Exposure Time
It refers to the time to press the shutter. Increasing the exposure time can
increase the signal-to-noise ratio and make the image clear. The longer the
time, the more the sum of photons to the CCD\CMOS surface, the brighter
the captured image will be, but if it is overexposed, the photo will be too
bright and lose the image details; if it is underexposed, the photo will be too
dark.
Exposure Gain
It refers to the amplification gain of the analog signal after double sampling,
but the noise signal is also amplified in the process of amplifying the image
signal. The gain is generally only used when the signal is weak, but you do
not want to increase the exposure time.
Contrast Mode
Auto mode
：
The camera automatically sets the contrast according to the
environment, no need for the operator to adjust
Manual mode
：
Manually set the camera's contrast parameters.
Contrast
Contrast refers to the contrast between light and dark in the picture. Increase
the contrast, the brighter areas will be brighter and the darker areas will be
darker, and the contrast between light and dark will increase.
Saturation Mode
Auto mode
：
The camera automatically sets the saturation according to the
environment, without the need for the operator to adjust
Manual mode
：
Manually set the camera's saturation parameters.
Saturation
Saturation refers to the color. Adjusting the saturation will change the color.
The greater the adjustment, the more distorted the image color. Adjusting the
saturation is only suitable for pictures with insufficient colors. When the
saturation is adjusted to the lowest, the image will lose its color and become
a black and white image.
Sharpness Mode
Auto mode
：
The camera automatically sets the sharpness according to the
environment, no need for the operator to adjust
Manual mode
：
Manually set the sharpness parameters of the camera
Sharpness
Sharpness is sometimes called "sharpness", which is an indicator that
reflects the sharpness of the image plane and the sharpness of the edges of
the image. If you increase the sharpness, the contrast of the details on the
image plane is also higher and it looks clearer.
Enable Onvif
Enable or disable the onvif protocol, after enabling it, the device can be
discovered through a recorder that supports ONVIF
