The following functions are only implemented when Auto Exposure is
enabled.
•
Brightness
- The higher the number, the brighter the picture. This
is the target for the auto exposure code.
•
Sync
- Fluorescent lighting refreshes at 60Hz or 50Hz, depending
on what country you live in. This may interfere with the camera’s
exposure. Set the sync to the appropriate value for your area
(example: U.S. is 60Hz). If you are pointing the camera outdoors or
do not use fluorescent lighting, turn this option off.
Manual Exposure
Enabling Manual Exposure causes the camera to expose images at
the value placed in the Exposure field. Keep in mind that using manual
exposure is not advised for outdoor imaging, since the light conditions are
constantly changing. You may opt to use manual exposure indoors if your
lighting conditions do not change. Here are some sample values and their
fractional and decimal equivalents:
48 = 1/1000 second (0.0001)
96 = 1/500 second (0.002)
248 = 1/200 second (0.005)
480 = 1/100 second (0.01)
800 = 1/60 second (0.1666)
960 = 1/50 second (0.020)
1600 = 1/30 second (0.0333)
3200 = 1/15 second (0.0666)*
6000 = 1/8 second (0.125)*
12000 = 1/4 second (0.25)*
24000 = 1/2 second (0.5)*
32767 = 0.68 seconds (maximum exposure)*
* may introduce pixel noise
EXPOSURE GRID
When Auto Exposure is enabled, NetCam SC adjusts the exposure
of the image based on the average brightness of the pixels located in
the selected regions in the Exposure Grid. If you want the camera to
determine the exposure based on only the sky, you would select the
squares that apply to the sky (click the View Grid button to see the grid
over the image). Conversely, if you’d like the exposure to be determined
by the foreground, select only those squares. This is comparable to the
spot exposure on a traditional camera.

Auto Iris
- Only enable this option if a DC Auto Iris lens is
connected into the camera. If your camera does have a DC Auto
Iris lens connected, you may optionally enable this option when the
