Exposure control:
■
Exposure level: You can manually set the Exposure level, which ranges from -2.0 to +2.0 (dark to
bright).
Flickerless: Under some circumstances when there is a differnece between the video capture
frequency and local AC power frequency (NTSC or PAL), the mismatch causes color shifts or ickering
images. If the above mismatch occurs, select the Flickerless checkbox, and the range of Exposure
time (the shutter time) will be limited to a range in order to match the AC power frequency. See the
screen capture below.
You can click and drag the semi-circular pointers on the Exposure time and Gain control slide bars
to specify a range of shutter time and Gain control values within which the camera can automaticallly
tune to an optimal imaging result. For example, you may prefer a shorter shutter time to better capture
moving objects, while a faster shutter reduces light and needs to be compensated by electrical
brightness gains.
When completed with the settings on this page, click Save to enable the settings.
If you want to congure another sensor setting for a schedule mode, please click Prole to open the
Prole settings page.
Please follow the steps below to setup a prole:
1. Check Enable and apply this prole.
2. Select the applied mode: Schedule mode. Please manually enter a range of time during which the
Schedule mode will apply.
3. Congure Exposure control settings in the folowing columns. Please refer to the previous page for
detailed information.
4. Click Save to enable the setting and click Close to exit the window.
■
WDR:
Enable WDR enhanced:
This function allows users to identify more image details with an extreme
contrast from an object of interest with one shadowed side against a bright background, e.g., an entrance.
You may select the Enable WDR enhanced checkbox, and then adjust the strength (low, medium, high)
to reach the best image quality.
■
AE Speed Adjustment:
This function applies when you need to monitor fast changing lighting conditions. For example, the
camera may need to monitor a highway lane or the entrance of a parking area at night where cars
passing by with their lights on can bring fast changes in light levels. The same applies if the camera is
installed on a vehicle, and when it needs to adapts to fast changes of light when entering and leaving a
tunnel.
