Some alarm systems are tied to video surveillance systems so that current video of the intrusion area can be instantly displayed on a remote monitor, not to mention recorded. Some alarm systems use real-time audio and video monitoring technology to verify the legitimacy of an alarm.

Piping is an assembly of pipe, pipe fittings, valves, instruments and specialty components. Piping is divided into three major categories: Large bore pipe generally includes piping which is greater than two inches in diameter. Small bore pipe generally includes piping which is two inches and smaller in diameter. Tubing is supplied in sizes up to four inches in diameter but has a wall thickness less than that of either large bore or small bore piping and is typically joined by compression fittings. Within industry, piping is a system of pipes used to convey fluids (liquids and gases) from one location to another.
