It is the use of Videos 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 wireless links. CCTV is often used for surveillance in areas that may need monitoring such as banks, casinos, airports, military installations, and convenience stores.
In industrial plants, CCTV equipment may be used to observe parts of a process from a central control room; when, for example, the environment is not suitable for humans. CCTV systems may operate continuously or only as required to monitor a particular event. A more advanced form of CCTV, utilizing Digital Video Recorders (DVRs), provides recording for possibly many years, with a variety of quality and performance options and extra features (such as motion-detection and email alerts).
Surveillance of the public using CCTV is particularly common in the UK, where there are reportedly more cameras per person than in any other country in the world.[ There and elsewhere, its increasing use has triggered a debate about security versus privacy.

PLAY STATION
The PlayStation is a 32-bit fifth generation video game console released by Sony Computer Entertainment in December 1994.
The PlayStation was the first of the PlayStation series of console and handheld game devices, which was first created and released in Japan. Successor consoles and upgrades include the Net Yaroze, PS one, PSX, PocketStation, PlayStation, PlayStation, PlayStation2, PlayStation Portable, and the PlayStation 3. On March 31, 2005, the PlayStation and PS one reached a combined total of 102.49 million units shipped, becoming the first video game console to reach 100 million.
Functions
The Playstation console, in addition to playing games, has the ability to read and play audio CDs. The CD player has the ability to shuffle the playback order, play the songs in a programmed order, and repeat one song or the entire disk. This function, as well as a memory card manager, can be accessed by starting the console without inserting a game, therefore accessing a system menu with a dark blue background and buttons that are designed like rainbow graffiti. If a game is put in the system at any time on the menu, the game will immediately start.
