Item Description
Fixed Shutter* Shutter Speed is a function that can adjust the duration of the electronic shutter to produce optimum image quality. Select the
shutter speed suitable for your environment.
Slow Shutter
Speed
Select the slow shutter speed suitable for your environment.
A slower shutter speed in dark conditions will help to produce a brighter image, but will produce fewer frames per second,
which may cause images to get blurry during motion.
Exposure Control This function is used to synchronize the shutter time to the fluorescent light to suppress image flickering.
Exposure Value* Drag the slider to adjust the exposure level from 0 ~ 4. The higher the value, the more light to let into the camera.
Mirror Select “ON” to rotate the images horizontally based on your installation situation when necessary.
Flip Select “ON” to rotate the image 180° when necessary.
Denoise Click and drag the slider to adjust the level to decrease the noise shown in the dark environment. The higher the value, the
higher the denoise level. 0 means off.
IR Control Select “Auto” to automatically enable IR LEDs at night or in the dark environment, “On” to always enable IR LEDs, or “OFF”
to disable this function.
IR Extend Time* Set the delay time from 1 ~ 60 in second after which the day and night switch is made, or select 0 to disable this function.
This is used for the environment where the light condition may change suddenly and usually last for a short time, for
example, the entrance of a parking lot. It may cause the day & night mode switching constantly and damage the camera.
With this function, the camera will delay the mode switch at night since the light change is temporary and unnecessary to pay
attention.
IR Turn On Level* Select the level for IR light to activate. 0 means off.
White Balance Process the current image to retain color balance over a color temperature range.
Sharpness Sharpness enhances the clarity of image detail by adjusting the aperture and sharpening the edges in the pictures.
Hold and drag the slider to adjust the level of sharpness. The higher the value, the sharper the image.
Digital WDR Digital WDR is used to simulate the effect of WDR when users need to increase image recognizability in overexposure and
dark areas. 0 means off.
