16 TruVision Analog PTZ Camera Configuration Manual
• Manual: Manually define the iris value, gain value, and shutter speed
depending on the lighting conditions.
Iris value
The IRIS value measures the amount of light entering to the lens. You can set the iris value
from 0 to 17 in response to the changing light conditions.
Note: The iris is fully closed at value 0 and fully open at value 17.
Shutter speed
The speed of the electronic shutter controls the amount of light entering to the lens in a unit
of time (a second). You can manually configure the shutter speed for the PTZ camera, and
you can also enable the slow shutter function for low lighting circumstances.
1. Shutter speed. If you set the SHUTTER value to a higher value (shutter speed is
faster), the amount of light entering per second is reduced and the image becomes
darker. Select one of these values: 1, 2, 4, 8, 15, 30, 50, 125, 180, 250, 500, 1000,
2000, 4000 or 10000.
Note: The value of X indicates that the shutter speed is 1/X second.
2. Slow shutter. Set the SLOW SHUTTER value between 0 and 5. The shutter speed can
automatically slow down to extend exposure time under low lighting circumstances to
obtain clearer image.
Note: Turn on INITIALIZE LENS to trigger an automatic lens initiation and ensure
normal operation.
Gain value
• Gain value: This indicates the amplification degree of the original image signal. You can
set the value between 0 and 15.
• Gain limit: The higher gain value set, the more noise appears in the image. Set the
maximum user configurable gain value between 0 and 15 to limit the gain range and
control noise in the image.
Exposure compensation function
Set the EXPOSURE COMP value between 0 and 14. The default value is 7.
White balance
You can set WHITE BALANCE mode as AUTO, INDOOR, OUTDOOR, CUSTOM (user
defined), ATW (auto-tracking), or SEMI-AUTO (Semi-auto).
Note: In CUSTOM. mode you need to define the value of RED and BLUE.
Image flip
If you enable the IMAGE FLIP function, the image is flipped diagonally along its central
axis, seen as a mirror reflection of the image.
