Therefore, the camera then follows the movement, estimates the size of the object and its distance from the camera. This is done in an attempt to center the pixel fluctuation on the video chip. In the field of view, when pixels change due to movement, the camera focuses on the variation and moves the camera accordingly. One of the most exciting innovations inherent to PTZ cameras is a built-in program that monitors the change of pixels within a video clip in the camera. With their 360⁰ range of view, all blind spots are removed. Fixed cameras, even multiple fixed cameras, cannot monitor larger areas to the extent of PTZ cameras. The range of movement and the ability to change focus and adapt to specific situations make this camera one of the most versatile available. PTZ cameras have internal, mechanical components that allow both the camera and lens to move. Often associated with high-end security systems common to banks, airports, and corporate headquarters, the cost of SCW’s professional-grade PTZs now makes them affordable enough for small businesses and homeowners to add them to their surveillance systems. With zoom capabilities from 4x to 36x, they give complete control over an entire surveillance area. Whether seeing large and far off areas by zooming in or out, spinning 360⁰, or tilting up and down, SCW’s IP PTZ cameras are fun to use. PTZ cameras (Pan, Tilt, and Zoom), are sophisticated and advanced components of the security system industry.
