Where DEM is the platform, this is the whole system built around it: how evidence gets from the scene into a case file, and how an organisation with many branches manages that centrally.

• Non-standard capture. Different officers, different devices, different habits, and no consistent metadata.
• Storage that cannot be defended. Material held where nobody can prove it is unaltered.
• Cases and evidence living apart. The file exists, the case exists, and nothing connects them.

A microservice platform, deployable locally or in the cloud, with a hierarchy that lets a headquarters oversee connected branches while each keeps its own working scope. Around that sit organisation management, device management, evidence viewing, location linking, case management and data analysis.

Retention period by material type, who may access what, and whether the material stays on premises. Those three answers determine the deployment far more than any feature comparison, and they are the organisation’s to give — under KVKK they are also a legal position, not only an operational one.
