In our first attempt with Version 1, we pictured a simple room with the WiFi router a little to the right. When we generated the WiFi image, we saw it corresponded perfectly, and showed dark spaces where the signals were weak, mostly the walls and the pole, and brighter red when the directional cantenna was towards the router.

We then tried out Version 2. Initially, the Version 2 picture (bottom left) came with a lot of black pixels, some arranged in a sort of pattern. We later realized that this was due to interferences, such as the WiFi being used upstairs, a microwave oven running, and more. We tried to cut off all interferences, turned them off, and tried taking another picture (bottom right). This time, the picture was more of what it should have been, brighter where the router was, and darker where the signals were not available (as shown with a directional cantenna).

The next picture we took was outside the room that had the router. Naturally, the WiFi signals should have been the strongest at the door, as the door was open, while the walls would have suppressed them.

When we tested the camera and generated an image, our assumptions came out true. We could notice bright red spots where the door was, while the rest were darker, very dark to the sides. That showed that the signals were passing through the open doorway, while the walls were greatly stopping the signals.

We took another picture upstairs, one floor above the location of the WiFi router. When the image was generated, it was a very dull, more towards black, image that showed us that the signals were not strong to begin with, being a floor above.

The image was able to successfully attribute the left-center position with bright red pixels, where the WiFi router was beneath us. The location of the pixels was due to the tilt of the camera, approximately 80 degrees, corresponding with the router below, accurately mapping the data to pixels on the image.

We tried out the camera at our high school, and found out that it worked perfectly over there as well.

The 90 degree angle was directly facing the router and showing bright red pixels, visually stating the strength of the WiFi signals coming from the router, while the pole on the left and the sides were darker, owing to less strong signals in those regions.

We tried to check the spread of the signals by detecting them bouncing off the walls as well. We were able to do that by placing the router next to a wall, and checking the spread of the signals in the WiFi image.

We were able to successfully see how the router was more of a darker shade, while the signals it was emitting were all around it, as shown by brighter red pixels in the picture. This showed us how the signals spread and how they were all around us, undetectable visually except by this device.
