A system is provided for testing and enhancing the alertness of operators who monitor video surveillance imagery. Alertness is tested by displaying any of a variety of visual elements on top of or near the video imagery, and receiving input from human operators in response to the visual elements, via one or more input devices. The system further allows for economic management of human operators by transmitting imagery from many video sources to any number of operators. Video feeds are automatically switched, via software, away from an operator who wishes to take a break or has poor alertness. In this fashion, the system maximizes operator vigilance while also maximizing workflow for all available operators.

Disclosed herein are systems and methods for facilitating the usage of an online workforce to remotely monitor security-sensitive sites and report potential security breaches.In some embodiments, cameras are configured to monitor critical civilian infrastructure, such as water supplies and nuclear reactors. The cameras are operatively connected to a central computer or series of computers, and images captured by the cameras are transmitted to the central computer. After initially registering with the central computer, Guardians "log on" to a central website hosted by the central computer and monitor the images, thereby earning compensation. In one embodiment, images of"no-man" zones--areas where no humans or vehicles should be present or monitored--are sent to Guardians for a simple determination of whether or not a human exists in the picture. Site owners compensate the operator of the computer system for this monitoring service, and the operator in turn compensates Guardians based on, for example, (i) the amount of time spent monitoring, and/or (ii) the degree of a given Guardian's responsiveness to real or fabricated security breaches.Among other things, systems and methods are disclosed herein for facilitating (a) the registration of monitored sites, (b) the registration of Guardians, and (c) the management of monitoring sessions, including the routing of real and fabricated images to Guardians, the rating of Guardians, and the compensation of Guardians. Many additional and alternative embodiments are contemplated, including the following example of one embodiment.
