CCTV on the other hand, consisted of a circuit of one or more cameras, each connected to a video recorder by means of a video transmission cable.Since most of our monitors that are manufactured today are no longer CRT type but are more commonly LCD (liquid Crystal Display) or LED (Light Emitting Diode), it would see logical that over time, the TVL descriptor will eventually lose out to the more familiar digital “pixel” resolution (for example 720 X 340 pixels), but for the time being, it is well enough that you are aware that the difference exists.e. This allows for finer detail in the image. Closed Circuit Television or CCTV got its name way back in the days of analog transmissions.Since the original video security systems were analog and were called CCTV camera systems, there may be some confusion or crossover that exists today when describing digital video systems. If you are interested in such a system, it will serve you well to do some research before venturing out to make your fist purchase. Generally speaking, the more pixels in a video for a fixed area, the greater the detail of the video because the dots are much smaller. A typical video security system was referred to as a Closed Circuit system because the cameras did not broadcast their signals to the open public. These cameras were basically smaller versions of the cameras used in television studios.” A CCTV camera system is simply a digital video camera system that normally includes a Digital Video Recorder and a display monitor. The CRT monitor displays a picture by rapidly projecting horizontal lines across the screen; the more horizontal lines per fixed vertical area, the greater the detail or resolution of the video.First a little history. At Security Camera King, we encourage you to shop around, because we know that we offer the highest quality systems and the best possible prices. Today’s systems are entirely digital and the systems are component systems, meaning that when putting together your system, you can choose different pieces of the system that have different functions to tailor fit the system to your needs.Since the data is digital, many of the individual electronic components of a modern CCTV camera system are the same things used in personal computing. Analog CCTV camera systems recorded their video on magnetic tape, usually VHS or Beta format. When a loop tape reached the end of the tape, it simply continued over again on the beginning of the tape, re-recording over the original.Today, CCTV camera systems are digital.So where’s the confusion? Today you may still see CCTV camera systems that describe their clarity or detail or resolution of the camera in terms of Televsion Lines or TVL. The camera data is compiled into a digital video file which can either be stored on a hard drive disk or other storage media and/or viewed on a digital monitor. For more information on determining the equivalencies of resolution for these systems see the articles in our knowledge base.

These days there are more Closed Circuit TeleVision or CCTV camera systems than applications for their uses. The used tape had to be ejected and a new one put in place every few hours or a “loop” tape was used.Digital video is not displayed in horizontal lines, but as a series of horizontal and vertical dots called pixels. anyone that had a receiver or television).You may be asking what is meant by the term “CCTV Camera System. For example, the computer Hard Disk Drive or HDD is the major constituent of the DVR storage. For example, analog CCTV cameras displayed their video on older CRT (cathode ray tube) type television monitors. Instead of sending their video transmissions in analog type signals, they are sent in binary or digital form, usually in the form of bits or bytes, the same sort of digital segments used by personal computers. These pixels may be circular or square in shape. A computer processor, much like the Central Processing Unit or CPU of a personal computer compiles the digital video files, controls and coordinates camera activity as well as playback and other DVR functions. Yet other cameras may describe their resolution in terms of pixels.
