The usual home user systems like Logitech and others? That is, you find these on amazon but your comments make me think you want a consumer system or what you buy from the usual place.
Due to some thefts of packages from my front porch, I need a stand alone home system with four cameras and a seperate recorder. It doesn't need to be real cheap but I don't want to take out a home equity loan for it either! I know everyone has an oppinion but I want a reliable system. Wireless preferred.
