CCTV analytics in business: how AI is helping detect loitering, tailgating, unusual behaviour

CCTV technology has come a long way from legacy systems that simply recorded footage. Thanks to modern sensors, computer vision, and advanced software, CCTV has evolved into a smart, proactive, and analytical business tool.

Artificial intelligence has become essential for improving efficiency and extracting real value from existing infrastructure. Using AI-powered CCTV analytics, businesses can analyse behaviour, detect suspicious activity, monitor footfall, and gather valuable operational insights.

In a world driven by data, AI CCTV enables business owners to make informed decisions while dramatically improving on-site security. Here’s how modern CCTV analytics work and why they are transforming commercial security.

Powered by AI

Artificial Intelligence is often used loosely, but true AI involves systems that actively learn and make decisions using cognitive computing to process large volumes of data.

Modern CCTV systems include updated software that sits over traditional hardware, enabling real-time video analysis. Machine Learning algorithms allow CCTV to identify patterns, recognise behaviours, and provide actionable insights.

From gait analysis to facial recognition, footfall monitoring, behaviour detection, and real-time threat alerts, AI-powered CCTV technology is capable of far more than traditional security systems.

A well-known example is Amazon Go stores, which use computer vision and AI to track customer movements, monitor product interactions, and automate payments—all with minimal human intervention.

Now, imagine similar analytical power applied to everyday business CCTV systems. With AI, cameras can observe, analyse, and detect threats before they escalate.

CCTV Analytics in Business

Here are the key ways AI CCTV analytics enhance commercial security:

Loitering Detection

AI CCTV systems can create a Zone of Interest (ZoI) around entrances, ATMs, loading bays, or restricted areas. The system tracks how long individuals remain in the zone and analyses behaviour to distinguish between harmless loitering and suspicious activity.

If someone repeatedly loiters or behaves unusually, the system sends alerts to the monitoring station for investigation.

Tailgating Detection

Tailgating—when someone follows another person too closely—can be a major issue in busy commercial spaces. AI CCTV can identify recurring patterns, monitor individuals returning frequently, and detect when someone follows others suspiciously.

Unusual Behaviour Recognition

Behaviour such as sneaking around corners, inspecting restricted areas, taking photos, or stalking staff can be difficult for humans to notice in busy environments.

AI-powered CCTV learns what “normal” looks like over time and flags unusual behaviour. Operators can also manually review and label events, allowing the system to improve continuously.

Integration with Smart Security Systems

AI CCTV rarely works alone. When integrated with IoT-enabled security systems, businesses unlock even more value:

  • Processing is done online, lowering hardware costs.
  • Authorised users can securely access the system from anywhere.
  • The CCTV system can trigger access control lockdowns during threats.
  • It can activate alarms, lighting systems, and automated deterrents.

This reduces false alarms and dramatically increases site security.

Business Analytics

Modern CCTV doubles as a business intelligence tool. It can track footfall, customer movement patterns, peak times, and dwell duration, offering insights similar to those used by Amazon Go stores.

This data is invaluable for retail layout planning, marketing strategy, staffing decisions, and overall operational optimisation.

Enhancing Security Using CCTV Analytics

Proactive Threat Prevention

AI CCTV helps businesses detect threats before they cause loss. Retailers can track suspected shoplifters, and the system becomes more accurate the longer it runs.

Improved detection can even help lower insurance premiums.

24/7 Surveillance

AI reduces reliance on human monitoring. The system doesn’t take breaks, and when professionally installed, it provides highly accurate detection.

Real-Time Alerts

Alerts are sent instantly to business owners or monitoring centres. With professional monitoring in place, flagged events can be quickly verified in real-time, reducing false alarms while strengthening security.

Challenges With Modern Business Security

Despite the benefits, businesses must also manage ethical and legal considerations. AI CCTV systems collect significant amounts of data, and storing this data brings responsibility.

Businesses must comply with UK laws and regulations including:

  • General Data Protection Regulation (GDPR)
  • Data Protection Act 2018
  • Surveillance Camera Code of Practice
  • Equality Act 2010

Data protection, encryption, and ethical monitoring protocols are essential. Failure to comply may result in fines, legal action, and reputational damage.
