If your business operates in an all-party consent state (which means it's illegal to record conversations unless everyone involved knows about it and gives their permission), there are a couple of things you can do to make sure you don't record anything illegally: Place a warning sticker in every vehicle, which states that audio-recording dash cams are in use Have your drivers inform everyone they drive with that they're using a dash cam that can record audio, and ask if that's okay. If their passenger says no, have them turn the audio recording function off Disable the audio recording function on all your dash cams, and just never use it (this is probably the best option – after all, you don't need audio recordings to see what's happened on the road)
