I. Product Synopsis
Roadefend RDT401P is a bran-new Driver ADAS Safety Monitor System based on the fifth
generation of video based driver state analysis technology, which gives a warning of fatigue drive
and kinds of dangerous driving behaviors by means of image recognition and driver’s mental state
analysis to decrease accidents caused by fatigue drive. Furthermore, RDT-401P-WH is also
capable of sending abnormal data and videos via 4G network to an end-user platform management
center to avoid occurrence of accidents by immediately taking effective measures.
The product performance meets the relevant national standards of "GB/T 19056-2012", "JT/T794-
2011" and "GB/T 26773-2011".
1. Value of Fatigue Warning
Fatigue has long been an inevitable problem that is controlled to an extent for drivers, for example,
when driving two hours at a speed of 100km/h, the driver has to struggle to stay awake on account
of his lower levels physiological functions followed by inattention. In general, accident rates are
extremely high when the driver drives more than 6 hours a day or is lack of proper rest, for example,
only having a rest of less than four or five hours last night. In addition, with the popularity of smart
phones, more and more drivers are used to playing his cellphone while driving, it also will cause a
popularity of accidents.
A set of terrible statistics has already been reported, indicating that 72% of all accidents occur due
to drivers themselves and 25~30% thereof are caused by fatigue drive; that 40% of all serious and
fatal accidents are fatigue related; that 70% of all drivers will fall asleep at the wheel on the highway
and specially happens to those who likes playing their cellphones while driving.
Therefore, it is a great value to eliminate fatigue at driving for sake of the drivers, families,
companies, as well as the society.

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
RDT401P 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 RDT401P 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

Instructions for use of RDT401P 2018-RDT401P-R001

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
RDT401P 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.
5) Video Storage
RDT401P can store the driver’s real-time driving behaviors into a high-speed TF (higher
than Class 10) card by 3 minutes as a unit and the default is standard definition; for
example, a 8G card can store videos for about 3 days’ driving behaviors; its resolution can
be configured as high definition storage (720P); and the SD card can support up to 256G.
6) 4G communications
RDT401P can transmit alarm information, alarm videos and other related data to the
fatigue monitoring management platform via 4G communications for easy supervision
and management.
7) Input/Output Interface
RDT401P supports one-way PWM speed signal inputs Meanwhile, it also support one-
way switching signal outputs, which can control some accessory devices like the vibration
cushion or refreshing smell generator to trigger relevant actions when the sleepiness
warning happens.
8) Communication Interface
a) RS232/485
RDT-401P-WH supports one-way RS232 or one-way RS485, realizes the data
communication with the video terminal by RS232 or RS485 interface.
b) CAN
RDT401P supports one-way CAN communication, supports sending alarm messages to
the CAN bus, and supports obtaining vehicle information from the CAN bus, such as time,
speed and braking etc.
c) Ethernet Port

Instructions for use of RDT401P 2018-RDT401P-R001
6
RDT401P supports 100M Ethernet communication and realizes data communication with
RDT402P or video terminals, supporting remote updating of devices and video
transmission.
9) Alarm Events Recording
RDT401P can make a record for each alarm information, including the position, event,
alarm type and the relevant file name of alarm video, etc.
10) Local Storage of Alarm Images
RDT401P will create folders with year.month.day in an SD card and store the alarm
images of the day sorted according to types of fatigue warming (sleepiness, calling,
smoking, etc.).
11) System Upgrade
The device is started by placing the upgrade package file in the TF card; and once you
hear a voice like “beep, beep, beep” and the device is restarted, it means the device
upgrade operation has been done.

VI. Friendly Reminder
1. Will you drive when you are in fatigue?
Fatigue driving is different from drunk driving, and people always choose to or have to drive even
though they feel tired because they claim they are alert to fatigue or they are in a hurry sometimes.
Therefore, there is inevitably the following problems:
The first problem: people will still choose to drive even though they are tired because they have
to do so;
The second problem: the drivers think that they can control the fatigue. When having a sense of
fatigue, a driver may argue that he can eliminate it through conventional methods such as, having a
cup of coffee and other refreshing drinks, smoking, turning music volume up, opening windows,
scratching his head, twisting his neck.
However, we should accept the fact that fatigue cannot be eliminated by means of relying on
subjective thoughts of the driver with the aid of applying the above-mentioned methods to avoid
falling asleep. Those irritating behaviors, such as smoking, increasing the volume of the radio,
drinking coffee, opening windows cannot actually prevent “drowsiness–induced substance" from

Instructions for use of RDT401P 2018-RDT401P-R001
12
influencing the brain, and conversely, they cause paralysis to the driver.
Do you know? Drinking excessive coffee can cause insomnia, headaches, allergies and anxiety.
Do you know? It takes more than 10 minutes for caffeine to get into your blood system to finally
generate a stimulus, so a cup of coffee would not have such a quick play as required but you have
already fallen asleep. Also, if you have become accustomed to effects of caffeine, stimulating
effects will be weaker.
Do you know? Opening the window and increasing the volume of the radio can indeed increase
your alertness in a short time, but it will not last long.
2. RDT401P Benefits
RDT401P employs the method of combining the image recognition with the driving behavior
analysis to give a well-intentioned warning when you are tired and inattentive. Once serious
fatigue occurs, the system will give you a wake-up call in time, which is a critical moment between
life and death.
What a critical moment between life and death, seizing this moment, the wife can give her rushing
husband a reminder;
What a critical moment between life and death,
seizing this moment, the driver will not worry about his safety;
What a critical moment between life and death,
seizing this moment, the passenger will not worry about his safety.
Hindsight is not our aim, what is important is to reduce tragedy.
VII. Security Warning
Before using the product, please be sure to carefully read the following precautions to ensure safety.
Warning 1: In order to put the fatigue warning system to be in good account, users of this product
are responsible for the proper installation and the safe utilization of the system so as to ensure this
product will not interfere with the normal operation of the vehicle and other vehicle safety devices,

VIII. User Notice
The product is powered on; and after the vehicle travel speed reaches the speed value (default
15Km/h) for triggering the fatigue warning function, the product will enter the normal working
condition.
The product can effectively reduce the probability of accidents caused by driver fatigue, but
cannot eliminate the symptoms of driver fatigue, so the driver needs to consciously have a rest
in order to completely eliminate fatigue symptoms.
The user needs to cooperate and know that our product needs to access the signal, such as
power supply, GPS antenna, and 4G antenna.
