This document is a master document for all Allied Vision GigE camera models and is NOT camera specific
RecorderPreEventCount [Integer] R/W
Valid when AcquisitionMode = Recorder. The number of frames
returned before the AcquisitionRecord trigger event, with Acquisi-
tionFrameCount minus RecorderPreEventCount frames being
returned after the AcquisitionRecord trigger event.
SensorShutterMode [Enum] R/W
Type of the shutter.
Trigger
This group of controls relates to how an image frame is initiated or triggered.
TriggerActivation [Enum] R/W
Type of activation, for hardware triggers. This controls edge/level and polarity
sensitivities.
Range:[0–65535] Default: 0 Unit: Frames
Note

At least one image must be captured after the
AcquisitionRecord trigger event, i.e., you
cannot set RecorderPreEventCount = 1,
and AcquisitionFrameCount = 1.
Global [Default] All pixels reset and start exposure at same time.
All pixels shifted to readout at same time. All pixels have
same ExposureTimeAbs
Rolling Each row is reset, exposed, and read out in succession
from top to bottom of image. All pixels have same
ExposureTimeAbs. This mode is susceptible to motion
blur; however, this mode offers enhanced SNR/dynamic
range
GlobalReset All pixels reset and start exposure at same time. Pixels are
shifted to readout one line at a time from top to bottom of
image. This mode does not allow overlapped exposure and
readout. In this mode, ExposureTimeAbs is the time
from global reset to start of readout of top row. Subse-
quent rows will have a longer exposure time (Exposure-
TimeAbs + row readout time * row number). This mode
offers enhanced SNR/dynamic range with no motion blur,
which is useful for strobe applications
RisingEdge [Default] Rising edge trigger
FallingEdge Falling edge trigger
AnyEdge Rising or falling edge
LevelHigh Active high signal
LevelLow Active low signal
