The role of AI and predictive analysis in modern physical security

In the 2000s, users started to see object recognition, facial recognition, and behaviour recognition. In 2010, they started to see facial recognition bolstered by deep learning, the connection of smart devices like cameras, locks, and sensors into integrated security systems.

And in the 2020s, the current innovations focus on automation, end-to-end integration, and making better use of data captured by AI and analytics.

AI-enabled cameras

There’s almost no limit to the amount of information that AI can deliver from a captured scene

From that early analytical tripwire in the 1980s, AI-enabled cameras can do so much more.

There’s almost no limit to the amount of information that AI can deliver from a captured scene: if a vehicle is at a standstill or moving too fast if someone has gone into a prohibited area or if people are grouped, it can even identify objects like guns and axes, detect body language and tell if someone is shouting. 

Object detection

One of AI’s greatest strengths is its ability to detect the presence of the abnormal or the absence of the normal but it is advancing all the time and its use is growing: according to the World Security Report, over the next five years, 42% of Chief Security Officers (CSOs) surveyed intend to invest in AI and AI-powered surveillance within their physical security operations.

This investment is aimed at enabling physical security operations to react swiftly and accurately based on available data. AI, along with biometrics and facial recognition technology, is seen as top priorities for future investment.

Leveraging data

CSOs expect security providers to leverage data to generate insights that prevent security incidents.

Noah Price wants to expand on how it can be used to great effect already in physical security and suggest what it might be able to do in the future.

Scalability

AI scales well, whether it's running on an on-premise server network or in the cloud

AI enhances the ability to detect threats through the continual, vigilant monitoring of security footage or data. It can do this at a much greater speed and scale than humans ever can simply because it doesn’t need to sleep and won’t lose concentration. This allows for much larger volumes of information to be analysed with high accuracy.

AI scales well, whether it's running on an on-premise server network or in the cloud. Adding more cameras or other data sources does not necessarily require drastically more resources to compute like it would hire more humans to monitor.

Autonomous drones

Automated systems like cameras and sensor-equipped drones can expand coverage and access to remote physical areas, complementing ground-based sensors and security.

Regulatory aspects around visual line of sight and autonomous drones are still evolving in certain countries, but AI-powered drone flight promises to be an exciting option for covering large areas.

Predictive analysis

The application of predictive analytics powered by AI is rapidly becoming an integral part of modern physical security solutions. Sophisticated machine learning algorithms can process volumes of data gathered by networks of cameras, access control systems, perimeter sensors, and more.

The goal is to identify patterns, anomalies, and correlations that enable AI systems to forecast problems or threats before they occur.

Anomaly detection

The system learns to automatically recognise authorised flows versus suspicious incidents worth escalating

For instance, AI can continuously analyse video feeds to detect subtle anomalies in visitor or employee traffic flows compared to historical trends at a particular site.

Unusual activity like accessing restricted areas or tailgating could trigger alerts, prompting a focused investigation. Over time, the system learns to automatically recognise authorised flows versus suspicious incidents worth escalating. 

Detection modes and advantages

Other detection modes might analyse facility entry logs for spoofing attempts, assess raw guard tour data to recommend optimised patrol routes, or even scan social media to anticipate planned protests at sensitive locations.

AI has clear predictive advantages over legacy rules-based approaches. Machine learning allows today's platforms to model complex networks of conditions, adapting dynamically rather than relying on simplistic thresholds.

Proactive forewarning

As a result, pioneering solutions provide proactive forewarning of 10 to 60 minutes or more for threats ranging from unauthorised access to site protests, theft of goods, cyber intrusions, and beyond.

Continued improvements around detection accuracy, false alarm filtering, and actionable incident workflow handling will be ongoing AI research focal points.

Application sectors

AI predictive analytics is already bearing fruit across industries, from supply chains to healthcare

However, the enormous potential to anticipate problems before they manifest using AI predictive analytics is already bearing fruit across industries, from supply chains to healthcare. 

Physical security operations are following suit in leveraging these cutting-edge capabilities as well. Proactive forewarning can be given of 10 to 60 minutes for threats ranging from unauthorised access, site protests, theft of goods, and cyber intrusions. 

