A remote breath alcohol monitor configured for capturing a facial image of an offender while the offender is delivering a breath sample, and comprising: a vent opening in the remote breath alcohol monitor disposed for receiving a breath sample in an ethanol sensor within the remote breath alcohol monitor; at least one circuit board assembly within the remote breath alcohol monitor arranged for processing the output of the ethanol sensor to determine a breath alcohol content; a camera connectable to the at least one circuit board assembly arranged for capturing a facial image of a user; a wireless cellular phone module embedded in the at least one circuit board assembly and arranged for sending the breath alcohol content and the facial image; the at least one circuit board assembly being arranged to perform a facial match on the facial image compared to an enrollment image, and a breath tube connectable to the vent characterized by : a pressure transducer within a fuel cell assembly with tubing arranged to measure that the offender has blown hard enough and long enough for the breath sample to be valid; in that the breath tube is flat in cross-section thus to prevent insertion of a smaller round tube thereinto and preventing a user from tilting his/her head too much from side-to-side, that is, no more than about 10°; and in that the length of the breath tube is such as to achieve a focal length between the camera and the user's face. a vent opening in the remote breath alcohol monitor disposed for receiving a breath sample in an ethanol sensor within the remote breath alcohol monitor; at least one circuit board assembly within the remote breath alcohol monitor arranged for processing the output of the ethanol sensor to determine a breath alcohol content; a camera connectable to the at least one circuit board assembly arranged for capturing a facial image of a user; a wireless cellular phone module embedded in the at least one circuit board assembly and arranged for sending the breath alcohol content and the facial image; the at least one circuit board assembly being arranged to perform a facial match on the facial image compared to an enrollment image, and a breath tube connectable to the vent characterized by : a pressure transducer within a fuel cell assembly with tubing arranged to measure that the offender has blown hard enough and long enough for the breath sample to be valid; in that the breath tube is flat in cross-section thus to prevent insertion of a smaller round tube thereinto and preventing a user from tilting his/her head too much from side-to-side, that is, no more than about 10°; and in that the length of the breath tube is such as to achieve a focal length between the camera and the user's face. a pressure transducer within a fuel cell assembly with tubing arranged to measure that the offender has blown hard enough and long enough for the breath sample to be valid; in that the breath tube is flat in cross-section thus to prevent insertion of a smaller round tube thereinto and preventing a user from tilting his/her head too much from side-to-side, that is, no more than about 10°; and in that the length of the breath tube is such as to achieve a focal length between the camera and the user's face. <EOS>
