Abstract
A television-camera is used to obtain a video image of an area to be monitored, the video image being displayed on the display screen of a television receiver. A light pin is used to set plural display points on the display screen so as to define a specific area within the video image. By comparing density levels of successive frames of the video image, a moving object is detected. An alarm is generated if a detected moving object contacts a set number of the display points set using the light pin. Also, by employing two or more television-cameras oriented at different angles with respect to the area to be monitored, and by setting respective sets of display points for each the thus obtained video images, reliability of the alarm detection can be enhanced.
