You watch your outdoor cameras late at night, all day long you keep the wireless monitors on hand, you even tug them to work. They have a nice night vision feature that keeps you up late just watching your yards, toggling between four cameras. You have them set up to turn the monitors on if something breaks the infrared beams that criss cross the yard One night the monitor light awakens you. There is someone in your back yard, someone holding a hammer and a hand gun.
