DW Spectrum Licenses |
|
Video from any camera in DW Spectrum can be viewed live without a license, and there are no device count restrictions. However, a license is required to record video from a device. One license provides one channel, which is the ability to record an IP video stream from an IP camera, an RTSP stream, or an HTTP link. Therefore you need one recording channel per camera.
Several types of licenses are available, including professional, edge (for ARM servers), encoder, and the others discussed below.
A trial license is a "time license" which expires after a certain length of time.
I/O Modules require a specific type of license. See "Setting Up I/O Modules".
A specific type of license is also required for Video Walls. Each license allows a Video Wall to be extended to 2 monitors. For instance, 4 licenses allow a Video Wall to be displayed on 8 monitors. See "Video Wall Management".
Licenses and Hardware ID
Every DW Spectrum license, when activated, is locked to the hardware ID of the computing device upon which it is installed. The hardware ID is a unique 34-digit identifier generated when the server is installed on a Windows, Ubuntu Linux, or ARM device. The hardware ID is based on the following:
•Motherboard
•MAC Address
After installing DW Spectrum on a server, any modification in the components above will result in a change to the hardware ID and invalidation of licenses attached to that device (see "Expired and Invalid License Keys").
To determine hardware ID
1.In the DW Spectrum Desktop client, open Main Menu > System Administration (Ctrl+Alt+A).
2.Go to the License tab.
3.Select a license attached to the server for which you want to see the hardware ID.
4.Click the Details button.
5.The License Details dialog that opens will display the License Type, License Key, Hardware ID, and the number of archived streams allowed on that device.
6.To copy the license information press the Copy to Clipboard button.
Note: Mobile and server web clients do not have the ability to locate licensing information.
