An innovation to the PTZ camera is a built-in firmware program that monitors the change of pixels generated by the video clip in the camera. When the pixels change due to movement within the cameras field of view, the camera can actually focus on the pixel variation and move the camera in an attempt to center the pixel fluctuation on the video chip. This process results in the camera following movement. The program allows the camera to estimate the size of the object which is moving and distance of the movement from the camera. With this estimate, the camera can adjust the cameras optical lens in and out in an attempt to stabilize the size of pixel fluctuation as a percentage of total viewing area. Once the movement exits the cameras field of view, the camera automatically returns to a pre-programmed or "parked" position until it senses pixel variation and the process starts over again.
