ACUIX PTZ Dome: 35× Camera Blocks
It is not recommended you operate the 35× camera block in full manual mode.
For this reason, the ACUIX has four manual exposure modes available with the
35× camera block:
Shutter Priority
In this mode the shutter time is manually controlled but the video gain and lens
iris remain in auto mode. This mode controls the amount of blur due to the
motion of moving objects.
Iris Priority
In this mode the lens iris is manually controlled but the shutter time and video
gain remain in auto mode. This mode controls the focus depth of field—wider
apertures (smaller f-numbers) result in a narrower depth of field.
Gain Priority
In this mode the video gain is manually controlled but the shutter time and lens
iris remain in auto mode. This mode controls the amount of video noise in the
picture—a higher gain results in higher video noise.
Full Manual
This mode operates the same as the manual exposure mode of the 18× and
26× cameras as described above.
Note The light level values below are only approximate numbers. The
actual values in a specific application depend on the spectrum of the
light reflected from or emitted by the scene. Light measurements in
lux do not include the infrared (IR) content of the light.
