PTZ Video Security Cameras
Pan-Tilt-Zoom Security Cameras also known as PTZ
security cameras are excellent devices to use when you want to 'look around' your surveillance area.
PTZ security cameras allow you to pan an entire room, tilt up and down and zoom in on anything or anybody within the sight of the lens.
Also, PTZ video security cameras can be set to automatic or manual mode or both. In automatic mode, hundreds of points can be set for the camera to look at. The duration that the camera looks at a given set point can be adjusted from less than a second to as long as you would like. PTZ Camera
