One of the main purposes of in-vehicle cameras in public transportation vehicles is to provide security and deterrence against negative situations. These cameras are not monitored continuously. If deemed necessary for security, only the camera records related to that incident are accessed and detections are made.
In addition, in-vehicle cameras are also activated in case of any lost items.
When any passenger loses an item, he/she can make a request by informing the public transportation line and time he/she uses via phone or internet. When such a request is received, images from the camera system are accessed and passengers can be informed about the lost item.
