Digital Evidence Management

What is video evidence management for law firms?

Video evidence management for law firms is the infrastructure for receiving, organizing, authenticating, searching, and producing video evidence across active matters. It includes AI-powered indexing to make footage searchable by object, timestamp, and spoken word; chain-of-custody documentation for court admissibility; role-based access control at the matter level; and controlled sharing with co-counsel, opposing parties, and courts.

Can AI solve cold cases?

Not on its own. AI helps investigators reopen cold cases by re-examining archived evidence at scale, transcribing old recordings, reading old files, and surfacing and connecting details a person would not have time to find. It produces leads that a detective verifies and acts on. The investigation, and the decision, stay with people.

Is a DEMS different from a Video Management System (VMS)?

Yes. A VMS is optimized for live monitoring and short-term storage of camera footage. It is not designed to manage evidence for investigative or legal purposes. A VMS does not maintain a chain of custody, enforce retention policies, provide AI-assisted search across recorded footage, or support the access control and sharing requirements of an investigative workflow. A DEMS can connect to a VMS as an evidence source but serves a fundamentally different function.

Scalable platforms allow smaller agencies to start with core capabilities and expand as budgets allow, and government grants are often available to offset initial adoption costs.

More on this page

What information must be recorded in a digital evidence chain of custody form?

A complete chain of custody form for digital evidence must include a unique evidence identifier, date and time of collection, names and roles of everyone who handled it, storage method, transfer records with signatures, hash values verified at each handoff, and a log of all forensic actions performed. Any missing field is a legal vulnerability.

More on this page

Is CJIS-compliant storage the same as CJIS-compliant AI analysis?

No. Storage is about holding evidence securely with chain of custody and access logging, the job of a digital evidence management system. AI analysis is the separate step of processing that evidence to produce answers, and it has to meet the same CJIS controls when it reads the data. An agency needs both, kept distinct so the analysis step does not reopen a risk that storage already closed.

What is the difference between cloud and on-premises evidence management?

Cloud evidence management offers scalability and remote access, while on-premises systems provide direct control over physical infrastructure and local storage.

More on this page

What are the risks of storing digital police evidence on general cloud tools or local drives?

General-purpose storage was not built for evidentiary requirements. It lacks automated audit trails, role-based access controls, and retention policies tied to case timelines. Evidence stored this way is harder to track, easier to access without accountability, and more likely to fail admissibility standards during legal scrutiny.

More on this page

How are audit logs different at enterprise scale?

Departmental audit logs track what users did. Enterprise audit logs have to produce a defensible record across thousands of automated operations, survive regulatory review, and export cleanly into compliance systems. Tamper-proof storage (WORM), complete chain of custody per file, and export-ready formats are baseline requirements, not advanced features.
