Managing entry to physical and digital environments through authentication, credentials, and additional security protocols is only a portion of access control. Particularly in large organizations with extensive security scopes, the capacity to identify potential risks and issue alerts plays an important role in averting or minimizing security breaches.
Physical Intrusion Detection Systems (IDS) are security mechanisms implemented by organizations to detect and respond to physical threats entering restricted areas. These systems include video surveillance, motion detectors, doorstops, and glass break sensors. Typically, they are integrated with physical security intrusion prevention solutions like door entry systems equipped with lockdown capabilities.
PIDS can be deployed as standalone systems or as part of a broader security infrastructure, often called a Perimeter Intrusion Detection System (PIDS). In this setup, PIDS are integrated with other security measures like video surveillance and access control, forming a layered defense strategy against intrusions.
Many security setups employ a layered approach, spanning from the outer perimeter to inner zones, creating &#;Concentric Circles of Protection.&#; Each layer is fortified with specific security measures, working together to form a comprehensive defense strategy.
Organizations create a multi-layered defense strategy that enhances overall security resilience by deploying security measures across these concentric circles.
Additionally, cameras are strategically deployed across all concentric circles to provide continuous surveillance and context. They offer visual monitoring of each layer, aiding in threat detection, incident response, and post-event analysis.
This approach ensures early detection, effective containment, and rapid response to security incidents, bolstering the protection of assets and personnel within the secured environment.
This is the first line of defense and typically encompasses the perimeter of the secured area. Intrusion Detection Systems (IDS) are commonly positioned here. They continuously monitor the perimeter for any signs of unauthorized access or breaches, providing early detection and alerts.
Access control systems are typically situated in this layer. They regulate and manage entry into various spaces within the secured area. Controlling access permissions prevents unauthorized individuals from reaching sensitive or restricted areas.
Environmental sensors play a crucial role in this inner layer. These sensors detect changes in environmental conditions such as temperature, humidity, or air quality, which could indicate potential security threats like fire or hazardous leaks. Their prompt detection helps in initiating timely responses to mitigate risks.
Due to their role in layered security approaches and their effectiveness in safeguarding digital and physical environments, Intrusion Detection Systems valued are primarily deployed in high-security sectors such as:
However, IDS usage has expanded significantly into commercial arenas. Operations teams in various industries &#; from water districts to warehouses &#; find them essential for securing their premises. Additionally, office buildings, industrial sites, and manufacturing plants increasingly rely on IDS for enhanced security measures.
Goals of Advanced Perimeter Protection Systems
Deterrence is the cornerstone of perimeter security, aiming to dissuade potential intruders from contemplating unauthorized access. This proactive stance is achieved by strategically integrating cutting-edge video surveillance technology, complemented by robust perimeter alarms and sophisticated access control mechanisms. By seamlessly combining these elements, organizations attain real-time visibility into any anomalous or suspicious activities within the perimeter. This enhanced situational awareness is a powerful deterrent, compelling potential intruders to reconsider their illicit intentions. Additionally, deploying virtual guards or professional monitoring services ensures prompt remote verification of detected anomalies, further bolstering the deterrent effect.
Detection represents the proactive identification and swift interception of unauthorized intrusions within the perimeter. Leveraging state-of-the-art video surveillance technology, particularly high-resolution security cameras equipped with advanced analytics capabilities facilitates the accurate and timely identification of breaches. These sophisticated surveillance systems enable security personnel to promptly respond to potential threats by providing real-time alerts and visual confirmation of suspicious activities. Additionally, the ability to digitally or optically zoom in on specific areas of interest enhances the precision and effectiveness of intrusion detection efforts, thereby minimizing response times and mitigating potential risks.
The concept of denial revolves around fortifying the perimeter to effectively repel unauthorized access attempts while facilitating seamless entry for authorized personnel. This is typically achieved by deploying access control technologies at key entry points, such as biometric authentication systems or monitored security gates. By implementing these stringent access control measures, organizations can meticulously regulate ingress and egress, ensuring that only individuals with the requisite authorization are granted entry. Surveillance plays a pivotal role in this regard, providing visual verification of individuals seeking access and facilitating the seamless integration of video data with access control systems.
The delay segment of the perimeter is strategically designed to impede and disrupt active intrusion attempts, thereby buying precious time for an effective response. Within this segment, video security cameras serve as invaluable assets, providing continuous monitoring and situational awareness. By promptly detecting and documenting intrusion attempts, these surveillance systems enable security personnel to initiate appropriate response measures while simultaneously alerting law enforcement agencies. This delay in the intruder&#;s progress is a critical deterrent, increasing the likelihood of apprehension and minimizing the potential for loss or damage.
