Correct colour rendition and stable white balance are essential for professional video. This chapter explains each white balance mode, how to fine-tune colours, boost saturation, and—if you have the CCM license—match your camera to other systems.

White Balance Modes

  • Auto – Continuously measures and adjusts to changing light conditions.
  • Manual – Use RG/BG sliders to add or remove red/blue bias when lighting is consistent.
  • XX00 K – Lock white balance to a specific Kelvin temperature (e.g. 5600 K for daylight).
  • OnePush – Calibrates white balance on a white card in the frame, then locks it until changed.

OnePush White Balance

OnePush gives the most accurate, repeatable white point:

  • Web GUI: VIDEO ▶ Camera Settings ▶ Color ▶ WB Mode ▶ OnePush
    • Place a white card to fill the frame and click Adjust.

  • OSD menu: MENU ▶ CAMERA ▶ COLOR ▶ WB Mode ▶ OnePush
    • Press HOME to begin calibration.

  • During calibration the camera measures the white reference and locks the white balance:

Adjusting Colour Saturation

Why: IP streaming often reduces colour richness. Boost saturation to restore vibrancy.

  • OSD menu: MENU ▶ CAMERA ▶ COLOR ▶ Saturation
  • Web GUI: VIDEO ▶ Camera Settings ▶ Color ▶ Saturation
  • Recommended: 120 % – 130 %

Auto White Balance (AWB) Sensitivity

This determines how quickly the camera responds to changing light:

  • High – fast adjustments, may cause flicker in mixed lighting.
  • Mid – balanced response.
  • Low – slow adjustments, helps prevent “pumping” in low light.

Customizable Color Matrix (CCM)

If you’ve purchased the SRT & CCM license, an extra CCM tab appears. The 3×3 matrix lets you match colours across camera systems.

CCM - Customizable Color Matrix

Channels & Signals

The matrix has horizontal Channels (source RGB) and vertical Signals (output RGB). Adjust cells to add or subtract colour components.

Signals and Channels in CCM

  • Channel – row = source colour component.
  • Signal – column = output colour addition/subtraction.
  • CCM total – sum of R+G+B per column; turning red if not 256 (you can ignore).

Subtracting Colours

Use values above/below zero to remove a colour:

  • Green > Red = +256 removes red from green areas, adding a green tint.
    Red and yellow parts green
  • Green > Green = +256 removes green, reducing overall intensity.
    Without the greenish tint

Remember: +256 = lighter, −256 = darker overall.

Adding Colours

Use a + value in one cell and − in another to add a colour:

  • Blue > Red = +256 and Blue > Blue = −256 adds blue, yielding purple tones.
    +256 red and -256 blue
  • Blue > Red = −512 and Blue > Blue = +512 adds red, shifting hues.
    -512 red and +512 blue

Best practices

  • Use OnePush white balance whenever possible.
  • Boost saturation to 120 %–130 % for IP streaming.
  • Use CCM to harmonise colours in multi-camera setups; calibrate with colour cards.
  • Re-run white balance after significant lighting changes.
