Teswell MDVR with AI Solutions: TS-830X(Dual SD 4G 4CH 1080P/720P MDVR) and TS-610X/618X(HDD 4G 4CH/8CH 1080P/720P MDVR) can help fleet managers to monitor driver status on time. Regulate the driver's driving behavior to improve driving safety in order to minimize the risk of a road accident.


A: ADAS Advance Driving Assistance System

Minimizes the risk of suffering a road accident or colliding with other vehicles.

1:Lane Departure Warning(LDW): ADAS intelligent sensing will keep monitoring the current lane position of the vehicle in real time. If generating lane change, cross lane,and the turn signal is not activated in the process of driving,the system will trigger the lane departure alarm and voice warning.

2:Headway Monitoring Warning(HMW): Based on the configured speed (30KM/H),if the vehicle is ≤ safe distance from the vehicle in front,the system will trigger first level collision alarm and there will be voice warning.

3:Forward Collision Warning(FCW): Based on the configured speed (50KM/H),if the vehicle is ≤ safe distance from the vehicle in front,the system will trigger the secondary collision alarm and there will be voice warning

4:Pedestrian Collision Avoidance Warning(PCW):Pedestrian Collision Avoidance Warning,camera will scan and analyze the pedestrian,if the TTC(Time To Collision) is less than 2.7 seconds the PCW will be trigger and there will be voice alarm.


B: DSM Driver Status Monitor

An Anti-fatigue system for driving safety. Driver's driving status can be confirmed to reduce accidents

1:Fatigued Driving Alarm:DSM Intelligent Sensing Camera can detect abnormal physiological reactions of the driver,such as yawning,continuous squinting.The MDVR will remind drivers of driving safety through voice alarm automatically.

2:Answering Phone call Alarm:If the driver is detected answering a phone call during driving ,the DSM will see it as Answering Phone call Alarm,and there will be voice alarm.

3:Distracted Driving Alarm: The driver is not looking straight ahead(keeping turning head left and right,or head down).The threshold of not looking straight ahead will be left and right forty degrees,up and down forty degrees.There will be voice alarm if the alarm is triggered.

4: Abnormal Driver Alarm:The DSM will verify the driver's identity in the case of vehicle start-up, driving process, and timed capture.If the captured static image does not match the database, it will trigger the Abnormal Driver Alarm.And there will be voice alarm if the alarm is triggered.

5:Smoking Alarm:When the DSM detects the driver's smoking action,it will trigger the alarm,the cigarette in the mouth and in the hand will trigger this alarm.And there will be voice alarm.

6: Face Recognition

7:Function Failure Alarm(DSM/ADAS Blocked Alarm): The system will trigger an alarm when it detects that the camera is blocked.And there will be voice alarm.


C: BSD Blind Spot Detection

1:BSD blind spot detection category: pedestrians, non-motorized vehicles (bicycles, motorcycles, electric bicycles, tricycles, and other traffic participants that can be seen the contours of the human body), can be installed in front, sides and back.

BSD blind spot detection range:

When the vehicle is going straight

1)detection area: the right side of the vehicle lateral distance 10 meters,from the camera installation position forward longitudinal distance of 20 meters.

2)Warning area: the right side of the vehicle lateral distance 0.8m(configurable,not more than 10m),from the camera installation position forward longitudinal distance 15m

(Configurable, not more than 20m)


When the vehicle is turning right

1) detection area: the right side of the vehicle lateral distance 10 meters,from the camera installation position forward longitudinal distance of 20 meters.

2)Warning area: the right side of the vehicle lateral distance 4m(configurable,not more than 10m),from the camera installation position forward longitudinal distance 15m

(Configurable, not more than 20m)

The system can work at vehicle speed 0 to 60km/h,alarm range: 5 to 50km/h (configurable)

Illumination (>10 lux) can work normally, alarm accuracy >99% based on leakage rate <5%, static distance measurement error less than 5%.
