Peephole cameras are legal in most states because they do not invade the privacy of the person being recorded. The camera is only recording what is happening in public view, so there is no expectation of privacy. However, there are a few states that have laws against recording audio without the consent of the person being recorded. So, if you live in one of these states, you may want to check the law before using a peephole camera.
Peephole cameras can be a great way to improve security at your home or business. They can deter criminals and help you identify visitors. If you do choose to use a peephole camera, be sure to follow the law and respect the privacy of others.