Accuracy and detection

While AI security applications show great promise, current real-world limitations exist.

Object detection for weapons and other restricted items is an area of rapid innovation, but accuracy beyond 90-95% remains challenging due to variables like camera angles, visual obstructions, and item concealment tactics. Nevertheless, AI has already proven its ability to augment human detection capabilities when responsibly applied.

Contextual reasoning

Looking ahead, contextual reasoning stands as a frontier for AI algorithms to further improve accuracy while reducing false positive alerts.

With continued development, AI could understand permissible object possession based on location, time variables, authorised credentials, and recognised intent. For example, differentiating a kitchen worker legitimately carrying knives versus a trespasser wielding a similar item as a probable threat.

Binary assessment

Human intelligence and optimised ML deliver the most accurate and reliable threat detection outcomes

Additionally, because AI retains consistent focus and operates by binary assessment of triggered observations rather than unpredictable human judgment, it serves to counterbalance the risk of decreased vigilance in humans over time due to complacency, overload, and confirmation bias after excessive repetitive alerts.

The combination of human intelligence and optimised machine learning delivers the most accurate and reliable threat detection outcomes for the foreseeable future.

Hybrid model

With sustained technological progress, AI's performance will incrementally approach more dependable autonomous analytical capability understanding proper contextual permission in parallel with human security personnel.

However, maximising this hybrid model focused on the unique strengths of both man and machine remains the wisest path forward.

Handling of mundane tasks

AI is already demonstrating usefulness in taking over routine security monitoring functions. Video surveillance oversight, access control supervision, and standardised patrol duties are early examples where algorithms can perform continual rather than sporadic vigilance without distraction.

This frees personnel to focus their cognitive strengths on investigative judgment, suspect engagement, and strategic oversight requiring human perceptions.

Multi-modal sensory technology

AI-enabled robots and drones equipped with multi-modal sensory technology offer new paradigms

Looking forward, AI-enabled robots and drones equipped with multi-modal sensory technology offer new paradigms for supplementing boots-on-the-ground while collecting invaluable data.

Whether rolling through warehouse aisles or soaring over remote sections of a pipeline, these machines handle monotonous inspection in environments dangerous or labour-intensive for security officers.

Real-time location-indexed analytics

Meanwhile, real-time location-indexed analytics get ingested for everything from inventory analytics to leakage detection to enhancing theft response.

The fusion of learned patterns with human flexibility allows for optimised resource allocation.

Facility assistant bots

People monitor the mission-critical encounters enabled by machines handling mundane but taxing tasks. This force multiplication equation yields expandable capacity improvements as AI offloads grueling demands.

Savvy deployment of assisted patrols and smart facility assistant bots will shed light on corners otherwise left unseen.

AI as a threat

While AI unlocks countless benefits across physical security, users must remain vigilant against potential misuse

While AI unlocks countless benefits across physical security, users must remain vigilant against potential misuse.

As algorithms grow more capable of synthesising credentials, mimicking voices, and spoofing legitimate behaviours, the attack surface widens. AI could power new forms of infiltration if co-opted by threat actors.

Theft due to AI

Users have already witnessed criminals fine-tuning AI to enhance social engineering, phishing attempts, and identity theft in the digital realm.

Physical protection must learn from these offensive advances, forged badges and faked biometric duplicates could be the next frontier if defences lag behind AI's creative potential. This reality demands a balanced posture embracing AI’s strengths while mitigating vulnerabilities it may introduce. 

Collaboration between people and technology

Companies would be wise to run through potential compromise scenarios leveraging AI before rollout, to uncover blind spots and create staff awareness about emerging high-tech deception tactics.

AI should never serve as a set-it-and-forget-it silver bullet but rather operate as an integrated component of defence-in-depth strategies. Thoughtful implementation combined with ongoing scrutiny of its security assumptions makes AI a powerful ally. Maintaining effective collaboration between people and technology in the face of rapidly evolving threats is essential for the coming age of AI-powered security.
