An illuminated sign for providing a warning that an area adjacent the illuminated sign is within a field of view of an audio/video (A/V) recording and communication device. The illuminated sign may include a front panel having translucent portions and opaque portions, and an illumination source located behind the front panel. The illumination source illuminates the front panel such that the opaque portions block transmission through the front panel of at least a portion of the light from the illumination source to provide the warning that the area adjacent the illuminated sign is within the field of view of the A/V recording and communication device.

A designed sign system 101 including: an image projector 2 for projecting an image constituted of a still image and/or a dynamic video; a projection screen body 1a for displaying recognizably by reflecting a projected image from the image projector 2; and a design part 10 formed into a shape displaying a character, a figure, or a pattern by partially providing on a projection surface side of the projection screen body 1a; wherein the design part 10 has a translucent layer 10a that diffuse reflecting a part of light received on a front surface side and transmits a remaining part, and has an opaque layer 10b that reflects remaining light transmitted on the back surface side. Thus, a designed sign system that can produce luxury feeling and has high designability may be provided.
