Whois & Analysis for active-vision.com

Closed-circuit television (CCTV), also known as video surveillance, is the use of video cameras to transmit a signal to a specific place, on a limited set of monitors.

It differs from broadcast television in that the signal is not openly transmitted, though it may employ point to point (P2P), point to multipoint (P2MP), or mesh wired or wireless links.

Though almost all video cameras fit this definition, the term is most often applied to those used for surveillance in areas that may need monitoring such as bars, banks, casinos, schools, hotels, airports, hospitals, restaurants, military installations, convenience stores and other areas where security is needed.

Videotelephony is seldom called "CCTV" but the use of video in distance education, where it is an important tool, is often so called.

A digital video recorder (DVR) is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device.

The term includes set-top boxes with direct to disk recording, portable media players and TV gateways with recording capability, and digital camcorders.

Personal computers are often connected to video capture devices and used as DVRs; in such cases the application software used to record video is an integral part of the DVR.

Many DVRs are classified as consumer electronic devices; such devices are sometimes referred to as personal video recorders (PVRs).

An area of computer vision is active vision, sometimes also called active computer vision.

An active vision system is one that can manipulate the viewpoint of the camera(s) in order to investigate the environment and get better information from it.

Security is the degree of resistance to, or protection from, harm.

It applies to any vulnerable and/or valuable asset, such as a person, dwelling, community, item, nation, or organization.

Surveillance (or) is the monitoring of the behavior, activities, or other changing information, usually of people for the purpose of influencing, managing, directing, or protecting them.

This can include observation from a distance by means of electronic equipment (such as closed-circuit television (CCTV) cameras), or interception of electronically transmitted information (such as Internet traffic or phone calls); and it can include simple, no- or relatively low-technology methods such as human intelligence agents and postal interception.

The word comes from a French phrase for "watching over" (sur means "from above" and veiller means "to watch"), and is in contrast to more recent developments such as sousveillance.
