Analog PTZ



PTZ is an abbreviation for pan, tilt and zoom and reflects the movement options of the camera. Other types of cameras are PTZ or virtual pan-tilt-zoom (VPTZ) where a high-resolution camera digitally zooms and pans into portions of the image, with no physical camera movement. Ultra-low bandwidth surveillance streaming technologies use PTZ to stream user-defined areas in higher quality without increasing overall bandwidth usage. Surveillance cameras of this type are often connected to a digital video recorder which records the full field of view in full quality.
