PTZ is an abbreviation for pan, tilt and zoom. This reflects the movement option of the camera. It is therefore a camera that is capable of remote, directional and zoom control. PTZ controls are commonly used in television studios with professional video cameras. They are not so difficult to use because they can be controlled by automation systems. These controls are usually sold separately without the cameras.
There are various kinds of PTZ cameras that come with different functions. One of them is GeoVision GV-PTZ010D 10x D1 H264 PTZ IP Security Camera. These cameras are always used in situations where a person or an object needs to be tracked. The camera can be automatically moved between present positions. These are the high-speed dome cameras that feature endless 360o panning and high-speed dome cameras that feature up to 400o in a second positioning. They are available in indoor and outdoor models. This feature helps them to monitor live applications where robust camera control is required. Geovision PTZ cameras are also widely available in wireless models, and they also offer indoor PTZ cameras with desktop or ceiling mount applications.

GeoVision GV-PTZ010D 10x D1 H.264 PTZ IP Security Camera is a ceiling-mount device that provides panning, tilting and zooming functions. The camera is designed to monitor a wide area and also to focus on a specific part on the live view when suspicious events occur. There are two models:
|GV-PTZ010D||GV-PTZ010D-N||NTSC, IPCAM, 10x Optical Zoom, D1, H.264|
|GV-PTZ010D-P||PAL, IPCAM, 10x Optical Zoom, D1, H.264|
The other type of a PTZ camera is the PTZ550X27IR 7 IR high speed dome camera All-in-one 36 PTZ camera. It has an IP66 rating. The IP66 rating has an aluminium tilt head with a wide rotation angle into one compact system. It also integrates a zoom block camera. PTZ550X27IR 7 IR high speed dome camera

All-in-one 36× PTZ camera is mostly used for city surveillance, traffic monitoring, on the borders and other crucial infrastructures. It provides a much wider and more flexible viewing angle, unlike the traditional PTZ dome cameras. This camera produces high resolution images at 550TVL and offers precise color reproduction performance. It also responds quickly to capture the emergency scene. This is because it has a 36× zoom lens that produces a full picture of the emergency scene.
A PTZ camera performs an vital function of monitoring the change of pixels generated by the video clip in the camera. This is because of the in-built firm ware program. This program performs a task of allowing the PTZ camera to estimate the size of the object that is moving and the distance of the object from the camera. This enables the camera to adjust its optical lens in and out for stabilization. Once the movement is out of sight of the camera’s field of view, the camera automatically returns to its original position until it gets to sense pixel variation. The process therefore starts all again.
