ABSTRACT:
The invention relates generally to the field of warning signs intended to alert one of presence of an animal and intruder deterrence. More specifically, the invention integrates an adjustable motion detector, a warning sign, a light source aimed at the warning sign, an audio announcement and a replica of an animal or other image with another light source for its illumination. The motion detector senses the presence of a person and sends an activation signals to the audio and light sources. The first light source illuminates the warning sign, while the second light source illuminates the replica of an animal or other warning image, adding a sense of a realistic warning to a casual passer-by and a threat to the intruder.
