Surveillance cameras are markers for the neuralgic spots of urban life, periscope-like excrescence of the underlying systems, its´ eyes mostly visible, but the processing apparatus hidden to the subject of surveillance.

 

The reactive sculpture “Nordpol” investigates this issue by creating a transparent signal processing chain.

The inputs of microphones hanging from the ceiling are transmitted to the floor, where a microprocessor calculates the position(s) of any source of noise, and turns tripod-mounted cameras in the resulting direction.

The signal processing chain is disclosed, the simple mechanics of the system can be decoded by playing with it, leaving one essence of surveillance, detached from protective architecture, its entrails spread out, fragile, nervous and image-less.
