VMS is a layer above recording itself: it handles large camera counts, user roles, centralisation across multiple locations and integrations (ACS, PZTS) and advanced features such as analytics.
What VMS typically adds
- Manage Permissions: who sees which cameras and who can export the recording.
- Events and Workflow: alarm → automatic opening of the relevant camera → incident report.
- Scaling: load distribution on multiple servers, centralization across locations.
