Illumination angle
from the camera's angle of view. If the camera has a wide angle of view, you can set the illumination angle to a narrower angle,
which equals a greater tele position. This will result in dark corners in the image.

Exposure
Select an exposure mode to reduce rapidly changing irregular effects in the image, for example, flicker produced by different types of
light sources. We recommend you to use the automatic exposure mode, or the same frequency as your power network.
Exposure mode:
• Automatic: The camera adjusts the aperture, gain, and shutter automatically.
• Automatic aperture
• Automatic shutter
• Hold current: Locks the current exposure settings.
• Flicker-free
speeds: 1/50 s (50 Hz) and 1/60 s (60 Hz).
• Flicker-free 50 Hz
• Flicker-free 60 Hz
• Flicker-reduced
1/100 s (50 Hz) and 1/120 s (60 Hz) for brighter scenes.
• Flicker-reduced 50 Hz
than 1/100 s for brighter scenes.
• Flicker-reduced 60 Hz
than 1/120 s for brighter scenes.
• Manual
Exposure zone
front of an entrance door.
Note
The exposure zones are related to the original image (unrotated), and the names of the zones apply to the original image.
This means, for example, that if the video stream is rotated 90°, then the Upper zone becomes the Right zone in the
stream, and Left becomes Lower.
• Automatic: Suitable for most situations.
: Use the slider to manually set the illumination angle, for example, if the angle needs to be different
: Select the desired wavelength for the IR light.
: Turn on to let the camera use white light in night mode.
: Turn on to automatically synchronize the white light with the surrounding light.
