Nx Witness User Manual
Nx Witness comes with four trial licenses. A trial license is active for 30 days.
IMPORTANT: Licenses for Servers in a multiple Server System are activated on the Server to which the client is currently connected. If this Server is offline, those licenses will be invalid until the Server is back online.
Note: Licenses that are activated on different servers will be combined if the servers are merged into a single System.
To Activate a Free License
To get additional licenses, contact your local Nx Witness reseller or Network Optix customer service.
Desktop Client
1.Open Main Menu > System Administration and go to the Licenses tab.
2.Click Activate Free License.
1.Open Settings > Licenses.
2.Click Activate Free License.
Note: You will be warned when a Free License is about to expire.
To Activate a License over the Internet
The server the client is connected to (as indicated by the current server 
icon in the Resource Panel) will have the license key bound to it. If it is necessary to activate the license key on a different server, disconnect and connect to a desired one. If Nx Witness is not connected to the Internet, then licenses can be activated offline.

2.Go to the Internet Activation tab.

To Activate a License (Trial or Commercial) Offline
In situations where an Nx Witness System is installed on a device that does not have Internet access, users will be required to perform an Offline (or Manual) license activation. Launch the Nx Witness Client and connect to the Server on which you wish to do an Offline (manual) Activation. The Nx Witness Desktop Client is required – mobile or Web Admins do not have the ability to locate licensing information.
1.Go to Licenses tab in System Administration.
2.Go to Manual Activation tab.
3.Press the Copy button to copy the hardware ID.
4.Email Network Optix customer service to request an activation key, include the Hardware ID and License Key you received in the Email.
5.As soon as you receive the activation key, click Browse to import it to the target computer.
To Export a List of License Keys
It is possible to export a list of license keys to a CSV or HTML format file. It may be necessary, for instance, if re-activation is needed. To do so, click on Export (near the upper right corner) and select the target file.
Nx Witness allows for license deactivation as well. See "Expired and Invalid License Keys".
Note: When recording is enabled for a device, the license is considered in use even if the device is not currently recording (as indicated by the empty circle
icon to the left of device in the Resource Panel).
Insufficient Licenses Available
An error message or information banner will be presented when there are insufficient licenses to support the selected configuration.
