Abstract

An intrusion detection apparatus and method thereof are provided. The intrusion detection apparatus includes a status detection device, a front-end signal processor, a delay device, and a signal sampler. The status detection device is configured to generate an indicating signal according to an opened status of the case. The front-end signal processor receives the indicating signal and performs a noise filtering function on the indicating signal so as to generate a processed indicating signal. The delay device delays the processed indicating signal to generate a delayed indicating signal. The signal sampler samples the processed indicating signal to generate a detection result according to the delayed indicating signal.
