6.3.1 Image Setting
Image Enhancement:
The image enhancement controls consist of standard video settings, which you know from a
great variety of products. Click on “Video” to see the camera live video while you adjust the
settings to your liking.
White Balance:
Color Tone- Choose between “Real,” “Cool” or “Warm”. Normally you want to set this to
“Real” as it provides the best representation of natural colors.
Auto White Balance- This parameter controls how the camera interprets colors. You
can choose from the following values: “Auto,” “Fluorescent,” “Incandescent,” “Sunny,”
“Cloudy” or “Sun Shade.” You should select the value that best represents the
environment the camera is installed in. You can also leave the default value “Auto,” as it
typically delivers very good results.
Exposure Setting:
Exposure Frequency-
There are four values: “Auto,” “50Hz,” “60Hz” and “Hold
Current.” If your camera is installed so that it’s facing outside, you should select “Auto.”
If your camera is installed indoors, you must select the appropriate light frequency
(either 50 or 60 Hz; e.g., in the US select 60 Hz, in Germany, Poland or Italy select 50
Hz). The hold current option fixes the current exposure settings.
Automatic Exposure- You can manually set the exposure value, which ranges from
0-100 (dark to bright). The default value is 25 and typically provides good results.
Exposure Time- You can define the minimum and maximum exposure time of the
camera’s shutter here. We recommend using the smallest exposure time (e.g., 1/10000
sec) for the min value as it ensures the camera will generate crisp images during day
time conditions in which even moving objects appear sharp and in focus. As for the max
value, the bigger the value, the longer the camera keeps the shutter open in low light
conditions allowing more light to fall onto the image sensor. As a result, the camera can
capture images even in very dark environments. The downside is that moving objects
will appear blurred as the move while the camera’s shutter is open.
Gain- The ZAVIO camera is equipped with an electronic gain mechanism which helps
capture image in dark conditions. The higher the gain, the brighter the image, but the
downside is that the image contains more noise.
Low Light Behavior- When enabled, this opens allows additional control over the
camera when it is running in night mode.
Backlight Compensation (BLC)- In images where a bright light source is behind the
subject of interest, the subject would normally appear in silhouette. BLC allows the
camera to adjust the exposure of the entire image to properly expose the subject in the
foreground. The resulting image may appear overexposed in the background; however,
