How to Set Image Parameters (WEB 5.0)

Steps to Set Image Parameters

Ensure your device supports the image parameter settings described. This tutorial is based on WEB 5.0 firmware, though interfaces may vary across models and firmware versions.

Operation Description

Login to your device.

Navigate to Camera > Image.

Configure the following parameters:

Page Layout

• Normal Mode, Day Mode, or Night Mode: View and configure settings for different times of day.
• Self-adaptive: The camera adjusts the image according to the environment.
• Customized Scene: Choose the profile that fits your needs. In the Time Plan Setting, select the desired profile and use the slide block to define specific times for that profile. For example, you can set 8:00–18:00 as "Day" and 0:00–8:00 and 18:00–24:00 as "Night."

AI SSA (AI Scene Self-adaptation)

AI SSA (AI Scene Self-adaptation) is a feature that uses artificial intelligence to automatically adjust system settings based on the current scene or environment. This ensures optimal performance and quality by dynamically adapting to factors like lighting and activity. Automatically adjusts image parameters based on environmental conditions such as rain, fog, and low light.

After enabling AI SSA, functions such as exposure, backlight, defog, and AFSA will be disabled by default.

Image

Parameter Description:

• Style: Choose the picture style:
  

  • Soft: Default style, displays the image’s true colors.
  • Standard: Colors are less intense and contrast is reduced.
  • Vivid: Colors are enhanced for a more vibrant image.

• Brightness: Adjust the picture’s brightness. Higher values make the image brighter, while lower values make it darker. Excessive brightness can cause haziness.

• Contrast: Change the contrast between light and dark areas. Higher values increase contrast, which can cause dark areas to be overly dark and bright areas to be overexposed. Low contrast might result in a hazy picture.

• Saturation: Adjust the color intensity. Higher values deepen the color, while lower values lighten it. Saturation affects color but not brightness.

• Sharpness: Modify edge clarity. Higher values make edges clearer but may introduce noise if set too high.

• Gamma: Adjust picture brightness and dynamic range non-linearly. Higher values brighten the image, while lower values darken it.

• Mirror: Click to reverse the picture left and right.

• Flip: Change the display direction of the picture:

  • 0°: Normal display.
  • 90°: Rotate 90° clockwise.
  • 180°: Rotate 180°.
  • 270°: Flip upside down.

  Note: For some models, set the resolution to 1080p or lower for 90° and 180° rotations.

Exposure

Configure the iris and shutter settings to enhance image clarity.

Note: Cameras with true WDR (Wide Dynamic Range) do not support long exposure when WDR is enabled for backlight compensation.

Descriptions of Exposures:

• Anti-flicker: Select the frequency based on your electric supply or environment:

  • 50 Hz: For systems with a 50 Hz electric supply; adjusts exposure to prevent stripes.
  • 60 Hz: For systems with a 60 Hz electric supply; adjusts exposure to prevent stripes.
  • Outdoor: Select any exposure mode as needed.

• Mode: Choose the exposure mode for the device:

  Note: When Anti-flicker is set to Outdoor, you can select Gain Priority or Shutter Priority.

  • Auto: Automatically adjusts image brightness based on conditions.
  • Gain Priority: Prefers gain adjustments; if brightness is insufficient and gain limits are reached, adjusts shutter value to maintain ideal brightness. Configure gain range for this mode.
  • Shutter Priority: Prefers shutter adjustments; if brightness is insufficient and shutter limits are reached, adjusts gain value to maintain ideal brightness.
  • Manual: Manually configure gain and shutter values to adjust brightness.

• Exposure Compensation: Adjusts image brightness with values ranging from 0 to 50. Higher values increase brightness.

• Shutter: Sets the effective exposure time; smaller values mean shorter exposure times.

• 3D NR (Noise Reduction): A feature that reduces noise in video or images by analyzing and filtering noise over multiple frames. This technique helps to improve image clarity and quality, especially in low-light conditions or when capturing high-speed motion.

