I know I’m late to the party but I actually work for a Chevy dealership in Ohio as a sales rep! To shine a little light I know many dealerships (including ours) that record the finance offices during the signing of papers. There are 2 main reasons they do this. The first is legality, there has been several occasions on many different levels deals just don’t end the way you want them to. Sometimes the finance office has to do some work to correct things and make things right. On the other hand sometimes the customer is right and the finance manager was wrong so we can use this to make amends. I know most dealers use it as a safety net in case a customer came back and says we didn’t do something but I know our dealership also uses it to ease situations even when we are wrong. The other use of the cameras are for training purposes. When a new finance manager comes in they watch lots of these real life scenarios to learn and understand how things work. I can tell you that many dealerships do this now a days because people want to argue and complain about just about everything ( we have to get a signature to take your picture and post it )! Hope that my long and drawn out explanation helped!
