Blind spot monitoring (BSM) systems have become integral safety features in modern vehicles, offering drivers enhanced awareness of their surroundings and minimizing the risk of accidents caused by unseen vehicles. While they share the same goal, they employ different technologies, each with its own set of features and benefits.

Camera-based BSM systems utilise cameras installed on the side mirrors or rear of the vehicle to detect nearby objects. They offer high-resolution imagery, providing detailed information about the surrounding environment. This enables accurate detection of vehicles, pedestrians, or obstacles in the blind spot area. Camera-based systems excel in identifying stationary objects and offer superior image clarity, especially in adverse weather conditions such as rain or fog.

On the other hand, radar-based BSM systems use radio waves to detect objects in the vehicle's vicinity. Radar sensors emit signals and measure their reflection to determine the presence and distance of nearby objects. Radar-based systems are effective in detecting moving objects and have a longer detection range compared to camera-based systems. Unlike camera-based systems, radar sensors are less susceptible to environmental factors like glare or low light conditions, ensuring consistent performance in various driving scenarios.

In summary, camera-based BSM systems provide detailed visual information and excel in detecting stationary objects, while radar-based systems offer longer detection ranges and perform reliably in diverse weather conditions. Ultimately, the choice between the two depends on factors such as driving environment, personal preferences, and the specific needs of the driver.
