An alarm device executes first alarm processing when an alarm target satisfies a first alarm condition, and second alarm processing when the alarm target satisfies a second alarm condition. In a first alarm state where the first or second alarm processing is executed upon detection of the alarm target, when a second object is detected as an alarm target different from a first object that is an alarm target of the first alarm state, the alarm device does not execute the first alarm processing for the second object as the alarm target even when the second object satisfies the first alarm condition, determines priorities of the second alarm processing for the first object and the second object when the second object satisfies the second alarm condition, and executes the second alarm processing for the second object when the priority of the second alarm processing for the second object is higher.
