A method and apparatus with an integral security system. The apparatus includes an electronic device for sending signals to a remote station, such as a pre-determined telephone number, at spaced-apart intervals of time. The signals include identifying indicia for the apparatus. The identifying indicia may be a characteristic serial number. The apparatus may include a computer and software for providing the signals to a communication interface on the computer. Preferably the software is programmed on a memory device for the computer at a location not normally accessible to operating software for the computer such as a boot sector of a disk thereof. The system should contact the remote station without visual or audio signals apparent to the user. The remote station is able to determine the identification and location of the computer from the signals received including the identifying indicia and caller I.D. signals provided by a telephone company.
