VEHICLE, SECURITY CONTROL METHOD FOR VEHICLE, AND STORAGE MEDIUM STORING PROGRAM USED FOR SECURITY CONTROL FOR VEHICLE

A security system includes a camera, an illuminator, and a controller. The controller determines whether a first condition is met. The first condition includes a requirement that a moving object has been detected within a first range while a vehicle is parked. The controller determines whether a second condition is met. The second condition includes a requirement that the moving object has been detected within a second range, which is narrower than the first range, while a vehicle is parked. The controller is configured to change one or more controls selected from a control of determining whether to perform recording with the camera, a control of turning on or off the illuminator, and a control of an illuminance of the illuminator, between a state in which the first condition is met but the second is not, and a state in which both the first and second conditions are met.
