Navigation:  Working with Nx Witness > Obtaining and Activating Nx Witness Licenses (Admin Only)

Nx Witness’s license policy is quite simple. Each Camera requires License. The application has no camera count restrictions.

The License allows viewing and recording of a single Camera. Cameras can be viewed live without Licenses allowing for an unlimited number of Cameras to be connected and viewed live at no charge.

Note: If recording is enabled for Camera License is considered used even if recording is not performed (icon in Tree). Recording is required to capture Motion Detection and Input Detection events on Camera.

For instance, the following screenshot illustrates the situation that all Cameras are offline and not recording. However recording is enabled on four Cameras (marked by ):

In this case 4 Licenses are being used.

See also "Setting up Recording Schedule".

Additionally there are Video Wall Licenses. Each one allows controlling video wall from a single computer (one session) or extend Video Wall on 2 displays. For instance 4 licenses allow user to display Video Wall on 8 monitors and control it from 4 clients concurrently.

Nx Witness comes with four Trial Licenses automatically (do not allow Video Wall feature). Trial Licenses are active 30 days only.

IMPORTANT: In Multi Server System Licenses are activated on a certain Server (the one Client is currently connected to - icon). If this server is offline, those licenses  will be invalidated until the server is back online. If licenses are activated on different servers, they will be combined if those servers are merged into a single system.
