Imagine a sudden collision on the road and the other party blames you for rear-ending the car in front of you. How would you handle that?
\nThe incident happened so quickly that you can't remember every detail, but you're absolutely certain you followed the law. The problem is you lack evidence to support your claim, while the other party insists on blaming you and demanding compensation.
\nThis complex dispute could be resolved quickly if your vehicle had been equipped with a dashcam from the start. Let's explore dashcams in detail and how this device protects your legal rights in traffic incidents.
\n\"The<\/p>\n

What is a dashcam?<\/h2>\n

A dashcam, often simply called a dashcam, is a specialized camera device mounted on the windshield or dashboard of a car. This device serves as a powerful supplementary security solution, recording all traffic events in front of, around, and inside the cabin throughout the journey and while parked.
\nVideo footage stored on the device serves as objective evidence to determine fault in traffic accidents or collisions. If your vehicle is damaged due to a third-party fault, this video data is crucial legal evidence for expediting insurance claim processing.
\nSo how does a dashcam work?
\nThe dashcam operates completely automatically; you don't need to manually activate the recording mode. The camera lens, pointed towards the front or rear windshield, will automatically start recording as soon as the ignition is turned on (ACC On), thanks to direct power from the vehicle's electrical system or battery.
\nVideo data is stored directly on a memory card (MicroSD card) or automatically synchronized to the cloud. Most current dashcams have a built-in loop recording feature, allowing the system to automatically overwrite the oldest video files when the memory card is full.
\nThe installation and commissioning process for a dashcam includes the following steps:<\/p>\n

    \n
  1. \n

    Install the camera in the optimal position on the front windshield to ensure the widest possible viewing angle.<\/p>\n<\/li>\n

  2. \n

    Make a safe connection to the vehicle's power supply system.<\/p>\n<\/li>\n

  3. \n

    When you turn the ignition key\/start the engine, the device will automatically activate upon receiving an electrical signal from the battery.<\/p>\n<\/li>\n

  4. \n

    Check and ensure that the high-speed memory card is correctly installed in the slot.<\/p>\n<\/li>\n

  5. \n

    Configure parameters according to administrative needs, for example, enabling ADAS warning features, collision sensors, or activating parking video recording.<\/p>\n<\/li>\n<\/ol>\n

    Classification of dashcams by outstanding features<\/h2>\n

    Dashcams on the market today incorporate many smart technologies, far surpassing basic recording devices. Below are some popular types of dashcams that businesses can choose from:<\/p>\n

    1. Single-channel dashcam<\/h3>\n

    Basic dashcams that only record the front of the vehicle are called single-channel devices. This configuration adequately meets the needs of individual car owners who only need to record all traffic events in front of the windshield throughout their journey.<\/p>\n

    2. Dual Channel Dashcam<\/h3>\n

    Often preferred for corporate fleets, this device records simultaneously in two directions: a panoramic view of the road ahead and a full view of the driver's cabin. Besides recording journeys, the device also supports comprehensive monitoring of the driver's demeanor and behavior while operating the vehicle.<\/p>\n

    3. Cloud or Wi-Fi connected dashcam<\/h3>\n

    This is a new generation of smart dashcams capable of transmitting data directly to a cloud server or quickly extracting it via internal Wi-Fi. This device represents a significant upgrade over traditional cameras that only store data offline on SD cards, thanks to the integration of a 4G data SIM to maintain continuous online connectivity.<\/p>\n

    4. Dashcam with integrated collision sensor (G-Sensor) and motion sensor<\/h3>\n

    Currently, most high-end dashcams are equipped with a G-sensor gravity sensor. When a sudden vibration or impact is detected, the system will immediately lock the video footage at that moment into an emergency event folder, preventing loop recording from overwriting and erasing evidence.<\/p>\n

    5. Dashcam with integrated GPS navigation<\/h3>\n

    New generation dashcams not only support cloud data extraction via Wi-Fi\/4G but also integrate a GPS positioning module. This feature allows for precise synchronization of the vehicle's actual location coordinates and speed in each video frame.<\/p>\n

    6. Dashcams that utilize artificial intelligence (AI)<\/h3>\n

    AI computer vision technology has been directly integrated into specialized camera systems, such as Cartrack's AI LiveVision solution. When detecting a frontal collision risk (FCW) or risky driving behaviors such as using a phone or falling asleep, the AI \u200b\u200balgorithm instantly identifies them and provides real-time audio warnings.<\/p>\n

    7. 360\u00b0 Camera System<\/h3>\n

    A 360\u00b0 camera system provides a panoramic view around the vehicle, from the front, sides, to the rear. This equipment is typically found on high-end vehicles, specialized vehicles, or high-value cargo vehicles requiring a high level of security surveillance.<\/p>\n

