3D modeling of security infrastructure

Please, note that this article is automatically translated from Russian into English, so the translation may not be accurate.

This approach allows to calculate the projected level of security or existing security system at various conditions of the environment, optimize the technical solution, to assess compliance with the real system and project documentation.

Currently, the market delivery of safety with the use of physical (engineering) The protection of objects being actively developed. Physical protection system can be implemented at the strategic, commercial, housing and transport facilities.

The strategic objects are elements of the state border, the components of the fuel and energy systems, swimming pools with drinking water and others. Commercial property may be presented to business, shopping, storage and production facilities, and housing - apartments and houses.

Comprehensive safety system may consist of a wide range of hardware and software. It could be video cameras, various sensors (motion, glass break, smoke, heat), alarm systems, alarm systems and engineering facilities. By engineering structures, in turn, include: barbed wire, fences, doors, gates, walls, etc. (watch video)

Services for the design of safety systems now offer hundreds of companies. Quality results, as it is logical to assume that directly depends on the efficiency of our customer project. Research and analysis methods of designing integrated security systems show that firms installers are oriented in the implementation of projects on the expertise of specialists and experts in this field.

In the real world there are many factors affecting the operation of the system engineering and technical protection of the physical objects (PPS). For example, the source of interference for passive infrared sensors is a central heating. If the examiner does not take into account this factor when designing, PPS will generate false alarms due to improperly installed sensor.

Result of errors by experts (eg, failure to account "dead zones" technical means "shadows" created by objects that are on the pathway sensor detection zone) at the organization security facility will be the appearance of errors and vulnerabilities in the protection of the facility..

"Dead Zone"

Many detection tools (DT) alarm system have so-called "dead" zone. These include DT, for example, the most commonly used to protect the premises passive infrared sensors. Caught in the "dead" zone, which is usually located in close proximity to the sensor, the offender may go unnoticed or be

detected with low probability (less than 75%).

Gates of storage space.

If the examiner does not take into account the presence and geometry of the dead zone sensor, the movement of the attacker near the most likely areas of penetration (doors, windows, attics) can not be detected.

"Shadows"

Many of the sensors used is characterized by the phenomenon of "shadow" - moving the offender, who is behind the subject in the detection zone can not be detected. This applies to all passive infrared sensor. Thus, the object in the detection zone provides for a "shadow" which prevents the detection of movement. Similarly, the "shadow" not considered an expert, may lead to the fact that the sensor detected movement of the attacker will not be.

The more complex the system, the more numerous similar factors and, consequently, have difficulty in assessing and accounting. For this reason, a system designed only on the basis of expert opinion, will not be able to perform tasks in full - bugs in the system will be detected only during operation or at the stage of commissioning. In addition, some errors can not be identified and, subsequently, become a source of threat.

To date, the only formalized method is a "method of designing integrated security system object" (patent number 2,219,576 on March 5, 2002), a developer and owner of which is  "Amulet". Based on the way to a team of developers "Amulet" and "Synesis" was established software package and database for the most sought after areas of security - physical (engineering) protection. Program complex and database have completed the licensing of the Russian Federation.

The software can simulate the complex three-dimensional security system on the object model and evaluate the effectiveness of the decision. It allows you to find the optimal solution of the security of the object before the assembly, thus eliminating possible errors of the future system design phase.

Integrated solution

A comprehensive solution, developed by Amulet "and "Synesis" offers everything needed to implement videoanaliticheskih systems at different sites, regardless of their level of complexity and allows us to solve tasks. The solution enables:

• simulate the object of protection by selecting the desired level of detail, taking into account peculiarities of the territory and the object itself;
• model security system, taking into account all the requirements and selection of technical means of detection of an existing database , which are then placed on the object model;
• test, the security model, to estimate the performance, visual and mathematical characteristics of the system model of security.

Ability to identify potential weaknesses in systems to detect even at the stage of modeling leads to a decrease in labor and financial costs of the project implementation and ensures the proper level of security.

Combining the model with the data of the real world

In modeling the objects of protection and security systems used by 3D-model (three-dimensional model), which allows the most complete evaluation of all aspects and take into account nominated by the customer and the level of security requirements. In the modeling method is used "augmented reality", which combines the virtual model and data from the real world. Thus, the data as close to reality and provide a visual and informative model of the project.

Formal justification of the selected configuration of the protection system

The choice of system configuration, security is based on the demands made by the customer (the level of security), technical capabilities, project budget and used the methodological basis. In contrast to the empirical method, which are guided by experts, formal justification can find the best solution. It avoids the increased cost of TDE, which arises because of redundancy in the deployment of elements of (reinsurance expert). Formal justification and avoids gaps in the allocation scheme of detection equipment.

It is believed that to check system settings, as well as quality of work performed by the deployment of TDE, it is difficult. Used in the solutions we developed the software provides all the necessary tools to solve this problem, in particular, to calculate estimates of the complex object's security and compliance requirements put forward by the customer.

Identify vulnerabilities of existing security systems

Developed a comprehensive solution reveals the vulnerability of existing security systems, identifying the most likely strategy of attack and possible behavior of offenders. When constructing the model of the existing layout TDE takes into account characteristics of the protected object and the requirements for the level of security. Thus, we can determine whether the current system requirements and what opportunities exist to modernize it (if necessary).

Calculating line of surveillance under different external conditions

When developing a project placement is determined by the TCO line detection zone which provides the detection of suspicious activity, depending on various external conditions (light level, weather conditions, etc.).

Maintenance facility for three-dimensional model

Videoanaliticheskoy used in the system hardware and software algorithms are used to detect the criteria and conditions of a potential or existing threat (its source may be subject, action, person, animal), to hold her attention, and then track with multi-systems in an existing photo-realistic 3D- model.

Distinctive features of the solution

Simulation (Statistical) 3D-modeling of disturbances and threats

Used 3D-simulation modeling is one of the reliable methods to estimate the system (in this case - a set of TDE) and its response to various stimuli, and to identify its possible weak areas. Used hardware and software tools provides an opportunity to play the random factors of real life, causing the probabilistic nature of possible situations. Simulated 3D-modeling also allows to avoid unnecessary costs of expensive experiments in real conditions. In addition, experiments are often impossible due to the nature of the object under surveillance. Used tools offer greater reliability than using two-dimensional simulation.

With the help of 3D-simulation modeling can reproduce the behavior of the system in space-time. This allows us to calculate the trajectory requiring attention (potentially dangerous) object / person on equipped TDE territory. Number of iterations that can be anything that allows you to check many possible options for action the offender (or other threats) and to identify possible weaknesses in the system.

Photorealistic 3D-modeling of objects of protection and means

The system provides the ability to create photorealistic 3D-models of objects of protection and the technical means of detection. Three-dimensional photo-realistic rendering using computer graphics facilitates the planning, control and decision-making during the interaction with the TDE, as well as in developing the plan and their position and quality control.

Database facilities

When modeling is used updated database available in the market of efficient technical means of detection and surveillance, which will then be used to deploy the system. The choice of vehicle is based on customer requirements and the specifics of a particular security system.
