1
Capture
Body-worn and in-car systems record the event with device, date, time, officer, vehicle, and activation information available to the configured workflow.
Agency-Controlled Digital Evidence
On-Premises Police Evidence Workflow
A camera program succeeds only when the complete evidence lifecycle is designed. The workflow must account for capture, secure transfer, integrity, classification, access, retention, disclosure, backup, and recovery.
2
Secure Transfer
Evidence moves from the camera or vehicle recorder through a dock, local network, Wi-Fi, or another configured transfer method.
3
Ingest and Integrity Check
The evidence system receives the file, preserves the original, and uses available integrity controls to detect unauthorized modification.
4
Assignment and Classification
Authorized users associate evidence with an officer, vehicle, incident, case number, category, or other agency-defined metadata.
5
Retention and Access
Agency policy determines retention, permissions, evidentiary holds, deletion approval, and who may review or export a file.
6
Review and Search
Authorized personnel locate evidence by available metadata, review synchronized recordings, and document activity according to agency procedure.
7
Export and Disclosure
The agency creates controlled copies for prosecutors, courts, public-records responses, partner agencies, or other authorized recipients.
8
Backup and Recovery
The agency protects the evidence repository with tested backups, power protection, monitoring, recovery procedures, and capacity planning.
What Agency Control Actually Requires
- ✓Named system owners for evidence administration, policy, records, IT, and backup responsibilities
- ✓Role-based access and an approval process for exports, deletion, retention changes, and privileged administration
- ✓Documented retention categories, legal holds, public-records procedures, and prosecutor workflows
- ✓Capacity monitoring and a plan for predictable growth before storage becomes critical
- ✓Tested recovery procedures, protected backup copies, UPS protection, and incident-response contacts
- ✓Training for officers, supervisors, evidence personnel, administrators, and outside recipients
Security Is a Shared Responsibility
The FBI CJIS Security Policy applies controls across the creation, viewing, modification, transmission, dissemination, storage, and destruction of criminal justice information. A server or camera cannot make an agency compliant by itself.
NIST also emphasizes that preservation of digital evidence requires attention to authenticity, integrity, accessibility, documentation, storage media, and long-term handling.
Deployment Acceptance Checklist
Record a test event on every camera type and activation method.
Transfer evidence using every expected dock, network, Wi-Fi, or manual path.
Confirm officer, vehicle, time, incident, category, and case metadata behavior.
Test normal review, supervisor access, export, redaction, and recipient playback.
Confirm retention, legal hold, deletion approval, audit, and user deactivation procedures.
Simulate a power interruption, network outage, storage warning, failed drive, and restore from backup.
Document software versions, server configuration, credentials custody, support contacts, and escalation.
Have records, prosecution, IT, training, command, and patrol representatives sign off on the workflow.
Frequently Asked Questions
Does on-premises mean the server can be disconnected from all networks?
Not necessarily. The deployment can be designed around the agency network and transfer requirements. Isolation, remote access, updates, backup, and sharing should be addressed during system design.
Does local storage automatically make a system CJIS compliant?
No. CJIS requirements apply to the full lifecycle of criminal justice information and involve technology, access, policy, personnel, networks, physical security, authentication, auditing, and operating procedures.
Who is responsible for backups in an on-premises model?
The agency must ensure a documented and tested backup and recovery plan exists. Responsibilities may be shared with an IT provider or support vendor, but they should be explicit in the deployment plan.
How much storage does an agency need?
Capacity depends on camera count, resolution, recording hours, retention rules, evidentiary holds, duplicate or redundant copies, growth, and backup strategy. A current workload estimate should be completed before purchase.
Can on-premises evidence be shared with prosecutors or courts?
Yes, but the method depends on agency software, recipient requirements, security policy, file size, redaction needs, and local procedure. The export and disclosure process should be tested before full deployment.
