AVT GigE camera attributes

AVT GigE Camera and Driver Attributes V1.3.1

This document is a master document for all AVT GigE camera models and is NOT camera specific

AcquisitionMode – Enum – R/W

Determine how many frame triggers the camera receives after acquisition start

event.

AcquisitionStart – Command

Software command to start camera receiving frame triggers. Valid when

AcqStartTriggerMode = disabled. See FrameStartTriggerMode.

AcquisitionStop – Command

Software command to stop camera from receiving frame triggers. Valid when

AcqEndTriggerMode = disabled. See FrameStartTriggerMode.

RecorderPreEventCount – Uint32 – R/W

The number of images returned before the AcqRec trigger event, with Aquisi-

tionFrameCount minus RecorderPreEventCount images being returned after

the trigger event. Valid only when AcquisitionMode = Recorder.

Continuous [Default] The camera will continuously receive frame triggers

SingleFrame The camera will only receive a single frame trigger event. Fur-

ther frame triggers will be ignored until acquisition is stopped

and restarted

MultiFrame The camera will receive AcquisitionFrameCount number of

frame triggers. Further frame triggers will be ignored until

acquisition is stopped and restarted

Recorder The camera will continuously capture images into camera

memory, but will not send them to the host until an AcqRec

trigger signal is received. Further, AcqRec trigger events will

be ignored until acquisition is stopped and restarted.

This feature allows returning RecorderPreEventCount number

of frames before the trigger event, and AcquisitionFrame-

Count minus RecorderPreEventCount frames after the trigger.

When AcqRec trigger is received, the currently imaging/

acquiring image will complete as normal, and then at least

one more image will be taken. Camera memory is a circular

buffer, once it is full, it starts overwriting images

Range: [0– 65535] Default: 0 Units: Frames

Note



At least one image must be captured after the AcqRec trigger

event. That is, you cannot set RecorderPreEventCount = 1,

AcquisitionFrameCount = 1.
