Camera Functions
♦ Function Description
1. Auto Electronics Shutter (AES)
When using a DC Drive or Video Drive Auto Iris Lens, turn off the AES. When a Fixed Iris or Manual
Iris Lens is used, turn the AES on to adjust the shutter speed automatically.
2. Automatic Gain Control (AGC)
AGC can automatically amplify the digital signal to adjust are for the difference of light level.
3. Auto Tracking White Balance (ATW) / Auto White Balance (AWB)
When the color difference is too obvious, turn the AWB on to have better balanced color, Set the
switches to ATW to have a normal color picture.
4. Aperture Gain (APG)
APG cam make the picture becomes sharper, switch to OFF for normal mode.
5. Back Light Compensation (BLC)
When BLC is ON, the AGC, AES and IRIS operating point is determined by averaging over the
center area instead of entire field-of-view, so that a dimly-lit foreground object at center area can be
clearly distinguished from brightly-lit backgrounds. When operating the camera outdoor, turn the
BLC on to get clear picture of object on screen. For indoor using or when operating the camera in
low light environment turn, the BLC ON as well.
6. DAY & NIGH T (ICR removable)
The camera provides automatic mode changeover from color to B/W or B/W to color by sensing
different light conditions. It remains at true color mode in the day condition for optimal color and
switched to B/W mode in night condition for clear viewing by removing the Infrared Cut Filter.
7. Flickerless (FLC)
This switch captures the wide and intense range of color of some light sources and adjust the color,
gain, electronic shutter control and tracking balance to produce a good quality color picture.
8. Internal Line Lock (INT / LL)
The Line Lock is designed to stabilize the image. Always switch it on. Line Lock sync is interchange
and only available when with an AC Power source. It's unavailable with 12V DC power.
