
Similar essential features of the claimed and the above-mentioned system are: a Central control point and the group of far cameras that transmit video over the individual radio communications.
The disadvantage of this system is that the system can lose important information fast changing subjects due to a lack of buffering image frames in the video cameras. When the system is in the manual mode the operator decides which camera mount, due to which important information can be lost. Another disadvantage of the system is the lack of registration at the signal triggering external sensor (alarm, video frames, relevant , disturbing and situation in the field of view video camera.
The deficiencies noted partially eliminated in the other, the closest to the technical nature of the claimed invention known to the system, Wireless video security system with pre-alarm buffer»is described in US patent no 2005/0128295, IPC H04N 7/18, publ. 2005 and consists of: a control panel, which consists of the radio modem (RF transceiver) with receiving and transmitting antenna, display and storage device; and a variety of sensors protection for intruder detection, each of which contains a radio transmitter alarm signal to the transmitting antenna; and also a lot of video cameras with a battery or rechargeable power sources, working in a non-active standby mode for low power consumption, or in active mode, video surveillance for a specified period of time with the increased energy consumption when the sensor of protection via radio channel alarms. Each camera includes receiver alerts (wireless receiver with antenna reception and buffer. The «Wireless network security system with buffer» works in normal standby mode and switch to the active mode at the alarming signals from sensors protection, which include cameras in active mode video control. buffer each camera is a buffer ring-type and allows you to save a relatively small number of video frames (for example, ten), made over a relatively short period of time (for example, within ten seconds) due to the restricted capacity of the battery or rechargeable power sources. Security sensors in the system are not tied to the camera, the number of those, and others may be different. Each sensor protection system may include a radio channel all your camcorder to record and send a message to the control panel, which, in turn, sends a radio channel CCTV signal transmission of recorded images. The data transmission process video data from video cameras on the control panel is in mode. All the video information is stored in a storage device the control panel and can be controlled by an operator using the graphical display.
Similar essential features are: control panel, which consists of radio with receiving and transmitting antenna, display and storage device; and a variety of sensors protection for intruder detection, each of which contains a radio transmitter alarm signal to the transmitting antenna; many cameras with buffers, working in a non-active standby mode for low power consumption, or in active mode, video surveillance for a specified period of time with the increased energy consumption when the sensor of protection via radio channel alarms; the receivers of signals with foster antennas; battery or rechargeable power supply.
The disadvantage of this system is that the system uses combined radio channel. Alarm messages from sensors protection and transmitted the video data to the Central control panel can be superimposed on each other, which can lead to loss of important information on the identification of the infringer. Another disadvantage is the inability of the system functioning in the night time due to the lack of highlighting areas of surveillance cameras using infrared illuminators. The disadvantages include a lack of vandal resistance cameras. Control panel system can be protected by one of the video cameras aimed at the place of its location. And they themselves camera is not equipped with sensors protection, covering the approaches to them and protecting them from attack by malicious users. As a disadvantage, you must also specify a limited range of the radio channel when using the system for the protection extended by the length of the borders (for example, protection of the State border of the Russian Federation) due to the absence of intermediate repeaters radio signals.
The objective of this invention is to increase the functional reliability and extend the scope of the system.

The first version of the proposed system (figure 1) is as follows. The first paragraphs of video 9 (number n) are installed on the local sites of extended foreign protection. The first camcorders 14 and the first IR-illuminators oriented to the terrain in the direction of 25 on an observation area to one side. Orientation in space can be carried out in azimuth and elevation. In the initial state, first paragraph of the videocontrol 9 with a battery or rechargeable power sources 10 are in the inactive (standby) to ensure low energy consumption. Safety sensors 6 (number n) with transmitting antennas 8 installed, e.g. in the area of access to a boundary protection for early indication on the first radio channel 11 on the worrying situation of near foreign protection. The first items on the videocontrol 9 accept messages from sensors of 6 from the receiver alerts 12 through the receiving antenna 13. When an alarm message is caused by the infringer, included the first video camera 14, first paragraph, of the videocontrol 9 in active mode video control within a specified period of time, which is characterized by increased energy consumption. Each sensor protection 6 with its sequence number (address) «attached to the first paragraph of video 9 with the same sequence number (the address)that eliminates confusion between the areas of observation 25 and assigned sensors protection 6. Moreover, this «binding» eliminates the possibility of inclusion in active mode video control all at once the first items of video 9 one alarming message from one sensor protection 6 that provides energy saving system. In active mode video control video information from surveillance zone buffered 15 first camcorder 14. Buffer 15 is a circular buffer and saves pictures , disturbing and video information for further transmission to the mode to the Central control panel 1 on the second radio channel of communication 18. Alternatively, you may be saving and sending only disturbing and video for more efficient energy consumption. Central remote control 1 takes a picture using the first radio modem 2 through first receiving-transmitting antenna 3. Upon request of the operator frames received video data can be viewed on the graphic display 4 for a detailed analysis of the alarming situation in the surveillance zone 25, identification of the infringer and a decision on his detention. After testing the alarm situation and making a decision, the