In l ow-light conditions, AGC property can be used to improve the over all exposure as well as produce
usab l e imag e s. Under normal ligh t cond it ions t he camer a wil l di spla y a normal pict ur e . H o wever, when the
light level drops below a certain value the camera will begin o boost the signal
to compensate for the lack of light. The advantage of this technique is that your camera will produce
images in much lower light conditions. The downside
is t h at the amplification is not only on the usable
data in the image but also the background noise. This means that the more you gain up the
camera, the more noise you will see and the poorer the image quality will be.

NORMAL: Camera applies typical gain control in low light conditions showing typical detail
in darker areas at the cost of a small amount of increased noise in the overall image.
HIGH: Camera applies larger amounts of gain in low light cond itions resultin g in lots of
detail in darker areas but the image will have much higher noise in the overall image.
SHUTTER MODE
OFF:
OFF disables any slow shutter function
AUTO: The cam era us es a co mb inat ion. of applied g a in a nd s low s hu tter t o comp e nsate for
decreased light levels. If select the “SLOW SHUTTER” mode,shutter speed limit can be set.
Shutter speed limits:X2,X4,X8,X16, X32, X64 optional. The default is X2
NOTE:X2 means the shutter speed is normal divided by 2.For example: normal value of the shutter speed is
1/50,X2 will be 1/25.In low light condition,leaving the shutter open longer can optimise image, but with motion
the image can be blurred. Higher noise in gain mode,You do not suffer from blurred motion as compared to slow
shutte r mode.
