A spy camera is a device that is capable of capturing video (and sometimes audio) of a location without the subjects' knowledge. Although they are occasionally used for commercial purposes, spy cameras are mainly used for surveillance activities.
Spy cameras are also sometimes known as nanny cameras or nanny cams, due to the common use of spy cameras in checking on caregivers' treatment of children.
Spy cameras are usually disguised as ordinary objects in the environment of the business or home. Different types of spy cameras exist, and some are designed exclusively for certain environments, although most are designed to suit all environments. Spy cameras can be either wired or wireless. A wired spy camera is connected to a storage device, whereas wireless transmits the recording to a receiver within a small radius.
Spy cameras are considered of great help in protection, safety and even investigations. They are frequently used by law enforcement and even in business environments to provide evidence of theft or misconduct. Security officers use spy cameras to monitor activities and scenarios often not possible with standard audio/video equipment.
Spy cameras, if not used properly, can cause a violation of rights. Employees could feel discomfort or even distrusted by employers if they discover spy cameras, potentially leading to an unhealthy working relationship. In other environments, they could be used to restrict privacy or even exploit people.
