Hi. My grandma has been hearing people around her property and we’d like to install some security cameras. However, she doesn’t have an internet connection. I know I could do wired cameras, but that seems like a huge undertaking. Are there any wireless camera options that don’t require internet that are reliable? It would also be nice if the cameras could be hooked up to a hardrive and a live monitor. Thanks all, I’m pretty good with DIY and AV, but don’t know a ton about security systems.
