Wifi Eyes

Panoramic Wifi Camera

The Wifi Camera is a camera that takes "pictures" of spaces illuminated by wifi in much the same way that a traditional camera takes pictures of spaces illuminated by visible light.


The very first camera we built, as exhibited in Riga for RIXC/Waves in 2006.


"The Panoramic Wifi Camera takes ‘pictures’ of spaces illuminated by wireless radio signals, in much the same way that a traditional camera takes pictures through visible light. 
In effect, it is a camera which captures the invisible. 
Wireless radio networks are increasingly part of our daily lives throughout the developed world. The camera reveals the topology of this electromagnetic ecology, or ‘Hertzian space’, showing that even our own bodies cast their ‘shadows’. 
Wifi uses wireless radio signals in the of 2.4 Ghz range which behave similarly to light waves, in that they are reflected off almost all solid objects. When we perceive colours, we see the light that is reflected off an object into our eyes.." transmediale.de

Single Pixel Wifi Camera
The single pixel wifi camera is built from a directional antenna made of wasabe pea cans, which have the perfect diameter to act as a highly directional wave guide antenna for Wifi radio waves, which have a wavelength of 12.5 cm. wificamera.propositions.org.uk

Wifi Camera Obscura. First draft 02 2006
 

"The camera obscura, just like a large pinhole camera, is a dark room that has one wall punctured by a small hole. Light comes through the hole and projects an inverted image of the exterior scene against the opposite wall..."  wificamera.propositions.org.uk
