The artist Julia Scher is known for her work with surveillance technologies. In 1993, Scher’s video installation Mothers Under Surveillance was included in the exhibition “The Final Frontier” at the New Museum. A simultaneous broadcast of the gallery space is mixed with prerecorded footage of elderly women being tracked while they attend “adult day care.” By including a date and time stamp, which functions as a sign for the “reality” of these images, the two streams of images merge into a single surveilled world. Scher creates an endless loop of people watching people while being watched themselves, with the aim of making visible the invisible systems of power and control enabled by electronic technology. Mothers Under Surveillance is on view in “NYC 1993: Experimental Jet Set, Trash and No Star” through May 26.
