Pan-Tilt-Zoom or PTZ Web cameras bring two powerful punches to the benefit of the digital video security and surveillance world. Not only can these cameras allow your system to reap the powerful benefit of camera movement (the first punch) but also make use of the Internet as a means for networking (punch number two).
PTZ cameras have been used in the video security and surveillance world for quite some time; even when the systems operated in a totally analog format. However, as technology has increased, cameras have become more powerful in function and lighter in weight as well as more versatile in application. Now, digital video cameras with PTZ functions are much more easily controlled.
