The word security comes from the Latin words securus and securitas which means safe and freedom from danger or care. Security has always been an important factor for us. It has to do with the resources we have. Even animals need security, for example a sparrow will protect its nest from predators, Squirrels store and hide their food, lioness protect their young and many other animals use different methods to protect what’s important for them.
In historic times with the development of early communities and the accumulation of wealth and resources made towns and countries susceptible to attack and their wealth and resources stolen. This led to creation of walled cities and many other physical barriers for protection. This was not enough as walls could be broken and climbed and there were people within the city who would attempt to steal so people came up with hiding places, safes, vaults, locks and traps. These were the main protection method at the time and they were quite successful to a degree but not perfect unlike today where CCTV installation Gold Coast and cameras are everywhere.
More people were aware of these security measures and given time anything can be cracked, picked and stolen. As an example given time safes and vaults could be broken and the contents stolen, hiding places are not useful when the house is burnt down or destroyed, locks can be picked and traps became dangerous for the owners as it was always a hazardous risk.
Animals especially dogs played a large and useful role in security. Many people began to use guard dogs for protection and the dog alerted the people when there were intruders. Even today dogs are used for protection and they are used by law enforcement to detect contraband and all prohibited items.
Further organised military was used and then it separated into the military force and the police force for years to come. The police were very useful in not only prevention of crimes by patrolling regularly but also by investigating, catching the perpetrator and returning the goods to the rightful owners. Many polices station began forming as their popularity grew.
The mid-19th century saw the development in alarm systems. Alarm systems are popular and can be found anywhere today for low prices. Alarm system Gold Coast, Sydney, New York, London and Johannesburg are some of the cities where alarm systems are very popular.
Private security also was another important evolution in security where private houses were began to hire and use them to guard. Private security was available from historic times but was mostly used by royalty. From the 20th century onwards private security grew considerably.
Video surveillance, CCTV and home alarm systems dominates the security industry today. These systems are popular as they can even alert the authorities and record the whole incident therefore very useful for the police to identify the perpetrators. In the future we may have even more secure systems and that may give us complete and even more reliable security.
