• During the upgrade from version 2.6 or lower no servers come up.
• In fact, you can see that all of them are running and allow to connect directly with a browser or via the Spectrum Client. All other servers at that moment are shown as "offline" in the resource tree.
• If you check "System Administration" menu(Ctrl+Alt+A), "Routing management" tab and click any offline server you'll see all network addresses with "0" port values.

1. If you have autodiscovery option disabled -- please turn it on till servers find each other(typically happens within seconds). To turn it on:
   - Go to "System Administration" menu(Ctrl+Alt+A)
   - At "General" tab, "System Settings" section find "Enable cameras and servers auto-discovery" checkbox and fill it in
   - Click "OK" or "Apply" to save changes
   
   
2. If you already have auto-discovery enabled but there's still no communication and servers have "0" port values at the "Routing Management"  -- likely you have multicast connections disabled on the networking level. 
   No worries, there is an easy way to manually modify this port information:
   - Go to "System Administration" menu(Ctrl+Alt+A)
   - At the "Routing Management" tab click any "offline" server
   - Click "Add" button at the right panel, "Enter URL" dialog window will pop up
   - Input network interface address which is used for connection to other servers with correct TCP port specified to the URL bar.
3. Click "OK" or "Apply" to save changes. Typically it takes seconds to get servers back online.

If Spectrum cannot add the Compressor via Auto-Discovery or Manually using port 8080, then try the following steps in the order presented:

2. ·         Can you ping the compressor from the Server?
3. ·         Can you access the compressor from the Servers browser?
4. ·         Check Compressor’s firmware is on the latest firmware.
5. ·         Power cycle the unit.
6. ·         Factory Default unit.
7. ·         Re-install the firmware.

• Registered cameras will go offline upon firmware upgrade
• New cameras will not be properly discovered

How to solve this problem?

1. Re-enable ONVIF Protocol
   • Navigate to your Hikvision camera web administration interface and look for the Integration Protocol section of the settings web-page
   • Click on the Enable ONVIF checkbox
     
   • Also, make sure to enable Hikvision-CGI

1. Add a New ONVIF User
   • While still in the affected camera's web administration interface navigate to the camera's Configuration -> System -> Users menu and add a new ONVIF user (up to 32 per device). 
   • Make sure the user has Administrator rights.
2. Update Camera Authentication
   • Right-click on the affected camera(s) in Spectrum and open the camera settings dialog.
   • Update the Login and Password for each affected camera. 
     • Note: If you update all Hikvision cameras with the same username and password you can update the Login and Password for all affected cameras at the same time by selecting all affected cameras and then opening the Camera Settings dialog.

More than one item can be added to a layout simultaneously regardless of their source (live cameras, local video, images, etc.).

Spectrum allows up to 24 items to be displayed on clients running on a 32 bit OS and 64 items on a 64-bit operating system.

To add item(s) to a layout, select from one of the following:

-          Double-click on the item in Resource Tree

-          Select Open from Context Menu in Resource Tree.

-          Multiple items can be selected and added (Ctrl + Shift and select the desired items).

-          Drag and drop from Resource Tree

-          Ctrl + drag and drop items onto a scene to duplicate. To avoid duplication, release Ctrl and hit Esc while holding the left mouse button.

-          Hold Ctrl or use a mouse to select multiple items on the scene. To select all items, use Ctrl + A. 

New items will automatically occupy all available space. The aspect ratio of grid cells will automatically adjust to the aspect ratio of an existing item to occupy the space.

To open items directly from a new tab:

-          Select desired item(s) from Resource Tree and select Open in a new tab from Context Menu

-          Drag the selected item(s) from Resource Tree and drop them to Tab Navigator

-          Ctrl + drag and drop items from scene to Tab Navigator (Multi-Selection can be applied). To prevent duplication, release Ctrl and hit Esc while holding the left mouse button. 

How to configure a layout using search:

-          Create a new layout. 

-          Enter any three consecutive characters into the search box. The results will appear automatically.

-          By adding or deleting keywords from the search box, the items on the scene will adjust.

-          Save the configured layout if desired

While operating your client, you can press F1.  This will display your client version, as well as the server version if you are connected to a server.

• DW Cloud connected systems can reset their password at any time by using the built-in password reset function.

Server and Desktop Client are stopped right after start. In Windows "Event Viewer" you can see that application is killed by Operating System due to libeay32.dll.

libeay32.dll is a dynamic library, part of OpenSSL which is open source solution for SSL/TLS connections. It is used for any Nx Client and Server secured connections, that is why it is so important.

How to solve this problem?

You'll need to replace your libeay32.dll library.

1. Download an updated version of the libeay32.dll library.
   • libeay.dll for 32-bit Windows
   • libeay.dll for 64-bit Windows
     
     
2. Replace the existing libeay.dll file (located in your application directory) with the newly downloaded libeay32.dll file. If you have ever updated refer to Desktop Compatibility bullet point, the library should be put to every copy of Desktop Client currently installed.
3. • Spectrum Desktop Default Location 
     • C:\Program Files\\Digital Watchdog\DW Spectrum\Client\<Version_Number>\libeay32.dll
       
       
   • Desktop Compatibility Mode installations(installed after any update)
     • C:\Users\<USERNAME>\AppData\Local\Digital Watchdog\client\digitalwatchdog\<Version_Number>\libeay32.dll
       
       
   • Media Server
     • C:\Program Files\Digital Watchdog\DW Spectrum\MediaServer\libeay32.dll
       
       
4. Start Spectrum (Client or Server)

Devices that operate with ONVIF Profile S will automatically be detected by Spectrum and displayed in the resource tree.  Real Time Streaming Protocols (RTSP) and HTTP streams can also be added manually to Spectrum. You can also use our Spectrum Compatibility List to see if your camera is supported.
