Sousveillance, derived from French "sous" (below) and "veiller" (to watch), is the art, science, and technologies of "People Looking at". Sousveillance does not immediately concern itself with what the people are looking at, any more than surveillance concerns itself with who or what is doing the looking. Instead, sousveillance typically involves small person-centric imaging technologies, whereas surveillance tends to be architecture or enviro-centric (cameras in or on the architecture or environment around us). Sousveillance does not necessarily limit itself to citizens photographing police, shoppers photographing shopkeepers, etc., any more than surveillance limits itself along similar lines. For example, one surveillance camera may be pointed at another, just as one person may sousveill another. Sousveillance therefore expands the range of possibilities, without limitation to the possibility of going both ways in an up-down hierarchy.

With the miniaturization of cameras into portable electronic devices, such as camera phones, there has been an increased awareness of sousveillance (more than 30,000 articles, references, and citations on the word "sousveillance" alone), and we are ready to see a new industry grow around devices that implement sousveillance, together with a new sousveillance services industry.
