I. What is an ADAS dash cam?
An ADAS dashcam is a type of car dashcam equipped with an ADAS system. Its main function is to remind the driver to stay within their lane. If the driver deviates from their lane, it will issue a voice warning. It will also warn the driver if they are too close to the vehicle in front, thus improving driving safety.
II. Are ADAS dashcams the same as regular dashcams?
No.
Regular dashcams primarily record data and prevent staged accidents. ADAS dashcams, in addition to these functions, also reduce the risk of collision through warnings, prioritizing safety.
Furthermore, while ADAS dashcams and regular dashcams may look similar in terms of hardware, the cameras differ significantly: For clearer recording, dashcams use ultra-wide-angle lenses with higher resolution, requiring only a 30-meter detection distance; however, to allow the chip sufficient time to make judgments and reactions, ADAS dashcams for hazard warnings require a longer focal length, with a detection distance of at least 70 meters.
III. Is an ADAS dashcam practical?
An ADAS dashcam is a car dashcam with ADAS functionality. Compared to a dedicated ADAS system, it’s definitely not as useful. For novice drivers who can’t accurately judge the distance to the car in front and might drift out of their lane, an ADAS dashcam can help. However, for experienced drivers, it’s not as practical.
Furthermore, ADAS dashcams aren’t as reliable as many people imagine. Since they’re not a dedicated ADAS system, their functions are generally software-based, resulting in lower accuracy. If needed, it’s better to install a separate ADAS system or buy a car with a built-in ADAS system.
IV. What is an ADAS System?
ADAS utilizes various sensors installed in the car to collect environmental data inside and outside the vehicle in real time. It processes this data through static and dynamic object identification, detection, and tracking, allowing the driver to detect potential hazards as quickly as possible and avoid accidents such as rear-end collisions. This includes systems like LDWS (Lane Departure Warning System) and FCWS (Forward Collision Warning System). Autonomous driving represents the ultimate form of automotive intelligence, and ADAS (Advanced Driver Assistance Systems) is an essential step towards achieving this goal.
It can remind drivers whether they are staying within their lane, provide voice alerts if they veer off course, and warn them if they are too close to the vehicle in front. This prevents drivers from veering off course, avoiding rear-end collisions, and significantly improving driving safety.
