Perimeter Detection is an option often deployed to prevent intrusion of unauthorized personnel into secure areas such as airports, maximum-security detention centers, energy plants, chemical plants, water treatment plants and many more. The overall plan objective is to deter, delay, detect, assess, and track, potential or actual breaches of the perimeter in a proactive manner, enhance the efficiency of security personnel in responding to security breaches, and provide a high level of protection for persons and property within the secured areas. Perimeter Detection is a complex commingling of multiple systems that provides advanced warning and threat assessment within a secure perimeter.
Through a correlation of multiple alarms and detected threat contacts, the Command and Control Center operator can quickly identify “targets of interest” and dispatch the appropriate response to neutralize the threat. The systems architectures include four basic elements: Sensors, Video Detection Equipment, threat assessment and Alarm Correlation/Management Systems, and Data Communications Systems. BL Technology has the expertise to provide and install any level of Perimeter Detection needed.
- Sensors
- Barrier sensors are a two-in-one security option. They provide both a physical barrier to intrusion and a sensor for detection. Taut-wire systems are an example of barrier sensors. Volumetric sensors generate an invisible detection field that locates and tracks intruders moving through the secure zone. These sensors include microwave systems, RADAR, and electrostatic detection devices. Fence and wall-associated sensors are above-ground detection sensors that are attached to an existing fence or wall. In the event that vibration due to cutting or climbing on a metal fabric fence is detected, the detection field is considered compromised and an alarm triggered.
- Video Detection Equipment
- Video motion detection systems transform the viewing-only ability of CCTV cameras into a tracking and alarm system. Using advanced software to analyze the video output signal, a detection field is created that can locate and track possible threats within the camera’s perimeter zone. Moving targets, such as intruders and vehicles, speed and direction can be tracked and logged while anomalous static targets, such as a briefcase or package left by an intruder can be flagged as a threat and the appropriate alarm sent to the operator. Video monitoring also provides Perimeter Detection with traditional long-term storage of video for the use of reactive threat analysis.
- Alarm Management Systems
- The Command and Control Systems software continually monitors perimeter detection instrumentation and notifies console operators if any unauthorized change of system state occurs. Intrusion typically triggers multiple sensors such as fence sensors, barrier grid sensors, radar perimeter zones, and video motion detection fields. These alarms are correlated and displayed in a simple manner so that rapid threat assessment can be made and the appropriate action taken. BL Technology has the unique ability to integrate alarm management systems with SCADA and control systems.
- Data Communications Systems
- The Data Communication infrastructure for Perimeter Detection provides connectivity between field-installed instrumentation such as sensors and video cameras, Command and Control file-servers, and operator consoles. This infrastructure is critical to the Perimeter Detection Systems operation and reliability. The systems are usually designed with complete redundancy for all Command and Control Center hub elements including both file and video servers. The Perimeter Detection System Data Communication networks require application awareness and strict quality of service.
