I just want to add my feelings that this video shopping is creepy and underhanded. I dont care if buried somewhere there might be something about being spyed upon by third parties or whether it is technically legal in your state.
I am fine if the camera is in clear view, like with police cameras, but not hidden. I can see a phone device also when someone is pointing it at me and I understand that at someplace like a bank, police station or such there are cameras for security.
just my own 2 cents and all it is worth.
