Monitoring system for vehicle

An all-directional monitoring camera (10) mounted, straight or with inclination forward and/or laterally outward with respect to vertical direction, on a bumper (1) on a side remote from a steering wheel (2) comprises a reflecting mirror (13) and a camera (14) operative to image a peripheral scene reflected by the reflecting mirror (13) that are enclosed within a casing (11) having a transparent wall (12) surrounding entirely the reflecting mirror (13). The monitoring camera (10) is movable between a working position where the reflecting mirror (13) is positioned right above an outermost end (1a) of the bumper (1) so as to include an outermost end profile of the bumper in a field of view and a hidden position where the monitoring camera (10) stays in hiding in the vehicle body. An image formed by the monitoring camera (10) displayed on a monitor display (20) includes a break line (Lz) representing the outermost end profile of the bumper (1).
