Understanding Auto Focus Settings for BirdDog X1 and X1 Ultra PTZ Cameras

Understanding Auto Focus Settings for BirdDog X1 and X1 Ultra PTZ Cameras

The BirdDog X1 and X1 Ultra PTZ cameras are highly versatile devices equipped with advanced Auto Focus (AF) capabilities designed to deliver exceptional clarity and adaptability in a variety of filming environments. Navigating the Auto Focus settings efficiently can make a significant difference in your video production quality. Within the WebUI under CAMCONTROL/ADVANCED, there are three key sections that control the Auto Focus behavior: SceneAF Zone, and AF Sensitivity. Let’s break down each of these sections for optimal use.

1. Scene Settings


The Scene setting determines the camera’s approach to focusing based on the type of environment and subject you are working with. There are three modes available:

  • Normal: This mode is recommended for most general use cases. It provides a balanced approach to focusing that works well for typical shooting scenarios, delivering reliable focus on both subjects and background elements.

  • Macro: Ideal for extreme close-up shots, Macro mode allows for much finer focus on objects that are positioned very close to the camera. This is especially useful for capturing intricate details or for situations where the subject is within a short distance of the lens.

  • Live: This setting is tailored for smaller studio spaces where distinguishing between a presenter and the background is crucial. The Live mode enhances the camera’s ability to detect and focus on the primary subject, ensuring that the presenter stays sharp even if there are background elements in the frame.

2. AF Zone Settings


The AF Zone setting lets you define the specific region of the frame where the camera should prioritize focus. This customization helps direct the camera’s attention to the desired part of the scene:

  • All: Focus is distributed across the entire frame, allowing the camera to evaluate all areas equally when determining the focal point. This is useful when the subject may move around or if there are multiple points of interest.

  • Top: The camera prioritizes the upper section of the frame for focusing. This can be particularly helpful when filming taller subjects or capturing content that is positioned higher up.

  • Center: Focus is concentrated in the middle of the frame, which is ideal for standard shots where the main subject is centrally located.

  • Bottom: The camera focuses on the lower portion of the frame, beneficial for capturing scenes where the subject is positioned closer to the ground or in the lower third of the shot.

  • Left: Emphasizes focus on the left side of the frame, which can be useful for artistic compositions or when the primary subject is positioned off-center to the left.

  • Right: Directs the focus to the right side of the frame, ideal for capturing scenes where the main subject is positioned on the right side.

3. AF Sensitivity Settings


The AF Sensitivity setting controls how quickly and responsively the camera adjusts its focus when there is a change in the scene. This parameter can be fine-tuned according to the type of movement or speed of focus changes required:

  • Low: The camera responds more slowly to changes in focus. This setting is suitable for scenarios where maintaining stable focus is more important than quick shifts, such as in interviews or when capturing minimal movement.

  • Middle: A balanced approach that offers a moderate response to changes. This setting works well for most general-purpose filming situations, providing reliable focus adjustments without being overly reactive.

  • High: The camera responds rapidly to any changes in focus. This setting is best used in dynamic environments where subjects may move quickly or where immediate focus adjustments are needed, such as in live sports or action scenes.
