6. Installation & Calibration
The driver fatigue monitoring system should be place in the position that within angle to the front
view of the driver range about +/- 10 degrees and distance to the driver is about 0.8～1.2 meter.As
the following figure shows, to choose a proper position for fixing the device on the dashboard,
installation and calibrationshould be operated synchronously.So an assistant is recommended to
finish the calibration and registering (details operation on chapter 6, 7), who is to adjust the device,
guide the driver, and configure the device setting, etc.
Figure 7
1. Building the Wi-Fi connection
Before calibrating the driver fatigue monitoring system or setting the parameters of the device,
make sure the device is powered on. Then refer to following steps to finish the Wi-Fi connection
between mobile phone and driver fatigue monitoring system:
1) Install the APP, all of the operations and the parameters setting can only be done according to
the APP.
Note: the App is only available in Android version yet, and it can download in Google play, named
“DSMA”. The IOS version is coming soon.
2) Search the driver fatigue monitoring system Wi-Fi hot spot named “DDWS-xxxxxxxx” according
to the mobile phone, and connect this Wi-Fi hot spot with the default password “12345678”.
Refer to the below figures.

4) Run the specified APP “DSMA”, it will enter the main menu as follows, and touch the “Wi-Fi”
Button to establish the communicationrelationship between the phone and driver fatigue
monitoring system. And the effective communicationdistance of Wi-Fi is about 7m, please keep
in this range.
Figure 10
After finishing Wi-Fi connection, we can calibrate the driver fatigue monitoring system or operate
some other settings about the device according to the APP.
2. Operations of installing and calibrating
1) After making sure the driver’s driving posture and view straight as in normal driving, the assistant
can touch the “Calibration”button in the main menu to enter a real-time mode, as the below
figure.
Figure 11

12
There will be a color square in the middle of the screen, the square is with three color modes:
a) Green, it means the relative angle and distance between the driver and driver fatigue
monitoring system is appropriate.
b) Red, it means the device is too closer to the driver or the angle of the device is not suitable.
The assistant should try to adjust the relative distance or angle of device, make sure that the
driver’s face is fully presented in the middle of the screen, being inside the color square. After
finishing above steps, the color of the square may turn green.
By the way, the assistant can adjust the pitch angle when the fixing hex nut is loose, as the
below figure. After adjusting to appropriate angle of the device, tighten the fixing hex nut.
Fixing hex nut
Figure 12
c) Yellow, it means the relative distance and the pitch angle of the device is appropriate, but the
included angle between the device and the front view of the driver is greater than +/- 10 degrees,
the assistant should rotate the device on the dashboard slightly until the square turn and stay
green.
2) After making sure the color square stay green, the assistant should press the "start" button and
follow the voice to guide to begin calibrating, the driver must keep the view straight as in normal
driving during the calibrating process which lasts about 10S. After calibrating, the device will
feedback by voice:
a)"Calibration is successful" indicates a successful calibrating. Then the APP will exit the
real-time mode automatically.
b)"To left" or "To right" indicates calibration is unsuccessful because the driver’s head is inclined
left or right. Slightly adjust the device angle again, and then repeat the calibrating process.
By touching the "cancel" button, you can exit the calibrating process at any time.
3) After finishing calibrating, the assistant should mark the current device position on the dashboard
by pencil carefully, then fixing the device on the marking position by 3M glue. According to above
steps, the calibration and installation is done.

7. DMM and FRS functions
After the device power up or reboot, the FRS function will first run automatically. Then, the device
will enter and keep in DMM mode. To make sure these two functions preform properly, please install
and calibrate the driver fatigue monitoring system carefully according to the guide of Charter 6
“Installation & Calibration”.
7.1 Driver Monitoring Module (DMM)
The DMM function includes five sub functions: Fatigued Driving Warming, Distracted Driving
Warming, Driver Calling Warning, Driver Smoking Warning, No Driver Warning. DMM just runs when
the speed is above the starting speed set by the APP, please refer to chapter 8.4 for the operation
guidance.
When a warning is triggered, the device will send out a voice to alarm the driver, record the video of
this warning event, and the warming information can transfer to other devices by CAN or
UART(232).
After the DMM function is running normally, there will be some elements overlaying in the real-time
video of the monitor, just as the below figure, these elements can be turn on or turn off by the APP,
please refer to the chapter 8.4.

