About NoldusViso
Last updated: Nov 09, 2026
NoldusViso is a scalable audio-video recording platform for setting up and capturing observation sessions, such as usability tests, counseling sessions, and training exercises. Everything is recorded to one central location, with role-based access control and two-factor authentication to keep data secure, and a simple browser-based interface so users can get started quickly.
The platform scales from a single room with a few cameras to a multi-site, multi-room solution recording synchronized audio and video across locations. NoldusViso is built for simulation and training, counseling and psychology, human factors research, and UX research.
- Central, secure recording — no scattered files across devices
- Scales from one room to multi-site deployments
- Browser-based access for all users
This page is for behavioral researchers and lab staff who will record, review, and annotate sessions in NoldusViso.
Prerequisites
- A central computer (workstation or laptop) with NoldusViso installed. This is the only machine that needs the software installed.
- An admin must set up user roles before anyone else can work in the system. Roles include: Admin, Trainer/Researcher, Trainee/Student, and Guest.
- All users — technicians, admins, researchers/trainers, students/trainees, and guests — access NoldusViso from their own computer through a Chrome browser. No local installation is needed for them.
Important note: Role assignment is admin-only. What a user can do (recording, annotating, viewing, sharing) depends on the role the admin has assigned them. Standard role names can be changed by the technician, to better fit naming used.
Product overview
NoldusViso works around one central concept: the Scenario. Users create a Scenario either from a Template or from scratch, save and name it, then use it to start a Session — an actual recording. Sessions are captured through connected Devices and can be reviewed, annotated, and shared afterward. Multiple scenarios can be recorded at the same time, as long as they don't use overlapping devices.
Key concepts
- Template — A starting point based on a standard research set-up, with placeholders for sources, subjects, tasks, and events. Used to quickly create a new scenario instead of building one from scratch.
Scenario — A saved, reusable configuration that defines what a session records and how it can be annotated: the sources (audio, video, screen capture), the subjects, tasks, and events available for annotation. Created either from a template or fully from scratch, and can be named, copied, and shared with other users. It's the starting point for every recording.
- Subject — A person, or multiple persons, appearing in the recording.
- Task — Something that happens over a duration, e.g. writing, walking, sleeping.
- Event — Something that happens at a single point in time, e.g. an entry, an error, a hit, a cry.
- Device — A camera or microphone connected to the system and used to capture audio or video.
- Session — A single recording created when a user starts recording a scenario. This is where the actual audio, video, and annotations live. Multiple sessions can run at the same time, provided their scenarios don't share the same devices.
