Instant Focus Optimization for PTZ Surveillance Cameras
8 PagesFocus recall is a feature designed to ensure instant and reliable focus in predefined areas, particularly in challenging environments with low contrast, noise, or strong light sources like headlights. Once an area is set, the camera automatically recalls the correct focus whenever the view returns to that region, eliminating delays associated with autofocus adjustments. Unlike presets, it requires no manual selection during operation. This makes it highly effective for scenarios involving frequent manual camera movement, such as traffic monitoring, autotracking, and guard tours, improving efficiency and image clarity.
