Perimeter security alarm (TSOP)

Perimeter security alarm systems (PSTN) - design of facility boundary protection with integration and monitoring

The production plant has a perimeter alarm, but it is constantly triggered by passing cars and the movement of birds. Security stops responding to real intrusion attempts because they get tired of false alarms. When expanding the territory of the plant, it turns out that the existing system does not scale and requires a complete replacement of the sensor perimeter. Or the alarm system is not integrated with video surveillance, and when the sensor is triggered, the guard does not see what happened on the perimeter.

This occurs during the superficial design of perimeter signaling. We design the PSTN so that the system reliably detects real threats, does not generate false alarms, and integrates with other security systems.

What is a perimeter security alarm system and why is it needed?

A perimeter security alarm system is a complex of detection sensors (infrared barriers, ultrasonic sensors, fiber-optic cable detectors) installed along the perimeter of the protected area, and processing and warning systems for border violations. TSOP integrates with video surveillance, access control system and security alarm within the perimeter.

For industrial enterprises, warehouses, logistics centers, critical infrastructure and public-sector facilities, PSTN is a critical element of the security complex, often a mandatory requirement of the insurer and regulatory authorities.

Why doesn't a perimeter alarm protect without professional design?

Professional PSTN design is critical to actual system performance. A superficial approach gives rise to characteristic problems:

• Blind spots on the perimeter - incorrect placement of sensors leaves areas through which undetected penetration is possible; the error is detected only during a real incident
• Systematic false alarms - an unsuccessful choice of the type of sensors for the conditions of the facility leads to responses to vehicles, animals, wind and precipitation; security stops responding to alerts and misses real threats
• Lack of differentiation of threat levels - without analytics and filtering logic, the system does not distinguish between a warning signal and a critical intrusion; the operator does not know how serious the situation is
• Isolation from video surveillance and ACS - when the perimeter sensor is triggered, the operator does not see what is happening in this area; countermeasures are delayed, the evidence base is not formed
• Inability to scale - when expanding the territory, the system is not expanded without reworking the existing logic; replacement becomes the only option

Proper design eliminates all these problems before installation.

Our approach to designing perimeter security alarms

• We develop TSOP taking into account the terrain, fences and control zones - analyze the topography of the territory, determine critical penetration points, select types of sensors (infrared barriers for straight sections, ultrasonic for complex terrain, fiber optic for high sensitivity) taking into account climatic conditions and sources of environmental interference
• We integrate alarm systems with video surveillance and access control systems - when the perimeter sensor is triggered, the system automatically switches the video stream to operator monitors in the area of ​​interest, starts video recording in maximum quality, sends an alarm to a mobile phone, and, if necessary, blocks entrances to the territory
• We provide reliable detection and minimize false positives - we set up sensor sensitivity thresholds and filtering logic taking into account the climatic characteristics of the object, design a multi-level alarm system (warning, danger, critical penetration), include in the documentation the requirements for testing the system under various weather conditions

What is included in the design documentation for a perimeter security alarm system?

What standards are used to design perimeter security alarms?

The design of TSOP is regulated by regulatory documents in the field of perimeter security systems, integrated security and protection of critical infrastructure facilities. AYU-Project carries out design strictly according to the current editions of the following documents:

• GOST R 54830-2011 “Perimeter security systems. Classification. General technical requirements. Test Methods" is the main standard for perimeter security systems, establishing classification based on the detection principle, requirements for the probability of detecting an intruder, noise immunity, resistance to climatic influences and test methods in real conditions
• WD 78.145-93 Ministry of Internal Affairs of Russia “Systems and complexes of security, fire and security-fire alarm systems. Rules for the production and acceptance of work” - a regulatory framework for the design, installation and acceptance of perimeter security systems; regulates the composition of technical documentation and the procedure for putting the system into operation
• WD 78.36.003-2002 Ministry of Internal Affairs Russia “Engineering and technical strength. Technical means of security. Requirements and design standards for protecting objects from criminal attacks" - requirements for the selection of types of perimeter detectors, their placement around the perimeter and zoning depending on the security category of the object
• GOST R 53704-2009 “Security systems are comprehensive and integrated. General technical requirements" - the regulatory basis for the design of TSOP as a component of an integrated security system together with ACS, video surveillance and security alarms inside the perimeter
• GOST R 56602-2015 “Low-current systems. Security systems and access control systems. Application Guide" - requirements for the design of perimeter security systems in terms of cable routes, selection of cables and active equipment

For critical information infrastructure facilities and government institutions, the design of TSOP additionally takes into account the requirements FSB of Russia and other authorized bodies for the technical equipment of the perimeters of objects of national importance.

For which facilities is a perimeter security alarm system designed?

We develop perimeter security alarm systems for facilities of various purposes:

• industrial enterprises and production complexes with a large protected area
• warehouse complexes and logistics centers with a high concentration of material assets
• banking institutions and financial organizations subject to Bank of Russia requirements for perimeter protection
• government facilities and authorities with increased security requirements
• fuel and energy complex facilities: power plants, substations, oil terminals
• airports, port facilities and transport infrastructure facilities
• critical infrastructure facilities: water intake points, data processing centers, communication centers
• residential complexes and cottage villages with controlled entrances and perimeter

Why does the construction business trust AYU-Project to design perimeter security alarms?

Perimeter security alarm is the most vulnerable security system to design errors. The installed perimeter cannot be checked in normal mode - real blind spots, incorrectly configured response thresholds and lack of integration with video surveillance are detected only when a real penetration is attempted. AYU-Project eliminates these situations at the design stage:

• Calculation of coverage areas taking into account terrain and climate - for each section of the perimeter, the type of sensor is selected and the detection zone is calculated taking into account the relief, vegetation, precipitation and sources of thermal interference; blind spots are eliminated analytically before installation
• Logic for filtering false positives - sensitivity thresholds and filtering algorithms are included in the project, taking into account the real conditions of the object: transport load, animals, climatic features of the region
• Cross-system integration - TSOP is designed in a single logic with ACS, CCTV and a security alarm system inside the perimeter; joint response scenarios are agreed upon between systems before documentation is released
• Compliance with regulatory framework and requirements - documentation is generated in accordance with GOST R 54830-2011, WD 78.145-93, WD 78.36.003-2002 and RF PP No. 87; for fuel and energy facilities - taking into account Federal Law No. 256-FZ; Expert comments are eliminated free of charge as part of the contract
• 8+ years of experience and proven qualifications - membership in SRO, specialists in the NOPRIZ register, implemented objects across Russia: from industrial enterprises and fuel and energy complex facilities to logistics complexes and government institutions
