ntroduction

With the rapid expansion of body-worn cameras (BWCs) in law enforcement, agencies must maintain strict control over how digital evidence is stored, retained, and documented. Proper video retention policies and an unbroken chain of custody ensure that body-camera footage remains reliable, admissible, and protected throughout its lifecycle.

Establishing strong standards builds public trust and safeguards the integrity of investigations and courtroom proceedings.

Why Video Retention Policies Matter

Video retention guidelines dictate how long agencies must store body-camera footage. These policies are essential for:

• Meeting state and federal legal requirements

• Supporting investigations, complaints, and court cases

• Maintaining transparency and accountability

• Reducing storage costs through structured retention timelines

Clear policies prevent accidental deletion of evidence and help agencies manage large volumes of video efficiently.

Determining Proper Retention Timelines

Retention periods vary depending on incident type. Most agencies categorize footage into:

Non-Evidentiary Footage

Routine patrol recordings or non-critical interactions.
Common retention: 30–90 days.

Evidentiary Footage

Recordings tied to investigations, arrests, or complaints.
Retention lasts until the case is closed plus mandated additional time.

Special Category Footage

Use-of-force incidents
Officer-involved shootings
Criminal investigations with ongoing litigation

These videos are often retained for years, depending on local statutes.

Understanding the Chain of Custody

The chain of custody documents every action taken on a piece of digital evidence from the moment it is captured. For body-camera footage, this includes:

• File creation

• Upload and storage timestamps

• Access logs

• Editing or redaction events

• Transfer between authorized users

• Exporting for court or prosecutors

A clean, verifiable chain of custody ensures footage remains authentic, untampered, and legally admissible.

How DEMS Supports Retention and Custody Accuracy

A modern Digital Evidence Management System (DEMS) automates key components of retention and chain-of-custody compliance:

• Automatic categorization of video

• Assigned retention rules per incident type

• Tamper-proof audit logging

• Secure user access controls

• Automated deletion after retention expiration

• Comprehensive custody history for courtroom use

This reduces human error and ensures agencies meet legal and operational standards.

Implementing Strong Access Controls

Limiting who can view, download, or manage footage reduces risk and protects evidentiary integrity. Best practices include:

• Multi-factor authentication (MFA)

• Role-based access restrictions

• Supervisor approval for exports

• Alerts for unusual access patterns

• Regular audits of user permissions

Unauthorized access can compromise evidence and expose agencies to legal challenges.

Establishing Clear Documentation and Policies

Agencies must maintain written policies that outline:

• Retention timelines

• Evidence handling procedures

• Authorized personnel lists

• Redaction and release guidelines

• Steps for transferring evidence to prosecutors

• Penalties for mishandling or unauthorized access

Consistent documentation ensures compliance and supports internal accountability.

Training Officers and Staff on Evidence Procedures

Retention and chain of custody only work if personnel understand their responsibilities. Training should cover:

• Proper tagging and categorization of video

• Uploading and syncing footage

• Documenting incident details

• Secure handling and access protocols

• How to maintain an unbroken chain of custody

Regular refresher training ensures procedures remain consistent and compliant.

Conclusion

Effective video retention and chain-of-custody practices form the foundation of a reliable and legally sound BWC program. By adopting clear retention policies, leveraging a secure DEMS platform, implementing strict access controls, and ensuring proper training, agencies can maintain the integrity of their digital evidence and uphold public trust.

These best practices protect officers, support investigations, and ensure that body-camera footage stands strong in court.
