Camera Setting
A few camera parameters can be configured for improving image quality according to the recording
environment.
Setting Description Default
Electronic Shutter Set the electric shutter to Auto or Fixed.
Auto sets the camera to use AES (Automatic Electronic
Shutter). The camera will adjust shutter speed to respond to
keep signal output at optimum level relative to available light.
AES changes the iris level automatically without using the auto
iris lens.
Fixed: means ALC (Automatic Light Control). Shutter speed
will be fixed, while the iris automatically adjusts to lighting
conditions.
Auto
Auto Gain Control
(AGC)
The AGC function provides clearer images in low light
conditions by using an amplifier to boost video signals when
light is dim, effectively increasing camera sensitivity. In some
bright environments, the amplifier may be overloaded and may
distort the video signal. Thus, it is necessary to monitor signal
levels relative to AGC control circuits and, when overloaded,
switch off AGC.
On
White Balance White balance is a basic form of color balance. It sets for the
camera a “true white” referent, telling the camera what the
color white should look like so it may record it correctly. Since
white light is the sum of all other colors, the camera will then
display all colors correctly.
To set “White balance” in the VPort 16 camera:
Step 1:
Aim the camera lens at a well-lit patch of white in the local
environment.
Step 2:
