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 III dome system has 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

setting of 28 sets the AGC and slow shutter balance to favor AGC, yielding more real-time low

light images.

NOTE: The maximum slow shutter that the system will achieve is 1/2 second shutter (refer to

the

Low Light Limit

section).
