Legal Question in Criminal Law in California

Whether or not you have cameras on your property is completely irrelevant to whether you would be found liable in a court of law with respect to third parties injured on your property. This is also not a criminal law question. This category involves questions over the law governing the criminal justice system, and people charged with crimes.

I agree with Mr. Roach. You seem to be asking whether the victim of a crime who believed he was on camera could successfully sue the property owner who posted the signs. Unless there is a lot more to the story, the answer is no. The lack of cameras would not have caused the crime, and the owner owes no duty to people on his property to make video recordings. Only the criminal would be liable.
