What CCTV means?
CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
What is the difference between CCTV and surveillance camera?
Security cameras, also known as CCTV cameras, are used to convey signals from one particular place to a monitor situated at a distance, whereas surveillance cameras normally work on IP networks which link the camera from the remote area to the assigned security location.
Why is it called CCTV?
CCTV relies on strategic placement of cameras and private observation of the camera's input on monitors. The system is called "closed-circuit" because the cameras, monitors and/or video recorders communicate across a proprietary coaxial cable run or wireless communication link.
How CCTV is used for security?
Closed Circuit Television Cameras (CCTV) have become an important crime prevention and security measure. Cameras collect images and transfer them to a monitoring-recording device where they are available to be watched, reviewed and/or stored. CCTV is a situational measure that enables remote surveillance of a locale.
How do CCTV systems work?
CCTV works by the camera or cameras taking a constant sequence of images that are then transmitted by cable or wirelessly (depending on the chosen system type) to the recording device and then on to the display monitor, which enables an individual to see the sequence of images as video footage.
