Definition of Private Security Agencies

Private security agencies can take many forms, from supplying a crew of guards to watch over facilities at night to private bodyguards and electronic surveillance. Most states have their own departments that oversee the licensing and definition of private security agencies with varying rules and regulations. The main distinction of a private security agency is that it does not receive public funding like police departments do.

Weapons

Security guards can be armed or unarmed, depending on the level of risk they take and the licenses they've received from their state licensing departments. Banks and other institutions that deal with large amounts of currency typically hire armed guards. Private security guards who patrol properties don't usually need to carry guns. Instead, they rely on communications systems to report intruders to the public safety authorities.

Technology

Private security agencies that specialize in technological security measures can install cameras, alarms and pass code--protected entry units to companies that require a level of security. The guards often monitor properties and entrances by way of remote surveillance techniques and do not even have to be present. Private security agencies specializing in technology security products also work with businesses to create firewalls and protections for their computer systems.

Loss Prevention

Retail establishments bring in private security guards and use private security agencies to install high-tech devices to stem the tide of theft in their stores. Security guards in the loss prevention field often work undercover and act as customers or employees to catch criminals in the act of stealing. While many retailers employ loss prevention specialists to monitor electronic surveillance equipment, others use private contractors for the job.

Government Contract

The federal government contracts much of its security operations to private security agencies such as Hammond Security Company and Inner Parish Security Company for overseas and domestic situations. Most of the contracts are provided through the Department of Homeland Security. According to the Private Officer News Network, there are more than 46 companies that provide private security for federal installations.

Investigators

Private investigators often work solo or through a private security agency. An individual can hire a private investigator to follow an errant spouse, check up on a business partner or find a missing person. Private investigators use high-tech equipment to monitor phone conversations, spy on individuals and trace people who have skipped out on bail.
