The invention relates to an alarm which signals an incident (theft) from one mobile telephone to another, the operation of which is not interrupted even if the power supply and telephone line are cut. The invention can be used remotely to perform the following functions independently: alert the police personally, activate the panic siren and listen to ambient noise in every room. If the incident occurs in a vehicle, the inventive alarm silently signals the incident via the user's mobile telephone. In this way, the user is informed immediately of the incident and can disconnect the current in the vehicle, thereby immobilising the vehicle during the incident, activate the panic siren and listen for any type of ambient noise inside the vehicle interior. Moreover, the user can also disconnect the current and stop the vehicle immediately. The wireless telephony-operated alarm system offers improvements in relation to standard, currently-available alarms in that it requires no electricity or additional system for operation, thereby affording more benefits than other available alarms. |
