he onboard surveillance system is necessary to provide information to authorities in case of a security incident. The cameras being used in the project have to meet several requirements for durability — primarily the ability to withstand damage by hostile parties — so the casing must be certified as impact resistant. In addition to external factors, the devices also need to comply with traffic regulations, as they are being used in a vehicle, as well as product safety rules.A bus is a high-frequency vibration platform, but the project’s objectives require clear images. As such, the cameras selected have specifications that are generally superior to those of normal cameras to ensure a clear picture.Normal security cameras usually incorporate infrared lights to improve low-light visibility. These lights are typically accompanied by a red light, which is a telltale to let people know that surveillance is underway. However, for the Bogota project, the red light was eschewed, because the primary objective is to help protect passengers without making them feel like they are being watched, Ku said.
