DEM Digital Evidence Management Platform

DEM Digital Evidence Management Platform

Digital Evidence Management (DEM) is a management system designed to collect, store, query, and analyze the digital evidence such as videos, audios, and photos from integrated docking stations (IDSs), body worn cameras (BWCs), or other terminals. Adopting a microservice architecture, the DEM supports local deployment and cloud-based deployment. Providing rich services such as evidence management, map-based evidence, evidence tags, and data analysis, the DEM is widely used in areas including public safety, judiciary, emergency, firefighting, transportation, and energy.


Highlights of DEM


Redundant Backup

The DEM supports an active-standby configuration for redundancy. If the active server fails, the standby server automatically takes over to keep the system running properly.



With the AES256 encryption technology, the DEM protects the evidence from being tampered. Also the DEM ensures security and integrity of evidence through the role-based access control.


Cascading Mechanism

Based on the cascading mechanism, evidence files on the lower-lever DEMs can be automatically or manually uploaded to the upper-level DEM for unified management.
