Camera-based Driver Monitoring System

Camera-based Driver Monitoring Systems

In the field of fleet and road safety, DMS (Driver Monitoring System) and DSM (Driver Status Monitoring) are core technologies that can monitor driving behavior, prevent accidents, and optimize fleet management.

Concepts of Driver Monitoring System

1. DMS

Short for Driver Monitoring System, it continuously monitors driver attention and alertness, standardizes driving behavior, prevents accidents, improves management efficiency, and also covers alcohol detection and identity verification.

2. DSM

Short for Driver Status Monitoring (also known as Driver Safety and Monitoring Solutions), it focuses on monitoring the driver's status and safety-related behaviors during driving.

3. Differences Between the Two

①　DMS emphasizes the overall system with a wider coverage scope; DSM focuses on the real-time status of the driver.

②　The two terms can be used interchangeably in some scenarios, and the application scope of DMS is continuously expanding.

Importance of DMS

Data shows: Distracted driving caused more than 3,200 deaths in 2023; 71% of drivers aged 18-29 engaged in fatigued driving; fatigued driving leads to more than 6,400 road deaths annually, resulting in social losses of 109 billion US dollars.

Values of DMS:

1. Early identification of distracted/fatigued driving to prevent accidents, protect lives and reduce costs.

2. Reduce risks to vulnerable road users and comply with the EU DDAW/ADDW mandatory requirements.

3. Provide video materials to support driver training and the cultivation of safe driving habits.

Working Principle of Driver Monitoring System

It integrates cameras, sensors and AI algorithms to monitor driver attention in real time. The core monitoring items include: eye/head movements, fatigue/distraction, mobile phone use/smoking, seat belt wearing/seated status.

When unsafe behaviors are detected, voice/visual alarms are issued immediately to help drivers concentrate and avoid collisions.

Privacy and Security

Privacy leakage is related to technical solutions and management models:

①　Edge computing: Data is processed locally with no privacy risks; cloud computing: Data is transmitted to the cloud with potential leakage risks.

Independently deployed servers with strict authorization can reduce risks; open hosting without authorized management increases the probability of leakage.

Fleet Safety Risk Management

DMS is a core tool for logistics fleet risk management. Data is uploaded to the management platform to facilitate:

①　Identification of unsafe driving trends

②　Personalized driver guidance

③　Reduction of insurance claims and liability risks

④　Improvement of the overall safety performance of the fleet
