What is Security?
Security is the degree of resistance to, or protection from, harm. It applies to any vulnerable and valuable asset, such as a person, dwelling, community, item, nation or organisation.
Home security is something applicable to all of us and involves the hardware in place on a property and personal security practices. The hardware would be the doors, locks, alarm systems, lighting, motion detectors and camera systems installed on your property.
Types of Security Systems
A system designed to detect intrusion or unauthorized entry into a building or area. Security alarms are used in residential, commercial, industrial and military properties for protection against burglary or property damage, as well as personal protection against intruders.
Access control may be enforced by personnel or with a device such as a turnstile. There may be fences to avoid circumventing this access control. An alternative of access control in the strict sense is a system of checking authorized presence, like a ticket controller.
