Calculation Tools for Risk and Investment Analysis

Quantifying the Business Case for Evidence-Ready Systems

Introduction to Calculation Tools

This chapter provides four interactive calculation tools to help organizations quantify the business case for evidence-ready surveillance systems. Each calculator addresses a specific aspect of the investment decision: the cost of non-admissible evidence, the return on investment for evidence-ready systems, storage requirements for integrity verification, and the probability of evidence admissibility based on system features.

These tools enable organizations to make data-driven decisions about surveillance system procurement and upgrades. By inputting organization-specific parameters, users can calculate the financial impact of evidence-readiness and justify the investment in comprehensive evidence chain capabilities.

Calculator 1: Cost of Non-Admissible Evidence

Calculate the potential financial loss when surveillance footage cannot be used as evidence in disputes, investigations, or legal proceedings.

Average Incident Value ($)

Incidents Requiring Evidence per Year

Current Resolution Success Rate (%)

Average Litigation Cost per Incident ($)

Estimated Annual Cost of Non-Admissible Evidence

Calculator 2: ROI for Evidence-Ready System Upgrade

Calculate the return on investment and payback period for upgrading to an evidence-ready surveillance system.

System Upgrade Cost ($)

Annual Maintenance Increase ($)

Current Annual Loss from Failed Evidence ($)

Expected Resolution Improvement (%)

Return on Investment Analysis

Calculator 3: Storage Requirements for Integrity Verification

Calculate the additional storage needed for integrity checksums, metadata, and audit logs in an evidence-ready system.

Number of Cameras

Retention Period (Days)

Average Bitrate per Camera (Mbps)

Integrity Overhead (%)

Total Storage Requirements

0 TB

Calculator 4: Evidence Admissibility Probability Score

Assess the probability that your surveillance footage will be admitted as evidence based on system features.

Time Synchronization

Continuity Verification

Storage Integrity

Access Control & Audit

Export Verification

Evidence Admissibility Probability

How to Use These Calculators

Each calculator is designed to provide immediate, actionable insights based on your organization's specific parameters. Input your current system characteristics and operational data to receive customized calculations. The results can be used to justify budget requests, compare vendor proposals, or assess the urgency of system upgrades.

These calculations are based on industry research, legal precedents, and real-world case studies. While individual results may vary, the calculators provide a reasonable estimate of the financial and operational impact of evidence-ready surveillance systems. Organizations should use these tools as part of a comprehensive risk assessment and procurement planning process.
