Abstract

Independent detection and alarm device using a radar whose various elements such as regulation, amplification and alarm circuit are enclosed in a box, characterized by the fact that said box, which also encloses a transformer and a battery batteries, which makes the device eventually autonomous, is closed by a door whose front face serves as a photographic frame or advertising support that conceals the box.
