FAQ

Digital evidence management, asked and answered

How does DEMS prove chain of custody?

Every touch is logged with user, time, and action in WORM audit logs that can never be altered, backed by hashing and digitally signed integrity certificates that hold up when the evidence is challenged.

What sources can it ingest?

Over 300 formats from any vendor: body-worn camera, CCTV, interview rooms, in-car video, documents, plus citizen uploads and partner-agency submissions through controlled intake portals.

Is DEMS CJIS compliant?

Yes. DEMS is CJIS compliant: encryption, access control, and audit logging meet the CJIS Security Policy controls that apply to a service provider, with the system running in government cloud or on-premises so evidence stays under agency control.

Who uses a DEMS besides police?

Prosecutors preparing disclosure, courts managing exhibits, campus police, corrections, and civilian agencies that handle investigations, anywhere evidence must be collected, analyzed, redacted, and shared without breaking the chain.

How does digital evidence management software shorten case resolution?

It removes the time spent locating and assembling evidence. DEMS consolidates multi-vendor body-worn camera, dash cam, CCTV, and digital files in one repository, transcribes and tags them so they are searchable, and prepares disclosure packages without re-exporting between systems.

How does it help with e-discovery?

DEMS ingests case media and depositions, makes them searchable by spoken word and by object, applies privilege redaction, and shares production sets under controlled, expiring access with every action logged.

What role does metadata play?

Metadata is what makes evidence findable and defensible. DEMS preserves file system and embedded metadata on ingest, adds AI-generated tags and transcripts, and keeps both bound to the chain of custody record so an item's origin and handling can be shown in court.

How does it handle evidence from different sources?

DEMS ingests 300+ formats from multiple vendors, including proprietary CCTV formats, and can pull from VMS platforms and cloud storage. Federated search then runs across libraries and legacy systems, so evidence does not have to be migrated to be found.

Is cloud evidence management CJIS compliant?

Yes. DEMS runs CJIS compliant deployments, with AES-256 encryption at rest, TLS in transit, role-based access control, MFA and single sign-on, and full audit logging, hosted on CJIS-aligned infrastructure including Azure Government. The agency holds the CJIS compliance obligation and these controls support it.
