<p>In the conventional answer phone, the so-called "answer phone mode" is extended to "an anticrime answer phone mode". In this mode, each time a predetermined time has elapsed or immediately after an intruder into home is detected, an audio as follows is reproduced: "Trururu, trururu, trururu, ...I am out now. Speak after the transmission sound. Peee ... Hellow, this is Father speaking. I have now arrived at the station. I'll be soon at home". If any intruder is present and hears this, the intruder judges that a family member will soon be home. The intruder probably runs away without stealing anything. That is, by reproducing a message that a family member will soon be at home as if the message were made by an external call, an alarm to an intruder can be generated and it is possible to prevent theft by the intruder.</p> |
