What is a primary use of on-board cameras in transportation?

On-board cameras in transportation play a crucial role in providing security and surveillance. Their primary use focuses on monitoring the environment surrounding the vehicle, which can include capturing footage of incidents, enhancing safety measures, and deterring criminal activities. This capability is especially important in public transportation, where ensuring the safety of passengers and staff is a priority. The presence of cameras can help in investigations following accidents or disturbances, providing valuable evidence that can contribute to improved safety protocols and overall system security.

While there are other functions that on-board cameras may serve, such as monitoring driver behavior or supporting passenger comfort, the primary objective remains focused on enhancing security and surveillance measures to protect both individuals and assets involved in transportation systems.
