When setting up the DW Spectrum Server, the host computer relies on its networking setup to communicate with the connected security devices over the local network. 

For this to work, the DW Blackjack unit’s network settings will need to be configured to identify with the camera network, as well as with the router and other local devices.

This article will outline a basic network setup for DW Blackjack Servers using the Ubuntu/Linux OS.

Supported/Affected Devices

  • DW Blackjack Bolt (Ubuntu/Linux)
  • DW Blackjack Cube (Ubuntu/Linux)
  • DW Blackjack P-Rack (Ubuntu/Linux)
  • DW Blackjack E-Rack (Ubuntu/Linux)

Setup Process

  1. Connect network cables to the Server’s Network Interface Controller (NIC).  It is recommended to connect the PoE switch directly to the Server, to minimize bitrate ‘bottlenecks’ between the cameras and the Server.

If you are using a DW Blackjack Series unit as the Server, there may be two NIC cards (see sample image).

Note:  If you are using a Custom Built Server (not manufactured by Digital Watchdog), and have not yet added DW Spectrum, please read Installing DW Spectrum (Ubuntu).

  1. Open the Network tool, located on the Desktop of the Blackjack unit.

Select the Wired option that represents the camera network (PoE Switch) connection, then select Options.

Note:  Alternatively, you can open the Network tool by clicking on the connections icon, then selecting Edit Connections.

Select the Wired connection option that represents the camera network (PoE Switch) connection, then click Edit.

  1. Click on the IPv4 Settings tab.

Change the Method (connection type) to Manual, then click the Add button.

  1. Assign an IP address to the camera network NIC card.  This address will be used to identify the computer within the camera network. 

Note:  It is important that the Server is not assigned to an IP address that is also being used by any other devices within the network.

Additionally, the camera NIC’s IP address scheme must match the camera network’s sub-network IP address scheme.

  1. Keep the Netmask as

  1. Leave the Gateway field blank.  The Gateway information is not necessary for communicating with the camera network only.

Note:  If the NIC is communicating through the router, use the Gateway address of the router.

  1. Click Save to apply the settings.

Cameras assigned to IP addresses that also identify with the camera subnetwork, and that are connecting through the camera network NIC, should now be able to communicate and be added to DW Spectrum.

Note:  If you still need to assign an IP address to a camera, please read Assigning A Static Address To New Or Defaulted Cameras.
