Hello and welcome to JustAnswer. Please note: This is general information for educational purposes only and is not legal advice. No specific course of action is proposed herein, and no attorney-client relationship or privilege is formed by speaking to an expert on this site. By continuing, you confirm that you understand and agree to these terms. I am sorry to hear about this situation. Visual recording is not illegal provided that: 1) The recording device is on your neighbor's property, and2) The camera is trained on something where you do not have a reasonable expectation of privacy. Ergo, if the camera is pointed at your home, garage door, patio, and back yard - this in itself is not illegal. However, pointing cameras at windows may be actionable. Not criminally however - civilly. To sue in a state court, one needs to have a "cause of action." There are numerous causes of action, such as "breach of contract
," "negligence," "fraud," "unjust enrichment," etc., as well as causes of action rooted in statutory law. Every state has their own although they are very similar to each other in every state because they all stem from the same common law. A pleading in Court needs at least one cause of action, although it is not unusual to have more than one. Here, having the cameras trained on windows may be considered an invasion of privacy - intrusion of solitude. Intruding upon another's solitude or private affairs, physically or otherwise, is subject to liability if this intrusion would be considered highly offensive to a reasonable person. However this would be up to the Jury to decide. Before simply filing suit, one may wish to send a cease and desist letter threatening a lawsuit unless they dismantle said cameras. Perhaps the threat itself would be enough to have them stop. I hope this helps and clarifies. Please use the SEND or REPLY button to keep chatting, or please RATE when finished.
