Abstract

Methods and apparatus, including computer program products, for controlling a Pan-Tilt-Zoom (PTZ) camera. A video stream is provided by the PTZ camera. The video stream includes a main image and a smaller picture-in-picture overlay. The main image and the overlay show the same view. The overlay has both a higher frame rate and a lower resolution compared to the main image. A movement control instruction is received, by the PTZ camera, in response to an evaluation of at least one of the main image and the overlay.
