How do I adjust the color balance on my CC4620 camera?

To adjust the color balance, select the desired mode using the DIP switches 1 and 2. The default setting is Auto, but you can choose Outdoor, Indoor, or Fluorescent for different lighting conditions.

What is the default setting for the Gamma on the CC4620 camera?

The default setting for the Gamma is Normal 0.45, but you can also choose Linear 1.0 using DIP switch 3 for increased visibility in dark areas.

How can I improve picture quality in low-light conditions with the CC4620 camera?

You can improve picture quality in low-light conditions by turning on the Automatic Gain Control feature using DIP switch 4. The AGC should be ON for most applications.

Are there different color balance modes for different lighting conditions?

Yes, there are four color balance modes selected by DIP switches 1 and 2, including Auto, Outdoor, Indoor, and Fluorescent settings.

Color Balance

There are four color balance modes selected by DIP switches 1 and 2. For the majority of applications the Auto setting will provide excellent color rendition and is the default setting. For applications where the illumination is predominantly daylight, the Outdoor setting may provide improved color rendition over Auto. Where a mixture of illuminations such as tungsten, fluorescent and daylight exist, the Indoor setting may provide the best color rendition. Where fluorescent lighting is predominant, use the Fluorescent setting.

Gamma

There are two different levels of Gamma selected by DIP switch 3. Choose between Normal (0.45) to provide increased visibility in dark areas of the scene, or Linear (1.0). The default setting is Normal.

AGC (Automatic Gain Control)

The Automatic Gain Control feature can improve picture quality when levels of illumination are low. Select ON or OFF using DIP switch 4. For most applications, the AGC should be ON and is the default setting.

LL-PH (Line Lock, Phase Adjust)

The Line Lock, Phase Adjust feature is selected by DIP switches 5 and 6. Choose Fixed or Adjustable. Both settings are line-locked; however, the Adjustable setting allows ±120O phase adjustment via the potentiometer located on the rear of the camera. The Adjustable mode should be used when cameras are connected to different AC power supply phases. Default setting is Fixed.

SYNC (Synchronization)

The Synchronization feature is selected using DIP switch 6. Choose LL (Line- Lock) or Internal. LL locks the frame rate to the power supply frequency so that cameras are triggered at the same point on the power supply AC cycle. Internal locks the frame rate to the internal oscillator of the camera. The default setting is LL.
