Please always make sure, during planning and installation, that the camera's position is chosen based on the desired field of view. For further guidance on camera positioning, please refer to our Designing for VisionSuite Training Guide. 

White Balance Calibration

To ensure accurate color reproduction, it is best to set the White Balance mode to Manual. 

• We strongly recommend using 17% gray card to automatically calibrate the white balance on the camera. 
• To do so, zoom in on the gray card using the PTZ controls, until the gray card fills up the entire frame. 
• Then, click the 'AWB One Push' button to initiate the auto white balance calibration. This takes around 5 seconds.

Exposure Settings

Auto Mode: Make sure to enable the Backlight Compensation setting if backlight is present. 

We recommend lowering the blinds/curtains on external-facing windows to stabilize light levels in the room and reduce glare.

If the image is too bright or dark overall, adjust the Compensation. 

If the image is getting too bright in certain shots, lower the Gain Limit. This can also be used to stop the gain increasing when the camera is pointing at dark areas. 

If the image flickers, turn on the Anti-Flicker function. You can also enable SDI/HDMI output, and set the Frame rate to match your countries Mains AC frequency (e.g. 60Hz for USA and Canada, 50 Hz Europe.

Manual Mode: Where lighting conditions are consistent, we recommend setting the Exposure mode to Manual for more precise control over the image quality. 

• Start first by adjusting the shutter speed. Then, tweak the Aperture and Gain to refine the image brightness. 

1. Shutter speed: aim for a shutter speed that is half of the exposure time. For a refresh rate of 30 Hz this will be 1/60th of a second. If you need more light, then 1/30th is fine, but you will see more motion blur for fast moving objects. 
2. Aperture: a lower number means a wider aperture, which lets in more light. For bright rooms you may want this to be a higher number, but typically the lowest number is good when cameras are used with indoor lighting. Note – this option is not available on the NC-110. 
3. Gain: this is the sensitivity of the sensor. A higher number will make the image brighter but will introduce more noise. 

• Increase Gain until the image is at the desired brightness. If the image is too noisy at this setting, adjust the shutter speed or aperture to let in more light. If this cannot be done, consider your room’s lighting. 
• If the image is too bright with the Gain set to 0, adjust the aperture and shutter speed to let in less light.

Picture Controls:

• Increase the Contrast for a punchier image with more defined shadows and highlights. 
• Adjust the Saturation to achieve the desired color vividness without oversaturating skin tones. 
• Increase the Sharpness to enhance the details (be careful to avoid introducing noise or other artifacts.) 
• To brighten the shadows, increase the Dynamic Range without overexposing the highlights. 
• To reduce image noise, enable the 3D Noise Reduction setting and tweak the amount of noise reduction applied. 
• The higher the noise reduction, the more image detail will be lost and artifacts such as banding could be introduced.

• We recommend setting the Auto Focus Sensitivity to Normal or Low to minimize focus hunting. 
• Be sure to also adjust the Auto Focus Zone to match how your participants are framed in the shots (usually Center or Bottom). 
• To maximize Auto Focus performance, ensure you’re using adequate lighting fixtures to maximize the light level in the room.

• A UCI can show a maximum of two different Mediacast preview streams simultaneously. 
• The preview stream must be enabled in the Camera Component’s Mediacast Streams Tab if you want to see 30fps previews on Q-SYS touch panels and the Windows UCI viewer. 
• When using multiple cameras, be sure to set the Media Display control’s properties. 
• Each video preview control within your UCI is assigned a priority. Adjusting this property is only necessary when you have more than two preview controls (each from a different Q-SYS camera) in a UCI page. 
• Automatic: (Default) This is the lowest priority. At design startup, a preview control with automatic priority will decode live video only if other Media Displays with higher priority are not currently streaming live video. 
• Preferred: This is the middle priority. At design startup, a preview control with Preferred priority will decode live video after those with Fixed priority and before those with Automatic priority. 
• Fixed: This is the highest priority. At design startup, a preview control with Fixed priority will decode live video before those with other priorities.

• Enabling the Auto Framing function will disable the HDMI/SDI outputs. 
• Clicking the 'Reset all camera settings' button will reset the settings to factory defaults.
