Biometric monitoring and camera image ID
Facial biometrics and hum tone recognition are used to identify the driver as the person providing the breath sample. When combined with the FOCUS camera, an image of the driver is taken with each critical event.
Dual event logging
Events are logged in both the handset and the ECU, enabling remote downloads while protecting the security of the event log file and enhancing anti-circumvention measures. Attempts to start the vehicle engine with the handset disconnected are detected and recorded in memory.
Secure data handling
Event log files and communication are protected with AES 128 bit encryption standard for security of the memory and the transmission of data files. Flash memory preserves the event log when the vehicle battery is disconnected.
Breath signature technology ensures that accepted breath samples come directly from a human subject and have not been filtered or altered before the alcohol sensor performs the analysis.
Events are recorded in memory with time, date and GPS coordinates to enhance compliance monitoring and to deter circumvention.
Wireless data transmission
Event log data is automatically transmitted from the ECU via GPRS cellular network to an ACS secure data center hosting AlcoTrack™ suite of applications for program management of client and vehicle data. Jurisdictional authorities may access the data online via a secure web based portal, and notifications may be sent by email/ SMS.
