Nx Witness is Network Optix’s fast, lightweight VMS that works with any camera brand. It brings discovery, live view, recording, search, and response into one system, runs on Windows, Linux, macOS, iOS, Android, and in the browser, and grows from a few cameras to large multi-site deployments.

Key capabilities
Works with what you have
Compatible with 25,000+ devices, with cameras found automatically through ONVIF and vendor SDKs. RTSP, HTTP, and UDP streams, IoT devices, and third-party systems join the same system.
Fast search and AI
Search the archive by Smart Motion, objects, bookmarks, and date. Camera and third-party AI analytics show on the timeline and drive rules.
Shaped to your operation
Fit layouts, the rules engine, and soft triggers to how you work. Set permissions per group or user and connect LDAP.
Ready to grow
Grows from one camera to many sites. Servers keep settings in sync, and if one fails its cameras move to the others automatically.
How it works
Nx Witness has four parts: the server that works with cameras, the desktop for operators, the mobile app, and Nx Cloud for remote access.
Nx Server
The engine that finds cameras, takes streams, records, and runs rules.
- 256 streams per server
- Windows, Ubuntu, ARM
- NAS, SAN, cloud, COLDSTORE
Nx Desktop
The open-source client for live view, playback, search, and administration.
- 64 streams on one layout
- Windows, Ubuntu, macOS
- Video wall and showreel modes
Nx Mobile
Live and recorded video, and actions, from a phone.
- iOS, Android
- Smart Motion and object search
- Push notifications, soft triggers
Nx Cloud
Remote access and management with no static IP or port forwarding.
- Unlimited systems and sites
- In the browser, nothing to install
- Invite users by email
AI and analytics
From video to insight
Objects from in-camera analytics and AI plugins are marked on the timeline and feed search and the rules engine directly. Nx AI Manager runs your own AI models on many kinds of accelerators and updates them across devices remotely.
- Build rules on in-camera analytics from Axis, Hanwha, and Hikvision
- Show AI plugin objects, bounding boxes, and attributes over video
- Search by object on desktop and in Nx Mobile
- Nx AI Manager: Intel, NVIDIA, Hailo, and DEEPX accelerators
