PTZ Camera Video & Image Parameter Guide

The Video Parameters menu allows you to fine-tune the PTZ Camera’s image quality and performance for different environments. You can view a live preview while adjusting these settings, making it easy to see changes in real time.

The menu is divided into six key sections:
Focus, Exposure, Color, Image, NR (Noise Reduction), and Style.

1. Focus

The focus settings control how the camera determines and maintains image sharpness.

Parameters

• Focus Mode:
  
  
  • Auto: The camera continuously adjusts focus automatically.
    Recommended for: dynamic environments, presenters moving within the frame, or general-purpose use.
  • Manual: Focus is adjusted manually through the web interface or remote control.
    Recommended for: static shots, product demos, or precise focus control in controlled lighting.
  • One Push: The camera performs a single autofocus operation, then locks focus.
    Recommended for: scenes with minimal subject movement where quick setup is needed.
    
    
• AF Zone:
  
  
  • Top, Center, Bottom, All – Defines which part of the frame is prioritized for autofocus.
    Recommended use:
    
    
    • Top/Bottom: For presenters standing off-center.
    • Center: For most standard meetings and broadcasts.
    • All: For unpredictable movement across the frame.
      
      
• AF Sensitivity:
  
  
  • Low: Slower refocus rate – best for stable environments.
  • Middle: Balanced option for typical room motion.
  • High: Frequent refocusing – best for active scenes or moving subjects.
    
    

2. Exposure

Exposure settings control how much light reaches the image sensor, affecting brightness and motion clarity. Depending on the Exposure Mode selected, different controls appear.

Modes

• Auto: Camera automatically balances exposure for optimal lighting.
  Recommended for: most indoor environments with consistent lighting.
• Manual: Adjust parameters like Shutter Speed, Iris, and Gain manually.
  Recommended for: professional productions where lighting is controlled.
• SAE (Shutter Auto Exposure): Shutter speed adjusts automatically; other settings are manual.
  Recommended for: maintaining proper motion rendering (e.g., sports, live movement).
• AAE (Aperture Auto Exposure): Iris adjusts automatically; other settings are manual.
  Recommended for: maintaining depth of field consistency.
• Bright: Prioritizes brightness in low-light environments.
  Recommended for: dimly lit rooms where maintaining visibility is the priority.
  
  

3. Color

Color settings determine how the camera interprets and balances colors under different lighting conditions.

Parameters

• WB Mode (White Balance):
  
  
  • Auto: The camera automatically adjusts for color temperature changes.
    Recommended for: dynamic environments with varying lighting.
  • Manual: Manually set color temperature between 2400K (warm) and 7100K (cool).
    Recommended for: studios or controlled lighting environments where color consistency is critical.
  • One Push: Capture a white balance using a white card or neutral object, then lock it in.
    Recommended for: quick calibration before a shoot or meeting.

Tip: Use One Push with a white balance card for the most accurate color tones.

4. Image

These settings refine the look of your image and control orientation or digital zoom.

Parameters

• Brightness: Adjust overall image lightness or darkness.
• Contrast: Increase for sharper visual distinction; decrease for softer tones.
• Sharpness: Enhances edge detail. Too high may introduce noise.
• B&W Mode: Enables black-and-white output for stylistic or low-light conditions.
• Flip-H / Flip-V: Manually mirror the image horizontally or vertically.
  Note: Only available when Auto Flip is disabled.
• Auto Flip: Automatically adjusts image orientation when the camera is mounted upside down.
• DZoom (Digital Zoom): Provides additional zoom beyond optical range.
  Note: May reduce image quality; best for minor framing adjustments.
  
  

Recommended use:

• Use DZoom sparingly for fine framing.
• Enable Auto Flip when installing the camera on ceilings.
  
  

5. NR (Noise Reduction)

Noise reduction settings help clean up the image by minimizing digital noise, especially in low-light environments.

• NR-3D (3D Noise Reduction): Analyzes multiple frames to smooth noise while preserving detail.
  Recommended for: low-light rooms or dim auditoriums.
  Tip: Use moderate levels to balance between clarity and softness — too much NR can blur fine details.
  
  

6. Style

Style presets adjust multiple parameters at once for quick optimization.

Preset Options

• Default: Balanced settings suitable for most use cases.
• Meeting: Optimized for conference rooms with even lighting and skin tones.
• Clarity: Increases contrast and sharpness for crisp detail.
• Bright: Enhances exposure and color vibrancy in dim settings.
• Soft: Reduces contrast for a more natural, less intense appearance.
  
  

Recommended use:

• Meeting: Corporate video calls and classrooms.
• Clarity: Live events, sports, or product shots.
• Soft: Portraits or interviews in harsh lighting.
• Bright: Low-light environments.
  
  

Quick Tips for Best Results

• Always preview changes in real time using the web interface before applying them to production.
• For professional settings, lock focus and white balance once the scene is properly configured.
• When lighting or subjects change frequently, Auto Focus and Auto Exposure modes ensure consistent performance.
