DashCam Rules in 50 US States and Consent Rules

For those of you who are looking for the definition of consent: (From the same article)

"What constitutes “consent” is also an issue of contention when you are considering recording a conversation. In some states, “consent” is given if the parties to the call are clearly notified that the conversation will be recorded, and they engage in the conversation anyway. Their consent is implied. For example, we have all experienced calling a customer service department only to hear a recorded voice warning, “This call may be recorded for quality assurance or training purposes.” It is usually a good practice for practitioners to let the witness know they are recording the conversation to accurately recall and commemorate the testimony being given – such as during the taking of a witness’ statement."

Ummm...thank you. I was excited to open it at first, but then for everything it basically says I need consent from all parties.

So naturally, I have to know what constitutes a "consent." It actually makes me wonder 

Here's what it says for me: "The recording, interception, use or disclosure of any conversation, whether in person or via wire or telephone, without the consent of all the parties is prohibited. However, telephone equipment, which is furnished to a phone company subscriber and used in the ordinary course of business, as well as office intercommunication systems used in the ordinary course of business, is excluded from the definition of unlawful interception devices."
