1. An access control reader comprising:a casing integrating a base presenting a main wall provided for a fixation on a support and a facade mounted on said base, and
a detection device for detecting an opening of the casing,
wherein the base and the facade include complementary guides shaped to guide the facade in a tilting motion relative to the base when opening the casing starting from a closed configuration in which the facade is fastened and folded over the base up to an open configuration in which the facade is spaced away from the base and is inclined with respect to the main wall at a predefined non-zero angle, and
wherein the detection device is mounted on the facade so as to detect the tilting motion of said facade.
