Video cameras are also designed for specific light-levels and applications. Some cameras are very sensitive to infrared light and therefore perform well in low or no-light situations. Some of these cameras are so sensitive to the infrared that they can be used in no visible light conditions in conjunction with an artificial source of infrared illumination. What ever your camera is viewing will be diplayed on your video monitor. Likewise, whatever your system has recorded in the past will be played back on your monitor.
Video monitors are similar to television sets only in their general appearance.
A device known as a RF Converter is required. Your application and the amount of detail you require to see from your video system will determine the video monitor that should be incorporated into the design of your system. There are a few exceptions to this, and they generally are associated with the video kits or package systems. Let us discuss real time recorders first. These recorders are a relatively new entry into the CCTV market.