video data is written to the storage device 5 for long-term storage and maintenance of the archive data. The first paragraph of video 9 after completion of the procedures for the transfer of video data to the Central control panel 1 becomes inactive (standby) mode expectations to ensure low power consumption of battery or battery power source 10. During the night to obtain quality images in the surveillance zone is included on the first IR projector 21. Switch-on signal is formed by a team from the Central control panel 1 arriving at the second unit 16 on the second radio-channel 18 and then switching bus 22 to the first IR projector 21. The first discovery tool 20 is intended for the organization of protection of the first paragraph of video 9 and can be represented, for example, seismic or radiowave dome sensor, closing approaches offenders to video control item 9 out of the zone of observation. The first discovery tool 20 should trigger at the approach of the offender to the rack with tripod 24 and the exercise by the vandalism. Technical solutions for the implementation of the first detection tools are well-known. The principle of action and algorithms of functioning are described in detail in the technical literature, for example:
- in the book «perimeter defense Systems,» the authors .. Shanaeva and A.V. , publishing house «Security Focus», Moscow, 2011, in subsection 2.11. «Seismic detection tools», p.100-107 in section 2.15. « microwave (radio wave) detection tools», .137-144, www.iss.ru.
Processor 19 is available to control the first camcorder 14, the first IR-spotlight (on/off), the receiver signals 12, second radio modem 16, as well as for making signals unauthorized approach to the first paragraph of the videocontrol 9 from the first detection tools 20.

In the claimed invention processor feature 19 for the first variant of the system is to manage and four of information flows (see figure 1):
(a) the communication from the sensor protection 6 adopted by the receiver alerts 12, is transmitted on the first video camera 14 for inclusion in active mode video control (sequence transfer from element to element 12-19-14);
The first radio channel 11 and the second channel of communication 18 operate at different frequencies (for example, 433 MHz, respectively, 868 MHz), that provides uninterrupted transmission of radio broadcasts without loss of information and without mutual influence. The first radio channel 11 sends alarm messages from sensors of 6, and the second channel of communication 18 - videos from the first items of video 9 to the Central control panel 1. Safety sensors 6 can operate on different physical principles of action (for example, , infrared, vibration, seismic etc) and can be located geographically as inside the boundary of protection, and on approaches to it.
The structural scheme of the second variant of the system is shown in figure 2. The second version of the system works as follows. The system contains a Central control panel 1 from the first receiving-transmitting antenna 3, sensor group of 6 (number n) with transmitting antennas 8. As an alternative to the first variant of the system, the second version of the system instead of the first group points of video 9 (number n) contains the group of the second paragraphs of the videocontrol 26 (number n) with a battery or rechargeable power sources 10, working in a non-active standby mode for low power consumption, or in active mode, video surveillance for a specified period of time with the increased power receipt from the sensors of 6 on the first radio channel 11 alarms, and each second paragraph of the videocontrol 26 in addition to the content of the first paragraph of video 9 are added: the second discovery tool 29, the second IR projector 28 and the second video camera 27, which is composed of buffer 15, designed to save , disturbing and video, and the second IR projector 28 and the second camcorder 27 are connected to the switching bus 22, and entrance/exit of the second detection tools 29 is connected to the third input/output processor 19. Second paragraph of the videocontrol 26 (number n) are installed on the local sites of extended foreign protection. The first and second camcorder 14 and 27, as well as first and second IR-illuminators 21 and 28 oriented to the terrain in the direction of 25 on their surveillance zone and are directed to different sides of the extended boundary of protection (see figure 3). The presence of the second paragraphs of the videocontrol 26 double set of video cameras, IR illuminators and means of detection can save on uprights with tripods and protective casings, having them along the long, foreign protection through times compared with the location of the stands with tripods and protective cases in the first version of the system. An example layout is shown in figure 3. Processor feature 19 in the second version of the system extends to the possibilities of control and commutation of eight information flows. To the four existing lines of the first version of the system (12-19-14), (14-19-16), (20-19-16) and (16-19-21) added four other areas (12-19-27), (27-19-16), (29-19-16) and (16-19-28) with similar functions. The second tool detection 29 may function as a designation of a longitudinal axial line of the foreign protection. In this case, it should be implemented on the radiation principle ( or infrared beam) with a narrow detection zone. The second discovery tool generates in the direction of orientation camcorder 27 narrow, invisible to the human eye beam, when you try to override the violator, a signal operation. Time for the second detection tools will meet alarming information, which is formed at this time in the buffer 15. That is the second discovery tool will perform the function of «binding» or synchronize the time frame the alarm information to the moment of crossing the infringer of the longitudinal axis (virtual) line foreign protection. This function can be used to highlight further the number of frames of video information only disturbing video. Footage recorded in the buffer to this frame will be «»and after the shot - «». Technical solutions for the implementation of the second detection tools are well-known. The principle of action and algorithms of functioning are described in detail in the technical literature, for example:
- in the book «perimeter defense Systems,» the authors .. Shanaeva and A.V. , publishing house «Security Focus», Moscow, 2011, in the section 2.16. «The dip microwave (beam) detection tools», .144-156 section 2.14. «Active infrared detection (IR barriers)», pagination 126-137, www.iss.ru;
- in the catalogue of the equipment of firm «Optex» (Japan), Security alarms, equipment Catalogue 2012, www.optex.ru. In the claimed invention may be applied one of the infrared detectors of this company, designed for perimeter protection, for example, AH-350 DH MKIII.
