Security guards - commonly referred to as bouncers, mall cops and security officers - possess limited legal powers depending on the laws in your jurisdiction. Under some circumstances they may interfere with privacy rights, arrest people and detain people.

However, they must immediately deliver an arrested person to police. Physical force may also be used if necessary in order to uphold venue's rules and fulfill legislative requirements like Liquor Act 1992. https://zsecurityguards.com.au/
They can detain people

Security guards can detain people on reasonable suspicion that a crime is being committed and search their bags or pockets to verify this suspicion. This often occurs in stores when loss prevention personnel accuse shoppers of shoplifting; but similar procedures may take place at hotels, restaurants and nightclubs as well.

Keep in mind, however, that security guards are not law enforcement officers and should never act like them. Doing so may have serious legal repercussions for both them and their employer.

Security guards must have a legitimate reason before arresting someone and should contact the police as quickly as possible if someone is arrested by them. If this occurs to you, immediately request legal representation and be mindful of what you say as security guards could use any statements they hear against you in court proceedings. Furthermore, they have access to search lockers on private property without prior permission of its owners.
They can make a citizen’s arrest

Security guards can make arrests on anyone they believe has reasonable and valid suspicion. When arresting a suspect, the guard must inform them why they're being taken in for arrest and must only use force that is absolutely necessary in making the arrest. They may use techniques such as pincer or grab arrest to effect this.

Private security guards may make citizen's arrests when witnessing criminal behavior and have reasonable cause to suspect that the suspect will commit further offenses or damage property. They should detain them using restraint before calling law enforcement immediately. They must release them once there is no longer any cause for their detention or law enforcement arrives on scene.

Security guards need to understand their power and respect the rights of their targets without mistreating anyone. Trespassing, using excessive force or using racist epithets are illegal acts and could incur legal ramifications for themselves and their employer; for this reason it's imperative for security personnel to remain calm in all circumstances while acting professionally at all times.
They can monitor alarms and CCTV

Security guards are responsible for keeping an eye on who enters and leaves their employer's property, recording all activity including theft or criminal damage to keep track of activity at their employer's establishment. Security guards often work closely with law enforcement officials in preventing crime by reporting suspicious activities to authorities.

Security officers can monitor alarms and CCTV to quickly respond to potential threats on client premises, while patrolling remotely for cameras to reduce costs for clients.

As humans can only ever be one place at once, security guards remain vulnerable to distraction and complacency - particularly on late-night shifts alone. Proactive video surveillance can reduce these issues and ensure your site is always monitored even when staff members are off site or away on vacation. Security guards can also serve as invaluable assets during crises by being present constantly and acting as deterrents against potential thieves or vandals.
They can carry out drills

Security guards perform patrol and inspections at private or public facilities to deter theft, fire, vandalism, trespassing or acts of terrorism. They monitor alarms and CCTV to detect suspicious activity; depending on client needs they may also carry weapons for protection.

Security officers have the authority to eject people from a property and contact law enforcement when necessary, though they should use extreme caution as unnecessary force could create legal risks for their employer. Drills should also be conducted regularly so security officers have a thorough understanding of their duties.

Many employers provide on-the-job training for security guards. For those considering becoming one, Bryant & Stratton College offers a Criminal Justice and Security Services Diploma program with courses such as Law Enforcement & the Multicultural Community that could improve job prospects. UGSOA specializes in organizing security workers while Service Employees International Union also attempts to organize them.
