The invention relates to a face recognition device with strong adaptability for vehicle access. The device includes a housing, a light supplement assembly and two close mechanisms. The light supplement assembly comprises a rotating shaft, a switch component, a complementary light module, two support assemblies, two lampshades and a number of beads. Each support assembly includes a vertical bar anda cannula. The light supplement assembly includes a lamp tube, a power supply and a regulation unit. The switching assembly includes gears, a rack, a translation unit and an upright plate. Each closure mechanism comprises a fixing plate, a hinge assembly, a baffle, a first motor, a bearing, a first drive shaft, moving blocks and struts. The face recognition device with strong adaptability for vehicle access facilitates the camera to take clear images in a dim environment through a light compensation mechanism, and can easily carry out accurate face recognition. Moreover, when the light is strong, the baffle can block the opening through the closing mechanism, the camera is prevented from being damaged, the safe operation of the equipment is protected, and the practicability of the equipment is improved.
