Abstract: 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 b 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.

Abstract: An anti-vehicle-thief apparatus registers specific ID codes of a plurality of keys, and determines validity of a key, for example, in accordance with an operation of the key 1 including a transponder having one of the registered specific ID codes. The anti-vehicle-thief apparatus registers a code specific to the key and confirms an operation in which an ignition switch is turned on and off five times by using the key, where this operation is for changing the ID codes specific to the plurality of keys registered in EEPROMs. After the confirmation of the operation, ID codes specific to a plurality of new keys are successively registered, thereby preventing a third person from using the old keys, as well as making registration of the ID codes specific to the new keys easily.
