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, use “WitnessAdmin” as the username 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.

Aligning the Radar and Camera

1. Position and level the two surveyors’ tripods, with the radar sensor and the camera mounted on them, so that their centres are exactly 3m apart. The camera should be to the right of the radar, relative to where you will be positioned for the demonstration. 
2. Set the height of the camera to approximately 1.8m above either the ground level, or the level on which the people you want to detect will be walking. 
3. Set the radar to be 1.8m – 2.0m above the ground (and no more than 4.0m).
4. You now need to carefully align the zero points of the radar sensor and camera, starting with the radar. Turn the radar so that its flat panel (of the blue base where the connectors are located) points directly at the camera. You can use simple triangulation to achieve this:
5. Use a tape measure (with mm markings) to measure from the centre of the camera, first to one corner of the radar’s flat panel and then the other – these need to be as precisely the same as you can make them.
6. Rotate the radar until A=B and test by moving the tape measure from one corner of the flat surface to the other, making slight adjustments in the radar’s rotation until the A and B lengths are exactly equal.
7. Secure the radar to the tripod in this position so that it cannot move.
8. On the Supply unit, switch on only the Ethernet Switch Power and Camera Power.
9. You now need to align the camera with the radar. First you need to ensure the camera is in its pre-set home position, which will indicate its zero point for alignment. 
10. This camera, like many others, will return to its last position on start-up, not the stored home position. The alignment process requires the camera to be at its home position, which is factory set to the absolute 0,0 position. Setting the camera to its home position requires logging into the camera web interface using Internet Explorer. It must be Internet Explorer, as the camera uses an Active-X plugin which only works in Internet Explorer. 

11. Open Internet Explorer and enter the camera URL: http://192.168.0.2. You should see the 360 Vision login page. 

    After the camera is powered on you will need to wait a minute before the web page is accessible.

12. Log in using the username: admin and the password: 9999 
13. In the menu on the left side, click "Settings" and then click the “Advanced Features” option. You should see a page similar to this:
14. Click the “Preset” option located on the left side of the main section and choose the entry “94 : Home” from the resulting drop-down list and then click the “Seek Preset” button. Do NOT click the “Define” button.
15. Using GPS, Google Earth or a smartphone, get the longitude latitude coordinates for somewhere roughly in the centre of the demonstration site.
16. If you haven’t already done so, login to Sentinel, as discussed on page 8.
17. Once logged into Sentinel, ensure the selection/information panel on the right side of the window is open. If necessary, click on the pop-out tab on the right side of the screen. 
18. If the video viewer is not already open, follow these instructions:
    1. Select the Objects tab at the top of the selection panel.
    2. Expand the Video Viewer menu item by selecting the grey arrow to the left.
    3. Double click “1: Video”, which will open a window displaying the view the camera is seeing.
19. Loosen the camera on the tripod. Carefully rotate the whole camera by its base (NOT the upper part of the camera) until the radar appears dead centre left to right in the view. Don’t worry about the height, unless you can’t see the radar, in which case, adjust the radar height, or centre on tripod you’re using to support the radar.
20. The radar and camera are now aligned, re-tighten the camera to the tripod.
21. The camera and radar sensor are now aligned.
