SHUTTER SPEED
Shutter speed is the duration of the electronic shutter. You can configure the shutter speed to operate automatically (Auto) or manually (Numeric Value).
AUTO (default): The electronic shutter speed is set automatically by the amount of light sensed by the camera.
NUMERIC VALUE: Spectra IV dome systems have several numerical shutter speed settings. The higher the number, the faster the electronic shutter.
The slowest shutter speed setting is 2 = 1/2 second.
The fastest setting is 30,000 = 1/30,000 second.
Increasing the shutter speed lowers the light sensitivity and reduces the streaking of fast moving objects.
Set the shutter speed to 100 if you are using an NTSC camera in a 50 Hz environment. This will eliminate any flicker that may occur in the picture.
AGC LIMIT
AGC limit allows users to adjust how the system balances AGC (automatic gain control) and electronic shutter in low light conditions. As scene lighting decreases, the system will automatically adjust, adding a mixture of AGC and slow shutter according to the AGC limit setting. AGC limit can be set between 0 and 40, with 40 applying maximum AGC before slow shutter. In contrast, setting AGC limit to 0 will force the system software to apply maximum slow shutter (as defined by the low light limit setting) before any AGC is applied. The default AGC settings vary depending on camera model.
NOTE: The maximum slow shutter that the system will achieve is 1/2 second shutter (refer to Low Light Limit on page 24).
AUTO IRIS
Auto iris is the lens function that automatically opens and closes the iris in response to changing light conditions.
You can configure the auto iris to operate automatically or at a
OFF: Auto iris is disabled, and control is always manual.
AUTO (default): The iris is adjusted automatically to produce a constant video output as determined by the auto iris level setting.
If auto iris is in the auto mode, it will remain that way until the iris is manually opened or closed. The dome will return to auto mode when it is panned or tilted more than 15 degrees.
Auto Iris Level
Auto iris level is the numeric value the auto iris uses to maintain the brightness level of the camera. Increase the value to brighten the scene. Decrease the value to darken the scene. This setting can be adjusted if the video level in the auto iris mode is too bright or too dark.
NOTE: If backlight compensation is ON, decrease the auto iris level setting.
*This setting applies to Pressurized Spectra IV dome systems only.
