Artist Dries Depoorter’s Jaywalking is an interactive installation that displays live surveillance footage of streets in various countries. Surveillance webcams capture footage of crosswalks and identify jaywalkers. From the monitor, visitors are given a choice as to whether or not they want to press a button that emails screenshots to local police stations. The work thus presents audiences with a moral dilemma. The ensuing interactions convey a complete disconnect between the surveilled and the installation viewer in charge of their fate.

Prague-based artist Jakub Geltner flips the viewpoint of standard surveillance equipment. Nest positions surveillance equipment such as video cameras and satellite dishes in congested flocks. Located at beaches, elementary schools, buildings, and bridges, amalgamations of up to twenty or so devices are placed within extremely close proximity to each other, pointing every direction. The installations suggest the spreading of an infection or rash, reminding us that in a sense, we are never out of the line of sight; we continually are being watched even when we do not notice.

The artist tapped into Seattle's surveillance systems by finding the feed of the footage buried in code. This offered him access to a continuous stream of video captured by the city's numerous surveillance cameras. “I found it pretty strange, that the police were sharing all this data to the general public,” he claims. “I had to show what you could do with this… You see just how much surveillance there really is.”
Exploring the medium since the late 1960’s, Steina and Woody Vasulka’s inventive exploration of the new technology coined them as the pioneers of the video arts. The artistic married pair found their inspiration with experimentation of the technology of the moment and social issues of their time. In 1976 Steina (who only goes by her first name) brought her work Allvision to life, born from her research of perception. The installment bears two cameras facing each other on a horizontally rotating axis, in the middle stands a mirrored sphere. The two cameras, on a turntable, slowly orbit the mirrored sphere. Each camera visualizes one half of the reflected space, making the whole space observable as both cameras’ visual were transmitted to four monitors.
