Surveillance cameras have been in use for decades to deter crime and to capture video evidence to be used in the prosecution of crimes. However, criminals are aware of surveillance cameras and continually attempt to circumvent them, by various means. Taking advantage of human behavior is one way criminals avoid being filmed in a criminal act. Security guards and even homeowners cannot be everywhere at once. Therefore, many surveillance systems are unattended, in other words, the cameras videotape without the benefit of human analysis. The crimes and actions of others are being recorded and preserved, but the acts in some cases are only detected after the fact. However, new technology has once again caught up with the demand. New technology shows us how to benefit from an auto-tracking PTZ. PTZ is an acronym used to describe cameras that can pan, tilt and zoom.
Pan-Tilt-Zoom or PTZ security cameras can really extend the field of view of an otherwise stationary camera. There are a variety of PTZ security cameras that can perform many functions in addition to PTZ perhaps making this camera the most versatile in application of all the different types of security cameras.
