2) Sensitivity
Sensitivity is defined as the response time to trigger the distraction alarm.
a) In Test Model
After entering into the test model, the sensitivity will be fixed as 1 second.
b) In Normal Model
RDT401B can make a comprehensive judgment and adjust the sleepiness
warning sensitivity automatically according to the vehicle speed, driving time period
and the driver’s driving behaviors etc., and the adjustment is made at an interval of [1s,
3s].
3) Driver Characteristics and Posture Self-calibration
After RDT401B is started and the vehicle speed exceeds 30km/h (which can be set),
the system will enter a period of 45-second self-calibration (the calibration time is 10s in
test mode). During this period, core parameters of the system will be calibrated
according to individual characteristics and driving posture of the driver. Please keep a
normal driving state in the process, please do not simulate fatigue and sleepiness.
Furthermore, the device will not issue a looking around warning before the calibration is
completed. After the calibration is completed, the device will send a reminder voice like
“beep~beep” and the system can normally trigger a posture warning.
4) Analog Image Output
RDT401B provides real-time analog image output in NTSC or PAL format. The signal
can be used to calibrate the orientation of installation, and can also be connected with
almost all the popular Car DVRs (Digital Video Record) on the market to store the
videos about the driver’s driving. The standard output can be adjusted through a DIP
switch 4#; the PAL system is default; and by dialing down, you can switch to the NTSC
system.