  • Level: The level setting for 3D Noise Reduction. A higher value increases the noise reduction effect, which can improve image quality but may also reduce sharpness.
  •  
• 2D NR (2D Noise Reduction): A feature that reduces noise by filtering noise in individual frames. This method focuses on improving image quality within a single frame without considering multiple frames.
  • Level: The level setting for 2D Noise Reduction. A higher value enhances noise reduction, improving image quality but potentially blurring fine details.

Backlight 

You can select from the following backlight modes: Auto, BLC, HLC, WDR, and SSA.

 Description of Backlight

• BLC (Backlight Compensation):

  • Default Mode: Automatically adjusts exposure to ensure clarity of the darkest areas against bright backgrounds.
  • Customized Mode: Adjusts exposure only in a specified area to maintain ideal brightness in that area while accounting for ambient lighting.
  • 

• WDR (Wide Dynamic Range):

  • Balances bright and dark areas to ensure overall clarity. Higher values brighten dark areas but may introduce more noise.
  • Note: Switching to WDR mode from other modes may cause a brief video loss.
  • 

• HLC (High Light Compensation):

  • Reduces the impact of extremely bright light sources (e.g., from a toll station or parking lot) to lower the overall image brightness and enhance details such as faces or license plates. Higher values increase the HLC effect.
  • 

• SSA (Scene Self-Adaptation):

  • Automatically adjusts image brightness based on environmental conditions to make objects clearer.

WB (White Balance)

The WB function ensures accurate color representation, making white objects appear white in various environments.

Description of WB Parameters

• Auto: Adjusts white balance based on color temperature to ensure accurate color reproduction.

• Natural: Compensates white balance for environments without artificial light to maintain color precision.

• Street Lamp: Adjusts white balance for outdoor night scenes to ensure accurate color representation.

• Outdoor: Compensates white balance for most outdoor environments, whether natural or artificial light, to ensure color accuracy.

• Manual: Allows manual adjustment of red and blue gain; the system compensates white balance based on color temperature.

• Custom Area: Adjusts white balance only for a specified area based on color temperature to ensure color precision.

Day/Night

Configure how the image display mode switches between color and black-and-white based on environmental conditions.

Description of Day and Night Parameters

• Mode: Choose the display mode for the device:
  

  • Color: Displays the image in color.
  • Auto: Automatically switches between color and black-and-white based on conditions.
  • B/W: Displays the image in black-and-white.

  Note: Day & Night configuration operates independently from profile management settings.

• Sensitivity: Available only if Auto is selected in Mode. Adjusts the camera’s sensitivity for switching between color and black-and-white modes.

• Delay: Available only if Auto is selected in Mode. Sets the delay time for switching between color and black-and-white modes. A lower value results in faster switching.

Illuminator

This configuration is available only if the device is equipped with an illuminator.

Description of Illuminator

• Manual: Allows manual adjustment of illuminator brightness; the system then uses this setting to illuminate the image.
  • Illumination Overexposure Remover (General):
    • Reduces Overexposure: Automatically adjusts image settings to mitigate the effects of strong light sources, preventing areas from becoming too bright.
    • Enhances Clarity: Improves the overall clarity and detail of images by balancing out the illumination levels.

Defog

Defog improves image clarity in foggy or hazy environments by compensating for reduced visibility.

• Manual:

  • Configure the intensity of the defog function and atmospheric light mode manually. The system then adjusts image clarity based on these settings. Atmospheric light mode can be set to adjust automatically or manually.

• Auto:

  • The system automatically adjusts image clarity based on current conditions to counteract fog or haze.

• Off:

  • Disables the defog function.

LDC (Lens Distortion Correction)

LDC is a feature used to correct distortions in images caused by the lens. Distortions can include barrel distortion (where the image bulges outwards), pincushion distortion (where the image pinches inward), and other aberrations that affect image quality.

• Corrects Lens Distortion: Adjusts the image to compensate for lens imperfections, ensuring that straight lines appear straight and the overall image is more accurate.
• Enhances Image Quality: Improves the visual clarity and accuracy of the captured image by correcting for common lens-related distortions.
