Network PTZ cameras let users enjoy a 360 degree coverage area just like CCTV PTZ cameras. There are several reasons why a network PTZ camera is different from a CCTV PTZ camera, however. A network PTZ camera can serve as a standalone surveillance system using network infrastructure as its backbone for transmitting high resolution video to computer. Network PTZ cameras can also integrate with large surveillance systems to work together for a truly advanced monitoring system. Network cameras, unlike CCTV cameras, are smart. Network cameras are like tiny computers. They have an interface which is highly configurable to let users predefine a cameras behavior. Along with all the features of a traditional PTZ camera, a network point tilt zoom camera has a wide range of features. Traditional surveillance systems require several sets of cables for data, video, and audio communications. Additionally, other components might be required at the head end (DVR side) for it to work together. An IP camera has most of those features built in so that a single cable is required for transmission. PTZ cameras on a network have input/output ports, audio recording capabilities, and high definition sensors. The combination of high definition sensors and long range zoom lenses make IP PTZ cameras the absolute best option for image clarity. They can also be configured for FTP upload and some have SD card readers for short clip storage. Features like masking let users pick which parts of a coverage area to ignore for movement. For example, if a there is an area with trees which are constantly being moved from the wind, a user can enter the interface of the camera and filter that area out using a mouse. Auto tracking is another powerful feature which some cameras carry to follow an object based on pixilation or movement. Since network cameras have built in processors which are powerful, they relieve a recorder by handling most of the processing by the time it gets to the recorder. Some cameras have SDKs which allow more advanced users to interface their cameras with their own software for engineering purposes.
