SHUTTER SPEED
Shutter speed is the duration of the electronic shutter. Program 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 SE Horizon 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.
NOTE: 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 the Low Light Limit section on page 31).
