I am thinking about installing some security cameras in my business. Not at all looking for crime-prevention, since they're small enough to hide in the shadows, but rather a means to record if something does happen and hopefully give a photo of the criminal. I also see it as a major deterrent to any extortions/problems from officials. I'm concerned if there are any laws governing placement, who/what/when can be recorded, if a notice must be posted, etc. Also, assuming something happens and is recorded, would the video be able to be used against someone or would it not be accepted by the police? I haven't seen many businesses with cameras, so I haven't been able to find any good examples or even anyone to ask.
