Top 10 Finalist — Team Triple L
Issued by: Home Team Science and Technology Agency (HTX) and Microsoft
Top 10 Finalist out of 100+ teams. We developed VISTA (Vision Integrated System for Tool Accountability), a technology-driven solution for Prison Services to streamline tool management using computer vision and reinforcement learning, estimated to reduce manual processing time by 75%.

The Problem
In prison environments, every tool brought in by contractors must be meticulously tracked for security. The existing manual process of logging, verifying, and assessing tools is time-consuming and prone to human error.
Introducing VISTA
VISTA consists of two integrated components: a Tool Detection Unit and an Online Form, working together to automate the entire tool accountability workflow.

VISTA Tool Detection Unit
A physical detection station equipped with:
- High-Definition Camera — for computer vision implementation using YOLOv8 for real-time tool recognition
- Weight-Sensitive Platform — for accurate detection of tools placed on the unit
- Display Panel — for clear and concise instructions to users

VISTA Online Form
Once a tool is detected, the form is auto-filled by VISTA — contractors and officers only need to carry out verification. This increases efficiency and reduces human error in the logging process.

Risk Assessment Score
A risk assessment matrix combining “Severity” and “Likelihood” assessments to categorise different contractor visits. Form data is utilised to generate a precise risk score for each contractor visit, enabling:
- More targeted security measures
- Informed decision-making based on tool count, location, and recognition confidence

Technology Stack
Microsoft Azure, Copilot, YOLOv8 computer vision model, and reinforcement learning algorithms.
