What is CCTV ?
CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
CCTV relies on strategic placement of cameras, and observation of the camera's input on monitors somewhere. Because the cameras communicate with monitors and/or video recorders across private coaxial cable runs or wireless communication links, they gain the designation "closed-circuit" to indicate that access to their content is limited by design only to those able to see it.
Why is CCTV Important?
Maintaining perimeter security in medium to high secure areas.
Building and ground security.
Obtaining a visual record of activities in situations where it is necessary to maintain proper security or access controls.
Types of Camera
In an analog camera system, the camera captures an analog signal and this is transferred via a coax cable to the DVR (Digital Video Recorder). The DVR converts the analog signal to a digital one, compresses it and this is stored on a hard drive within the DVR. The footage can be viewed on monitors attached to the DVR or the signal can be sent across a network to be viewed on a computer screen.
With digital IP (Internet Protocol) cameras, each camera captures an analog signal, but this is converted to a digital signal within the camera itself. The digital signal is then sent via a LAN (Local Area Network). For IP cameras, the video from each camera is compressed and recorded onto an NVR (Network Video Recorder). The key difference is that the signal is digital and a much higher resolution than analogue.
