Abstract: An imaging intrusion detection method combines condensing lenses with a plurality of light sources to form and illuminate a plurality of collimated light beams to a security area as dot lighting. A dot image of the security area to which the dot lighting is illuminated by an intrusion monitoring camera is obtained and stored in a memory as reference dot information. When an input image is obtained by periodically photographing the security area, dot information is extracted from the input image to compare the dot information with the reference dot information, and it is determined whether there is an intrusion in the security area according to a change of a dot based on a result of comparison.
