Today’s video surveillance cameras have made “leaps and bounds” in technological improvements compared to the cameras from just 10 to 15 years ago.  Not only that, but the camera’s prices have steadily decreased with the increase in technology.  All of this has lead to video surveillance cameras becoming a “household word” for family protection and safety as well as business protection and workplace documentation.

Original video surveillance cameras were based on analog signals.  These systems and components of the systems were often referred to as CCTV or Closed Circuit TeleVision.  CCTV was so named because although it closely resembled a typical television studio system, there was one major important difference.
