Introduction

ALPR Data: Retention policies vary by jurisdiction (30 days to multiple years). Non-hit records (no investigative value) are typically subject to shorter retention.
Drone Media: Retain based on case relevance. Routine patrol footage may have shorter schedules, while evidence-related captures require long-term preservation.
Surveillance Media: Apply retention aligned with state/local mandates and privacy requirements.

Automated License Plate Readers (ALPR), drones, and other surveillance systems have become essential tools in public safety and law enforcement. They generate massive amounts of Criminal Justice Information (CJI) and personally identifiable information (PII), requiring careful management in archives. Agencies must ensure retention schedules align with CJIS Security Policy while protecting privacy rights and maintaining evidentiary integrity. This blog explores best practices for managing ALPR, drone, and surveillance media.
