A vehicle interior is monitored by storage of sample signals in a memory of a computer and comparison of at least one stored sample signal with a signal picked up on a detector of sound waves from the interior of the vehicle. An identity or similarity test is conducted by the computer and an alarm device is triggered when the predetermined degree of similarity is reached to signal an incursion.
