Up until the 1980s, watchman was the most common term used to describe someone keeping watch over a location or property, a term dating back to at least the European Middle Ages. Today, they are more aptly called security guards. Security guards Sydney are required to be licensed, as per the laws of Australia governing security related fields. The license management for these security services are varied depending on state or territory. In some the management is carried out by the police, in others, it is handled by the justice department.
Security officers usually wear uniforms, and act to protect property and deter theft by maintaining a highly visible presence in the area. Their work can consist of various acts and measures depending on the location and employe. They can patrol, watch alarm systems or video cameras, or can report incidents to emergency services or security companies Sydney when necessary.
Security companies Sydney are allowed to have their security guards carry firearms, batons or handcuffs only when their role requires them to, and only when they are working with the appropriate sub class accreditation on their license. Initially, security companies Sydney and their personnel outnumbered police. After the Security Industry Regulation Act of 2007, however, the number has dropped to half security personnel that were noted in a 2006 statistics report.
