<p>The invention relates to an anti-theft alarm system which comprises a detecting sensor (2), detecting electronics (8; 6, 9, 11) and alarm means (4, 6, 8) provided with a sound signal device (4). The detecting sensor (2), detecting electronics (8; 6, 9, 11), and alarm means (4, 6, 8) are connected to a portable digital information medium, which may be a telecommunication means (1) or a pocket computer. Especially when connected to a mobile phone, the anti-theft alarm system can be connected to use at least partly the same alarm means (6, 4) as the mobile phone uses for alarming of incoming telephone calls. The anti-theft alarm can be distinguished from other alarms by means of a different alarm sound.</p> |
