Spy surveillance equipment is one of the chief surveillance tools used in organizations such as the CIA and the FBI. It is also available to the general public. People install state-of-the-art surveillance equipment to keep an eye on their valuables or to alert them to any intruders on their property.

Spy surveillance equipment is sometimes so small that it is virtually invisible to the human eyes. Commonly available spy surveillance equipment includes nanny, hidden, regular, digital, pinhole, and wearable spy cameras.

Spy cameras are small cameras that can be used for many purposes, especially for security measures. Spy cameras are installed in many business organizations to monitor employees. This helps the company owners to catch thieves in the act, save money, and, in some cases, prevent abuse of other employees on the job.

Spy surveillance equipment boom is extending fast to the home front as well. Parents use the spy surveillance equipment to keep a watchful eye on the nannies, and thus ensure protection of their children. To monitor telephone conversations, there are quite a few spy surveillance options available, such as spy phone recorders, digital phone recorders, cell eavesdropping equipment and wiretapping devices.

A number of companies now manufacture sophisticated spy surveillance instruments that are now increasingly used by the general public. Sometimes, this spy equipment is used for illegal activities such as extortion and blackmail. These incidents are few and far between, and surveillance tools are usually used to keep people safe. An important thing to remember is that though the use of spy equipment and devices is mostly legitimate, the user has to necessarily confirm whether his/her countrys or states laws allow using it.
