The best enterprise video management systems score high on five criteria: scalable architecture, centralized multi-site management, integrated AI analytics, built-in cybersecurity, and open hardware compatibility. Nx Witness Enterprise, built on the Nx EVOS platform by Network Optix, is built around all five.
Use the checklist below to evaluate any platform, including Nx Witness, against the same standard.
Enterprise VMS evaluation checklist
| Criteria | What to look for | Nx Witness Enterprise |
|---|---|---|
| Scalability | The ability to unify a large number of geographically separate servers | Server-Hive per site, plus a Cloud Organization layer for unlimited sites |
| Centralised Management | One interface for system health, users, and footage across every site | Single interface across all connected sites |
| AI Analytics | On-device or edge processing for object detection and classification | Nx AI Manager, integrated directly into Nx Witness |
| Security | Native encryption, authentication, and audit logging | TLS 1.2+, LDAP, audit trail, ISO 27001, SOC 2 Type 2 |
| Openness | Broad third-party camera support | ONVIF compatibility across major manufacturers |
Why each criteria matters
Scalability
Every VMS architecture has a ceiling. A single Nx Witness site is a Server-Hive of up to 10 Nx Media Servers, each supporting up to 256 video sources, for a per-site cap of 2,560 video sources. Within that ceiling, servers sync configuration automatically and transfer cameras between peers on failure, so recording continues without a gap.
Nx Witness Enterprise removes that ceiling at the multi-site level through Nx Cloud's Organization layer. An Organization connects an unlimited number of sites under one entity, sharing layouts, notifications, and user permissions across all of them. That's the mechanism for scaling past a single Hive: administrators manage every site from one interface instead of standing up disconnected systems as they grow.
Centralised Management
Administrators need one interface for system health, user access, and video retrieval across every site. The Organization layer delivers this in a single view, whether that covers one site or hundreds.
AI Analytics
Nx AI Manager processes video on-device and at the edge, so analytics run without needing to route footage through the cloud. That keeps latency low, keeps data inside the organization's infrastructure, and surfaces results directly inside Nx Witness.
Security
Nx Witness encrypts inter-application communication with TLS 1.2 or higher, supports LDAP with certificate validation, and logs a searchable audit trail by default. Network Optix holds ISO 27001 certification and has completed SOC 2 Type 2 audits, with a NIS2 assurance statement available at Trust.NetworkOptix.com.
Openness
Nx Witness supports ONVIF-compliant cameras across a wide range of manufacturers. Existing camera investments carry forward into a new deployment.
FAQ
How many cameras can an enterprise VMS support? A single site is capped by its Server-Hive: up to 10 servers and 2,560 video sources. Nx Witness Enterprise scales past that by connecting sites into a Nx Cloud Organization, which supports an unlimited number of sites under one administrative view.
What's the difference between a VMS and an NVR? A network video recorder (NVR) is hardware built to record from IP cameras. A VMS is software that manages recording, analytics, access, and integrations across a broader system, typically running on standard server hardware.
Does an enterprise VMS require cloud hosting? No. Nx Witness runs on-prem, edge, cloud or hybrid. Nx Cloud adds remote access, monitoring, and the Organization layer for multi-site scaling.
What is a Nx Cloud Organization? A Cloud Portal entity that connects an unlimited number of Nx Witness sites, sharing layouts, notifications, and user permissions across all of them from a single administrator view. It's available to Nx Witness Enterprise sites connected to the Cloud Portal.
