It recognises people, vehicles and behaviours, reduces false alarms and improves response times. It supports perimeter protection, operations, investigations, safety monitoring and remote site management. It is used by logistics, retail, manufacturing, energy, education and public sector organisations.

What is Video Analytics?

Video analytics refers to the automated interpretation of video using AI and machine learning. It enables CCTV systems to understand what is happening in front of each camera without constant manual supervision.

Furthermore, Ai based video analytics in CCTV systems extract information from video frames and compare it against trained AI models. This approach identifies activity, behaviour and potential risks with greater consistency than human monitoring alone.

Key Features

There are a number of key features and capabilities of this advanced threat verification system, including:

• Identifying objects such as people, vehicles and animals

• Analysing movement and tracking paths across a site

• Recognising patterns and deviations from normal behaviour

• Detecting intrusions, unusual activity and safety risks

• Supporting rapid incident verification through evidence snapshots

• Improving situational awareness for operators and control rooms

Many organisations rely on video analytics solutions because it provides consistent monitoring, supports faster responses and delivers a more efficient way to manage risk.

How Does Video Analytics in CCTV Work?

Video analytics in CCTV relies on a sequence of processes that run continuously. Each process contributes to the system’s ability to interpret video and generate accurate alerts.

Frame Processing

Frame processing is the foundation of analytics. The system analyses each frame of video to extract information that the AI model can interpret.

Frame processing typically includes:

• Identifying movement through pixel changes

• Separating foreground activity from background noise

• Detecting shapes, edges and object outlines

• Tracking movement direction and speed

• Filtering environmental factors such as rain or shadows

• Preparing frames for deeper analysis by the AI model

As more frames are processed, the system builds a detailed understanding of activity across the camera’s field of view.

Object Detection and Classification

Object detection identifies what appears in the camera view. Classification determines whether that object is a person, vehicle or something else. This makes alerts more relevant and reduces false positives.

Object classification models are commonly trained on:

• People detection datasets

• Vehicle categories such as cars, vans, lorries or motorbikes

• Animals including foxes, dogs and birds

• Object types such as bags, boxes or tools

• Behavioural patterns such as running, crouching or climbing

Accurate classification ensures that operators receive alerts about genuine risks rather than everyday background movement.

Behaviour Recognition

The next stage examines how recognised objects behave within the scene. Behaviour recognition analytics, fuelled by machine learning algorithms helps the system identify unusual actions that may indicate a threat or safety risk.

Behavioural based video surveillance analytics solutions cover a number of detection scenarios and triggers.

In summary, these include:

• Loitering in sensitive locations

• Moving against expected flow patterns

• Climbing fences or approaching restricted areas

• Tailgating through access points

• Gathering in unusual group formations

• Unexpected movement after hours

• Speed or direction changes that indicate suspicious intent

This behavioural understanding makes analytics more reliable in complex environments.

Event Rules and Automated Alerts

Event rules define what the system should monitor. When an event matches a rule, an automated alert is generated.

Common event rules include:

• Perimeter crossing

• Intrusion into restricted zones

• Object left behind or removed

• Unauthorised vehicle movement

• Loitering for set durations

• Direction of travel violations

• After hours presence detection

Automated alerts provide operators with real time evidence so they can act quickly and confidently.

What are The Different Types of Video Analytics?

Video analytics covers a wide range of features. Organisations choose capabilities based on the environment, site layout and level of risk.

Intrusion Detection

Intrusion detection identifies when a person or vehicle enters a protected area. It is one of the most widely used analytics features, offering benefits such as:

• Early detection of perimeter breaches

• Fewer false alarms than basic motion detection

• Reliable performance in challenging outdoor zones

• Faster operator verification

• Stronger event evidence for investigations

For high risk sites like warehouses, solar farms and industrial sites, finding the best intrusion detection system is critical to protecting perimeters, assets and operations.

Perimeter Monitoring

Perimeter monitoring helps protect large outdoor areas. It reduces false positives by focusing on object recognition rather than movement alone.

Perimeter analytics typically includes:

• Approach detection from outside boundaries

• Entry identification within restricted zones

• Tracking people and vehicles along fence lines

• Handling long range outdoor detection

• Working effectively in low light or adverse weather

Object Tracking

Object detection and tracking analytics follows movement across a site. It is valuable for investigations and real time oversight.

Object tracking supports:

• People tracking across multiple zones

• Vehicle movement mapping

• Timeline reconstruction for incidents

• Identifying patterns that may indicate risk

Loitering and Behaviour Analysis

Loitering analytics identifies when someone stays in an area longer than expected.

In summary, loitering and behavioural analysis for CCTV helps to filter out any usual activity in certain areas, while also analysing and detecting suspicious individuals.

It is used for:

• Retail risk reduction

• School and campus security

• Car park monitoring

• Anti social behaviour detection

• Identifying suspicious activity before escalation

ANPR and Vehicle Analytics

ANPR identifies number plates and tracks vehicle movement. Vehicle analytics supports:

• Access control for controlled areas

• Car park management

• Transport monitoring

• Perimeter vehicle detection

• Incident tracking

Thermal and Low Light Detection

Thermal CCTV analytics detects heat signatures rather than visible light.

Thermal imaging cameras are a key component of CCTV video analytics systems.

Here’s how they work::

• Complete darkness environments

• Remote outdoor locations

• Long range detection

• Early warning for intrusions

• Reduced reliance on lighting infrastructure

As you can see, thermal cameras are highly effective in detecting actual threats to site security. As a result, these, Ai based solutions improve the accuracy of video verification and threat analysis, therefore solidifying site security.
