I want to install a home security system of four cameras and record them on a large hard drive. Due to some minor theft and aggravation. This is something I have little knowledge of. Two of the cameras will be covering inside of two out buildings, one the yard, the other front of house. I would like wireless system, motion activated, color, maybe be able to rotate and zoom cameras from my computer. If you can give me some direction or ideas I would very much appreciate it.
