Who can get the video of the bus if something is lost during the trip?

The bus company where the bus is located is looking for a driver, otherwise a sign will be posted on the bus and there will be a phone. But in this case, if you lose something during the trip, you generally don't care, and you will take 80% or full responsibility. But if you find something very important, you can call or find the investigation video of the unit to which the bus belongs, but I personally think you are unlucky because there are too many people. Even if you find that person in the car, where will you find it? I just don't know if your bus ticket is registered with your ID card. If there is, you can find the right person. If you just buy a ticket casually, you can only remember it next time, but my purpose is definitely to hope that you can get it back.