In the rest of the second option, the system works like the first option of the system.
The third version of the system (figure 3) is as follows. The first paragraphs of video 9 and, second paragraph of the videocontrol 26 are located along the long, foreign protection. The system may use a different combination of the first and the second paragraphs of video depending on the tactical problems of protection. Video from the first and the second paragraphs of the video control is transferred to the Central control panel 1 from the use of the second radio communication. When a remote location Central control panel 1 from the turn of protection may be used repeaters 30. Figure 3 shows an example of the third version of the system in which the safety sensors 6 represent a seismic detection of circular detection zones. Safety sensors 6 are located in the zone of the access to the basic boundary protection at some distance. When moving target (the offender) in the direction of the turn of the protection of the sensor activates protection 6 (figure 3 - second), which sends an alarm message to the relevant paragraph of the videocontrol 26 on the first radio channel of communication. Item videocontrol 26 (figure 3 - second) goes into active mode, includes a video camera and saves , anxious and video information in the buffer. Further, the accumulated frames of video are transmitted in mode sequentially in time through a second channel of communication to the Central remote control 1 through a repeater 30 (figure 3 - PT2).
Figure 4 is an example of construction of the second paragraph of the videocontrol 26, which consists of a carrier rack with tripod 24, where are fixed receiver alerts 12 with a receiving antenna 13, the second unit with 16 second receiving-transmitting antenna 17, the first 14 and the second 27 camcorder, the first 21 and 28 second IR-illuminators. At the bottom of the counters under the tripod is located in the protective housing 23, which contains 19 processor and battery pack or battery power source 10. Unlike a prototype system in which the battery or rechargeable power supply constructively located inside of the cameras, in the inventive system battery or battery power source 10 is common to all electricity consumers, is located in a separate building and can be more powerful than the power source camcorders system prototype. The first and second video camera, and the first and second IR illuminators are fixed on the front with a tripod using mechanical components that allow them to Orient the direction on the terrain in azimuth and elevation. The first 20 and 29 second detection tools (not shown in figure 4) are connected to the processor 19 through plug-type connections on the protective housing 24 by communication lines. Construction of the first paragraph of video 9 similar to the design of the second paragraph of the videocontrol 26 except from its composition the second video camera 27, the second IR spotlight 28 and the second detection tools 29.
Mobility claimed system is ensured by the possibility of placement of the first 9 or 26 second video control points on the terrain along the long, foreign protection when using racks with sliding tripods.
The monitoring area of the first and second paragraphs of the videocontrol must consistently and uniformly cover the protected area along the boundary of protection. Pets also have the first and second paragraphs of video unevenly, grouping and focusing them on areas most likely appearance violators. The declared system can also be applied for the protection of local territorial zones, sites, areas and all necessary field of protection as a whole.
Existing laboratory models of the first and second versions of the system were all-season tests in one year. Was confirmed by the stable operability of the existing laboratory for detection and identification of offenders against the background of interference caused by changes in weather conditions.
Introduction to known system of additional signs and functional connections make it possible to add options to the proposed system of significant new properties and extend the scope of application of the system for protection of local areas, areas limited control zones, and extended the borders. Special role is given to the protection of the movable objects in camps (protection of trains, trucks etc), as well as protection of industrial and military objects in various emergency situations (terrorist threats, accidents etc). Objects of protection may also be such large objects, as the State border of the Russian Federation, main pipelines, Railways etc.
