Network Configuration

The demonstration equipment is pre-configured as follows:

  • Subnet:   192.168.0.0/24 (mask = 255.255.255.0)
  • Radar sensor:   192.168.0.1
  • Camera:   192.168.0.2

Give your computer another address within the same subnet, e.g. 192.168.0.5.
If you are not sure how to do this, then either:

You may “multi-home” your network configuration, allowing your PC to connect to another network, such as one with internet access, at the same time. Internet access is required to download a map image from Google or Microsoft. If the location of the demonstration is known beforehand, it is advisable to download a map and locate it within Witness before setting off. If on the other hand, the location is not known, we would suggest you take a smartphone with you, which can be tethered to your laptop allowing you to download a map once the demonstration location is known, assuming, of course, that you have mobile data access at the demonstration site.

Installing Witness

  1. Download the latest version of Witness from here.
  2. Ensure that the Microsoft .NET and Visual C++ 32 and 64bit prerequisites have been downloaded from the Microsoft website and have been installed on the system.
  3. As an Administrator, run the downloaded Witness executable. 
  4. When asked what type of installation is required, choose the “Demo” option:



  5. Continue through the setup wizard by clicking Next > to choose all of the default options. Finally click Finish on the last page.
  6. Wait a moment to allow the programme services to start-up before opening Sentinel.

Logging In

  1. Start Sentinel by double clicking the Sentinel icon on your desktop. 
  2. In the logon dialog, replace “Navtech User” with “WitnessAdmin” (you will only need to do this the first time) and use the password “Navtech Radar.”  Note the capitals, space and full stop/period) the password is case sensitive, the username is not. 
  3. Once logged in you will see: A square detection area coloured blue and inside this you will see symbols representing the radar and camera.
  4. Enter Admin mode by simultaneously pressing Crtl+Alt+F5.

If this doesn’t work, then it is probably due to the Intel Graphics Hot Keys being enabled. To cure this: From the system tray (bottom right) select Intel HD Graphics then Graphics Options > Hot Keys > Disable. When it works, the word “Admin” (in red) should appear near the top right in the Sentinel title bar.
