When referring the business or commercial security, the term "security system" is the umbrella terminology for the following: intrusion, fire, access control and cctv. Each type of system brings different features to security. Sometimes a building may just have one system, like the required fire system. However, most businesses combine several systems together to create security layers.
Intrusion is what most people refer to when they use the broad term, "security." Intrusion systems include door and window contacts, motion detectors, outdoor beams, glass breakage devices, and panic buttons. When a contact or device is breached (someone opens the front door) then a signal is transferred to the monitoring station and the proper people are contacted.
Building codes state that U.L. fire systems are required in most businesses and are to be inspected and tested on a regular basis. Fire systems include smoke and heat detectors and can be tied into the building's sprinkler system. Pull stations are installed in designated areas to provide manual communication to the sirens or strobes and the monitoring station.
Access control is a term used to describe entry and exit points in a building and specifies who is allowed in certain areas. Access control can be thought of as "keyless entry" because systems utilize keyfobs or key cards instead of keys. Employee's "keys" can be removed or added easily through a computer program which ties into system.
CCTV is short for Closed Circuit T.V., or cameras. Cameras are placed strategically in or around your building and images can be recorded on a DVR or NVR or clips can be stored and transferred through the Internet to your phone or computer.