    8. Dedicated dashcam for corporate fleets.<\/h3>\n

    The dashcam series for commercial transport vehicles is directly and seamlessly integrated with the Fleet Management System. This platform allows operators to remotely monitor live footage (Live View) in real time on a computer or mobile application.<\/p>\n

    Guide to maintaining and extending the lifespan of your dashcam<\/h2>\n

    After understanding the operating mechanism and classification of the equipment, you need to focus on regular maintenance. Below are technical recommendations to help the equipment operate stably and reliably over time:<\/p>\n

    1. Regularly clean the lens surface<\/h3>\n

    The optical lens is the most important component of any camera device, including dashcams. Therefore, you need to periodically clean the dust and dirt from the lens surface to ensure optimal light gathering and consistently sharp, clear image quality.<\/p>\n

    2. Regularly check the power cords and camera mounting locations<\/h3>\n

    Loose connectors or unstable power supply are among the most common problems during operation. To ensure the camera always works continuously, make it a habit to check the power connector and the secure attachment of the camera mount every time you operate the vehicle.<\/p>\n

    3. Proactively replace the memory card when there are signs of malfunction<\/h3>\n

    MicroSD memory cards, after prolonged and continuous overwriting, can develop bad sectors, leading to recording interruptions or corrupted video files. If this happens frequently, you should proactively replace it with a dedicated memory card specifically designed for dashcams.<\/p>\n

    4. Regularly update your system software (Firmware)<\/h3>\n

    Regularly updating to the latest firmware from the manufacturer ensures smoother device operation. This helps patch system vulnerabilities, prevent crashes, video saving issues, and unexpected software conflicts.<\/p>\n

    5. Avoid parking in excessively hot weather<\/h3>\n

    When your vehicle is equipped with a dashcam, avoid parking it directly in direct sunlight for extended periods. Excessive heat buildup in the cabin can reduce the lifespan of electronic components, cause recording file errors, or trigger the device's automatic power-off protection mechanism.<\/p>\n

    Legal regulations regarding the use of dashcams in Vietnam<\/h2>\n

    In the Vietnamese market, the installation and extraction of data from dashcams\/surveillance cameras on commercial transport vehicles are strictly regulated by the current legal framework. Businesses need to pay particular attention to the following regulations:<\/p>\n

    1. Decree 13\/2023\/ND-CP on Personal Data Protection and Decree 319\/2026\/ND-CP<\/h3>\n

    Image data, driver and passenger faces, or personal identification information recorded by cameras are strictly protected in accordance with Decree 13\/2023\/ND-CP and Clause 4, Article 6 of Decree 319\/2026\/ND-CP.<\/span>Unauthorized copying, distribution, or public posting of these videos on social media without the data owner's consent is a violation of privacy laws and will be severely punished.<\/span>.<\/span><\/p>\n

    2. Law on Electronic Transactions No. 20\/2023\/QH15<\/h3>\n

    Image and video data extracted from dashcams are recognized as data messages and have legal value as evidence before authorities or in court. Therefore, you can absolutely use recorded video footage as authentic evidence to protect your legal rights in traffic accidents, disputes, or to assist in criminal investigations on the road.<\/p>\n

    3. Law on Road Traffic Order and Safety No. 36\/2024\/QH15, Decree 319\/2026\/ND-CP, Circular 71\/2024\/TT-BCA and National Technical Regulation QCVN 06:2024\/BCA<\/h3>\n

    According to Law No. 36\/2024\/QH15 and Decree 319\/2026\/ND-CP, the installation of vehicle tracking devices and devices for recording images of the driver\/passenger compartment is mandatory for commercial transport vehicles.<\/span>All hardware, recording mechanisms, and data transmission streams to the Traffic Police Department (Ministry of Public Security) must strictly comply with the National Technical Standard QCVN 06:2024\/BCA and Circular No. 71\/2024\/TT-BCA.<\/span>At the same time, the installation of cameras on motor vehicles must ensure technical safety requirements: it must not illegally interfere with the original electrical system, must not deform the safety structure, and must absolutely not obstruct the driver's view while operating the vehicle.<\/span><\/p>\n

    Based on the legal framework above, please ensure that you only use video data from your dashcam for internal management, legitimate business operations, and traffic safety verification purposes, so as not to infringe on the privacy of others.<\/span>You can also proactively use this data as transparent electronic evidence in case of an incident on the road.<\/span>.<\/span><\/p>\n

    What are the regulations regarding dashcams in different countries around the world?<\/h2>\n

    In some markets, such as South Korea, dashcams are almost a mandatory standard feature on new vehicles. However, in most countries, their installation is encouraged but must comply with strict regulations regarding personal data protection.
    \nThe unauthorized distribution or misuse of dashcam footage can result in severe administrative penalties or criminal prosecution in many countries. Therefore, recorded data should only be used for internal management purposes, insurance reconciliation, or provided to authorities when resolving legal violations.
