Security surveillance may be CCTV (Closed Circuit Television) systems, cameras, and recording devices that function either in analog or digital.
Access Control involves using technology to control persons and vehicles moving onto, around, and off from a site or business. These systems can be “simple” or “smart” allowing basic access permission through to Human Resource functions such as limited access and movement management.
Business security alarms come in many forms, but essentially they use a sensor to detect movement or someone gaining entry by force to a certain area. If set off, the alarm sends a signal to an alarm panel which then creates an action dependent upon its programming. This action is most often an automated phone signal to a computer but can be to a phone line.
The resulting action is an investigation, often the contacting of key personnel or the dispatch of a mobile patrol security guard which is the “response” to the alarm activation.
