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 Intellinet 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, the object of interest is now properly
lit.
