Responsible Forensic Search: Accelerating Investigations While Protecting Public Trust

Law enforcement agencies are facing a growing challenge: more cameras, more video evidence, and greater pressure to deliver investigative outcomes faster than ever before. In England and Wales alone, the Office for National Statistics estimates there were approximately 9.3 million incidents of headline crime in the year ending September 2025, highlighting the scale of demand facing policing and public safety organisations.

While video has become one of the most valuable sources of evidence available to investigators, finding relevant information within hours, days, or even weeks of footage remains a time-consuming task. Ipsotek’s VISuite forensic search is helping investigators locate critical evidence faster while maintaining the governance, accountability, and oversight required for responsible deployment.

Turning Video into Actionable Intelligence

The value of video evidence lies in understanding what happened, who was involved, and how quickly investigators can establish the facts.

Modern forensic search technologies enable investigators to:

• Search for individuals based on appearance and descriptive attributes
• Track people, vehicles, or objects across multiple cameras
• Reconstruct movements and timelines
• Identify associations and interactions relevant to an investigation
• Analyse large volumes of footage more efficiently

As video analytics platforms continue to evolve, solutions such as VISuite are bringing these capabilities together within unified investigation workflows, enabling investigators to move seamlessly from detection to search, tracking, analysis, and evidence review.

By reducing the burden of manual video review, investigators can spend more time focusing on decision-making and case progression.

Beyond Facial Recognition

Public conversations around AI in policing often focus on facial recognition. However, many investigations begin without a known identity.

Investigators may only have witness statements describing clothing, accessories, vehicles, or movements. This is where modern forensic search capabilities become particularly valuable.

Using appearance-based search and AI video analytics, investigators can rapidly identify individuals across large video estates using descriptions such as:

"A person wearing a dark jacket and carrying a backpack." Or: "A vehicle matching a specific description seen near the incident location."

This enables investigative teams to quickly narrow their search and identify relevant footage, even when facial imagery is unavailable or not required for the investigation.

AI-Powered Investigation Workflows

VISuite’s recent advancements in Visual Language Models (VLMs) and natural language search is making forensic investigations faster and more intuitive.

Rather than navigating multiple search filters and technical settings, investigators can describe what they are looking for using plain language.

For example:

"Show me any abnormal behaviour captured between 2pm and 4pm near the station entrance."

AI can also assist with scene understanding, helping investigators analyse events, generate contextual descriptions, and accelerate evidence discovery across large video environments.

The result is a more efficient investigative workflow that helps surface relevant information quickly while remaining under human control.

Privacy, Accountability, and Trust

As investigative technologies become more powerful, public trust becomes increasingly important.

Questions around privacy, proportionality, oversight, and governance are essential considerations in the deployment of advanced investigative technologies.

For forensic search technologies to deliver value, they must operate within clear frameworks that support:

• Human review and decision-making
• Appropriate authorisation processes
• Auditability and accountability
• Data ownership and control
• Compliance with applicable regulations and policies

Human-in-the-loop verification remains critical for ensuring context, accuracy, and accountability throughout the investigative process.

Innovation and Responsibility

The future of investigations depends on deploying technology in ways that improve operational effectiveness while maintaining transparency and accountability.

AI-powered forensic search can help reduce investigation times, improve operational efficiency, and support law enforcement organisations in managing growing volumes of evidence more effectively.

Successful adoption depends on combining advanced investigative capabilities with strong governance, clear operational processes, and responsible use frameworks.

The most effective forensic search solutions are those that help investigators uncover critical evidence faster while supporting the trust, accountability, and oversight that modern policing depends upon.
