Note:
Manual control allows you to adjust iris size from complete closed
(“0”) to fully open (“100”). If you set iris to “manual”, then shutter takes
over the priority position for exposure control (seeing “ESC” on shutter
setting).
Shutter:
Shutter is the “pseudo” mechanism for controlling light energy by varying
CCD exposure time. For normal indoor use, shutter speed is usually set
to 1/60 sec (1/50 for PAL). In stronger light condition, shutter speed must
be reduced, or image could be too bright. For darker scene, shutter
should be increased. This camera offers 3 options to you:
ESC (Auto): If iris is set to “manual” mode, ESC is the choice used for
the most conditions. Software will check light level and set up shutter
speed automatically.
Manual: To assign a fixed shutter speed. This can be the choice if
camera stays indoor with constantly stable ambient light.
In normal light, try speed between 1/60 --- 1/500. Be advised that, for
speed higher than 1/120, color rolling can be easily observed.
In faint or dark, use extended exposure (x2, x4, ---); Try the low number
first. If picture is still dark and with much noise, try the higher times.
Extreme high (1/2000 and above) and sens-up exposure (x64, x128) are
not recommended unless in extreme condition.
Anti-Flicker: Automatically set the shutter speed to 1/50 (1/60 for PAL
system) to avoid the flicker created by the normal lighting system
(especially in the fluorescent light environment).
AGC:
Auto-Gain-Control, for keeping video output level stable and stays within
standard range. Turn AGC to high in dark, or low in strong light
condition.
Note:
If you turn the AGC off, then SNR and sens-up functions will be
defeated automatically. (See “Exposure Setting Combination” table on
following page)
SSNR:
Super Noise Reduction, for improving quality of the video captured in
dark. OFF, Low, Mid and High are the options.
When camera works in dark and video gets weak, a lot of noise
(snow-like spots) will be observed on image and recorded. Such noise
will down grade the quality and performance of the entire security
system, live view and recorder (DVR), significantly.
SNR function is to reduce the noise level when video level is low due to
