Is the location of my window suitable for Telraam?
1. On the participation form, you are asked to upload a picture.
The purpose of the photo upload on the participation form is to check whether your location is suitable for Telraam. Is the roadway and/or footpath visible? Is there a balustrade that disturbs, a flysheet, a shutter or a tree that obstructs the view?
We ask you to take a picture of the street from the window (1st or 2nd floor), just as you would place a Telraam against the window. This means perpendicular to the street and not slanted. If you want to place the Telraam on the second floor, we ask you to take a photograph from the second floor. Sloped windows or skylights do not qualify to hang a Telraam.
- You have a window on one of the floors (no ground floor window), minimum height is 3 meters. Preferably higher.
- Maximum distance from window to street is about 15 meters.
- Avoid locations that have fully stand-still traffic for over 30 seconds, in particular near traffic lights or busy intersections
- Your Telraam is not too close to the road. 'Too close' means that vehicles the size of a van (and larger) do not fit in the field of view of the camera. This may be the case, for example, for one-way streets where there is no footpath on either side. Think of a street narrower than 5 meters.
2. You received your Telraam and wish to install it on your window.
All the conditions mentioned above have to be respected. During the installation process, you'll have to check if the image you receive from your camera do respect these conditions.
- You have your own WiFi connection to which your Telraam device will be connected. This way the traffic data can be forwarded to the database. (So wifi access in the room where you want to hang your Telraam)
- Finally, you also need a power outlet, because your Telraam device needs power.
Here are some examples of good images:
And now some examples of "bad" pictures:
Remember: That window should be on the street side and have a clear view on the street: no tree, no plant or pole in front of it, no fly window in front of it...
- The flag moving on this picture on the other side of the street will interfere. Moving objects will interfere with the recognition of moving vehicles.
- The fly window in front causes poor visibility.
- The tree in front of the window is problematic. Again, if it's windy, the movement of the tree branches will interfere.
- The window must be perpendicular to the street. That is not the case here:
