Amazon has an AMAZING one that isn’t all the expensive. We have it for other reasons and don’t need it anymore. But we were able to view it on our tv and on our phone. We also were able to save video clips. We also were able to buy extra storage. We didn’t really need the extra storage but we were sure how long the problem would go on for. So we needed all of it for documenting.Get as much video of her harassing you and make sure to show that you are well within the local ordinance. Take evidence to local police office and file a complaint and request a restraining order or a no trespass order. If you can afford if get a good surveillance camera and recorder.
This is the link for it. I absolutely LOVE this system.
