GigE Camera and Drivers Features V3.0.0

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

StreamHoldCapacity [Integer] R

The maximum number of images (for the current size and format), which can be

stored on the camera when StreamHold is enabled. Used in Acquisi-

tionMode = Recorder, or StreamHoldEnable = On. This value is dif-

ferent for each camera depending on the camera internal memory size and the

ImageSize.

StreamHoldEnable [Enum] R/W

Control on-camera image storage; this control is like a “pause” button for the

image stream.

Timestamp

Allied Vision GigE cameras have a very accurate timestamp function for time-

stamping images.

GevTimestampControlLatch [Command]

Captures timestamp and stores in GevTimestampValue.

GevTimestampControlReset [Command]

Resets the camera’s timestamp to 0. Not possible while PTP enabled (PtpMode

= Master, or Auto).

GevTimestampTickFrequency [Integer] R

Frequency of image timestamp. The image timestamp can be useful for deter-

mining whether images are missing from a sequence due to missing trigger

events. Cameras offering clock synchronization via PTP will have a GevTime-

StampTickFrequency of 1,000,000,000.

GevTimestampValue [Integer] R

Value of timestamp, when latched by GevTimestampControlLatch.

Unit: Frames

On Images remain stored on the camera, and

are not transmitted to the host

Off [Default] The image stream resumes, and

any stored images are sent to the host

Note



Use PTP for synchronizing cameras.