1. Fatigued Driving Warning
Fatigueddriving detection is based on PERCLOS (the percentageof eyelid closure over the pupil,
over time). The device triggers a fatigued driving warning, when the driver’s eyes close more than
4 seconds or the eyelids droop over time.

14
Figure 21
2. Distracted Driving Warning
Distracted driving warning is triggered when the device detects that the driver turns his (her) head
to one side (left or right) more than about 30 degrees for a long time (about 5 seconds).
Figure 22
3. Driver Calling Warning
Driver calling warning is triggered when the device detects that the driver holds the mobile phone
for a time more than about 3 seconds.
Figure 23

15
4. Driver smoking Warning
Driver smoking warning is triggered when the device detects that the driver keep smoking for a
time more than about 3 seconds.
Figure 24
5. No driver warning
No driver warning is triggered when the device cannot detect a driver for a long time (about 7
seconds).

7.2 Face Recognition System (FRS) With Imobilzer Function.
Face Recognition function detects whether a driver is registered (or qualified to drive the car) and
feedback the recognition result by voice. If the unregistered driver is detected, the video of
recognition process is recorded. Thus, before performing FRS, please register the drivers at first.
Once Face recognize match and got success, it can be configured for immobilizer to triger an output
to activate a relay immobilizer.
1. Register new drivers
a).Touch the “Face Recognition” button to enter the face recognition management menu.
“Face login” item is to turn on (or off) the FRS function after the device powers up or reboots.
Figure 13
b). Touch “Newface” to registera new qualifieddriver, and the drivers should be without the glasses
during registering their facial information. After entering the driver’s name (or ID, etc.) and
confirming, it comes to a live video screen with an assisting square. Make sure that the driver’s face
is fully in this square. For better face recognition, it’s strongly recommendedthat the driver shakes
his head slightly during this registering process.
The assisting square will show different colors to hint the registering state:
Green indicates that the system is recording the face information rightly.
Yellow indicates that the system can’t detect the driver’s facial characteristic.A face
outside the square often leads to this problem. Make sure that the device is properly installed
and calibrated. It rarely happens after proper calibration.Adjusting the device and guiding the
driver to make his face fully in the square will also do the trick.
White indicates that the system detects a static face.A slight head shaking often solved
this problem.The slight movement of the face is required to prohibit a fake identity by the
picture.
Note: if the system can’t detect a face rightly overtime, it will exit to the face recognition
managementmenu and gives a failure notice.

17
Figure 14
c) After recording the new face rightly, the system will pop up a notice to select whether to register
another new driver (“new face”) or to finish the registration.
It may take some time from a few second to 2 minutes to finish the registration, according to the total
number of registering and preregistered drivers.
Figure 15

18
Note: If the device powers down or restart due to some external factors during the registration
process, all the registering drivers' face information is already saved. The system will prompt
a message when the APP is reconnected. To choose the “CANCEL” button to abandon the
last registration, or to choose the “REGISTRATION”button to finish last registration.
Figure 16
2. Manage the drivers' information
To manage a registered driver's information, press the driver's name (or ID, etc.) in the menu to
enter the management interface and perform deleting or renaming.
Figure 17

19
Long pressing of a name will come to the batch mode, and then batch deletion is available.
Figure 18
3. Driver Recognition
There two ways to run the FRS, firstly, press the “TEST LOGIN” option in FRS setting page, refer to
the above figure. Secondly, after the system powers up or reboot, the FRS function will
automatically run. It will guide the driver to shake his (her) head and blink for recognition process by
voice. The recognition results are feedback both by voice and notice in the video of monitor as
follows. Once Face recognize match and got success, it can be configured for immobilizer to triger
an output to activate a relay immobilizer.
When an unregistered driver is detected, the system will record the recognition process video into
the micro Micro SD card for playback. About how to play back the video, please refer to chapter 8.3.
Note: The start-up of the driver fatigue monitoring system may take about 10S, please keep a
normal driving posture for better face recognition after hearing the voice guide.