The defense perimeter constitutes the final line of defense against unauthorized intrusions, typically involving the active intervention of physical security personnel or professional monitoring services. Upon receiving intrusion alerts, security teams leverage surveillance data to assess the severity of the threat and formulate an effective response strategy. This may involve deploying on-site security personnel to investigate and neutralize the threat or coordinating with law enforcement agencies for immediate intervention. Surveillance data is important in this phase, providing real-time insights into the unfolding situation and facilitating informed decision-making to safeguard lives and assets effectively.
Given the sharp rise in breaches and planned intrusions in recent years, the IDS market is forecasted to grow by over 7% by .
When assessing current IDS technologies for your environments, here are key considerations:
Can the system remain operational and functional throughout the year, even during network or power outages and adverse weather conditions? Complex systems with advanced hardware like sensors, infrared, and fiber-optic wiring may face malfunctions or failures, posing security risks even with high uptime.
The precision of positional information, facial recognition, and other detection capabilities is vital for effectively securing physical perimeters. False alarms or positives not only compromise security but also waste resources.
Stay updated with the latest features, such as tracking, object classification, advanced footage retrieval, and environmental monitoring for optimal detection. Choose an IDS with future-proof software solutions that offer regular updates to tackle emerging threats.
Maintenance in intricate systems with diverse software and hardware components can be expensive. Opt for a low-maintenance system with proactive alerts to ensure proper functionality, accurate reporting, and minimal downtime, thus anticipating and preventing failures.
IDS now provides advanced sensor technology to swiftly and accurately locate intrusions. Features like Motion Plotting enable real-time pinpointing of motion across the coverage map.

Although perimeter security is an incredibly important component of overall security planning, the majority of intrusion alarms that are reported to the police are actually false alarms. Given unprecedented labor shortages, it&#;s understandable that many police departments are exercising caution with their limited resources and now requiring alarm verification before responding to calls.
Recently, The Monitoring Association introduced TMA AVS-01, a standard for alarm verification scoring to provide consistent criteria to help emergency services prioritize incidents. Although the AVS-01 adoption is voluntary, most major central stations across the U.S. have already deployed it and it&#;s rapidly moving towards universal acceptance.
AVS-01 is a framework for alarm monitoring companies to assess and &#;score&#; alarm events. This scoring system enables dispatchers and police officers to allocate resources and prioritize responses effectively.
When a monitoring center receives a signal indicating that an alarm system has been triggered, a monitoring agent evaluates the available information and assigns the alarm a corresponding level. Initially, all alarms begin at Level 1, and the monitoring agent can adjust the level based on additional information as needed, either escalating or de-escalating the response accordingly.
AVS-01 acknowledges that while various types of evidence contribute to alarm verification, real-time video is the most effective for swiftly and accurately assessing alarms and escalating them if necessary. Other verification methods, such as audio-based or motion detection without additional context, typically lack the depth needed to escalate beyond a Level 2 alarm.
MCA&#;s perimeter security solutions integrate professional monitoring with video verification capabilities. Customers can utilize security cameras as alarm triggers through person detection analytics or combine traditional intrusion sensors with nearby cameras for visual context. This approach enables monitoring agents to grasp the context of all alarm events, regardless of the triggering device.
The different alarm levels under the AVS-01 framework are:
No emergency dispatch is requested, typically because the alarm was canceled or the agent confirms there is no threat.
The agent receives a signal but lacks additional information to determine if there is human presence or if the alarm is legitimate. Dispatch may be requested, but it will be assigned the lowest priority, and there might be no police response. This level is typically assigned to events like a motion sensor activation without further context.
There is evidence or a high probability, often from video, audio, or other data sources, indicating the presence of an intruder on the property, although their intent is unknown. Emergency dispatch is requested, and the event is communicated as a Level 2 alarm in progress.
With video, audio, or eyewitness evidence, the agent confirms a legitimate threat to property. Emergency dispatch is requested, and the event is communicated as a Level 3 alarm in progress.
Video, audio, or eyewitness evidence confirms an imminent threat to a person&#;s life. Emergency dispatch is requested with the highest prioritization, and the event is communicated as a Level 4 alarm in progress. Police will be dispatched urgently in this case.

A PIDS typically acts as an early warning system, alerting a site's alarm system while the intruder is still at the perimeter and not yet in a building or other interior area. A PIDS isn't a replacement for surveillance cameras. The two technologies work together, with PIDS providing early intrusion detection while cameras provide real-time assessment capabilities.[6] PIDS are often integrated with other security products like signage, security lighting, intercom systems, or loudspeakers to help deter potential intruders.
