Exposure
Exposure mode: 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.
• 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: Use exposure zones to optimize the exposure in a selected part of the scene, for example, the area in 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.
• Center: Uses a fixed area in the center of the image to calculate the exposure. The area has a fixed size and
position in the live view.
• Full
• Upper
• Lower
• Left
• Right
• Spot: Uses an area with a fixed size and position in the live view to calculate the exposure.
• Custom: Uses an area in the live view to calculate the exposure. You can adjust the size and position of the area.
Max shutter: Select the shutter speed to provide the best image. Low shutter speeds (longer exposure) might cause motion blur
when there is movement, and a too high shutter speed might affect the image quality. Max shutter works with max gain to
improve the image.
Max gain: Select the suitable max gain. If you increase the max gain, it improves the visible level of detail in dark images, but
also increases the noise level. More noise can also result in increased use of bandwidth and storage. If you set the max gain

: The aperture, gain and shutter are fixed.
: Uses the entire live view to calculate the exposure.
: Uses an area with a fixed size and position in the upper part of the image to calculate the exposure.
: Uses an area with a fixed size and position in the lower part of the image to calculate the exposure.
: Uses an area with a fixed size and position in the left part of the image to calculate the exposure.
: Uses an area with a fixed size and position in the right part of the image to calculate the exposure.
