Prompted by tonight’s Family Guy. Are they legal in department stores? Boutiques? Illegal but stores put 'em in anyway? Doing a search, it seems they might be legal (in America, at least, I don’t know about Canada) as long as there’s no audio. Well, what’s the straight dope?
Some states do allow video surveillance of employee-only changing rooms and the like, provided that employees are notified that surveillance is taking place.
Everyplace I’ve seen 'em, I’ve also seen a notice posted outside the dressing rooms, notifying customers of them.
I don’t know if this is required by law, but it probably could be used in court: ‘notice was provided beforehand, so the customer could decline to use the changing room if they objected’.
I doubt that most states have any laws specifically for this situation. So a customer would have to try to get the store security staff charged under the general ‘peeping tom’ laws. In most states, such laws have language like ‘peeping for the purpose f sexual gratification’. I’d think it would be hard to convince a local D.A. to charge the securit staff at a store under this.
