CCTV operator performance and system design

The introduction of the Rotakin test is shown to be an important step toward improving the performance of closed-circuit television (CCTV) systems. Analysis of the alarm event process calls attention to the areas of sensitivity whereby the system can fail. Reference to knowledge in the human visual performance field makes it possible to improve the images presented to the operator, thereby permitting him to do his job more easily. The addition of systems performance testing to systems specifications provides a non-altruistic motive for the pursuit of the relevant engineering knowledge
