Security is used to protect people, property, goods and services. Protection from loss, damage, injury or death is the objective of having security in place. It can operate in many forms and circumstances and aims to provide peace of mind and protection.
Household security comes in the form of systems used to protect property from damage or theft. Items under this umbrella are burglar alarms, deadlocks, CCTV, security lights and sometimes guard dogs to scare off potential intruders.
Car theft is common and there are many security measures that can be taken to protect vehicles. Alarms, immobilizers and steering wheel locks are often used to deter thieves from gaining access to parked motor vehicles.
Larger scale security to protect business premises uses the aforementioned items such as alarms, CCTV and security lights. More commonly large organisations use security guards to protect their premises during the night or when the premises are unoccupied.
Public places such as airports, museums and shops where a large number of people are passing through, have extensive security in place to protect the public and avoid incidents of theft or damage. Airports operate bag searches and use x-ray machines to view passengers’ personal possessions and clothing.
Museums and shops often use CCTV to monitor potential occurrences of theft or damage. Museums also operate bag searches to protect their visitors from potential terrorist activity or theft.
