reproduction, sharp and stable picture.
2 Features
1. Color & B/W mode: Daytime color and user selectable color or b/w
mode when under low lux condition.
2. Resolution: 420/520 TV lines of horizontal resolution.
3. Low lux: BY employing high sensitivity image sensor and low noise
circuit design produces 0.5 lux and signal-to-noise ratio of 48 dB.
4. White Balance: The wide range of Auto Wide balance(AWB) and Auto
Tracing White balance (ATW) allow the camera to adjust automatically
the tone according to the color temperature of the light source
illuminating the subject.
5. Back Light Compensation: Smart digital control Auto BLC, ensure for
use against any unusual lighting conditions.
6. Auto Exposure System: Advanced Auto Exposure System for both fix

4.1 AE setting
In different situation, there are two options for shutter mode, they are AES
mode and ME mode.
4.1.1 AES mode
4.1.1.1 If you use a fixed or manual iris lens, please select the AE mode to
control the exposure with electronic shutter, the range of shutter speed is from
1/60(1/50) sec to 1/100,000 sec
As you take a picture with strong light behind the subject, the subject only
a slight darker luminance than the overall screen, please set BLC ”on” to
perform through exposure compensation operation by apply the appropriate
luminance intensity to the dark areas.
In normal light condition, please set the DIP SW to BLC “off”.

4.1.1.3 In flicker less mode, the shutter speed is fixed to 1/100 sec for NTSC
system and 1/120 sec for PAL system to reduce the flicker of fluorescent lights.
This is better for the Japanese market.
Note: When using manual iris lens in flicker less mode, please select table “a”
and “b”. If you are using auto iris lens in flicker less mode, please select table “c”
and “d”.

4.2 AGC mode
Set the DIP switch to SUPAGC, the gain is up to 34 dB. In normal AGC the
gain is at 28dB

4.3 ATW mode/AWB mode
4.3.1 ATW mode --Set the DIP SW to ATW position, the color temperature is
monitoring continuous and the white balance is set automatically by internal
microcontroller, the operating color temperature range is from 2500°k to
18000°k.
4.3.2 AWB mode-- Conventional auto white balance, set the DIP SW to AWB
position. In this case, operation is performed at a faster operating speed than
ATW mode.
4.4 Line-lock mode
Set the vertical phase of the camera video signal to match the phase of AC
power source to avoid color rolling.
When using dual power source model, when set the DIP SW to L.L, the
camera will automatically detect and adjust to L.L mode for AC power source,
and INT for DC power source.
4.5 Low lux with Color mode and B/W mode
Set the DIP SW L. LUX. COLOR or L.LUX B/W to select the picture when
under low lux condition, with advanced technology built-in, it is optional to
select low lux color mode and low lux B/W mode with this camera.
Suggest setting the DIP SW to SuperAGC when in a low lux B/W mode.

5 Infra-Red Illuminator
When under low light environment, the normal color camera cannot obtain a
clear picture with IR illuminator, this camera has been specially designed with
the capability to accept most IR illuminator to have a clear and contrast B/W
picture when in a completely dark area.
The range of Infrared wavelength is from 830nm to 1000nm.
The focus may slightly vary with IR wavelength due to lens diffraction to
long-wave, while installing the camera with IR illuminator, please check the
focus under IR illumination and normal lighting condition, and find a adequate
focusing position.
