frames captured during the acquisition and the way the acquisition stops. It can take any of the values
shown in Table 30.
Value
Description

Frames are captured continuously until stopped by the
AcquisitionStop command
SingleFrame
The camera captures only one frame and stops the
acquisition
MultiFrame
The camera captures a specific number of frames set by the
AcquisitionFrameCount property and stops the acquisition
Table 30: AcquisitionMode values
5.4.1.2
Acquisition Frame Rate
The
AcquisitionFrameRate
property is a feature which limits the frequency at which images are captured
by the camera. Using the
AcquisitionFrameRate
feature it is possible to decrease the number of frames the
camera acquires and transmits in free run mode, which consequently lowers the bandwidth required by the
camera.
This feature is useful in situations where the link bandwidth is limited, like in applications where several
GigE Vision cameras stream images to PC via switch and there is single Gigabit Ethernet link connecting
switch and NIC on PC.
Setting the
AcquisitionFrameRate
property to zero effectively disables the feature, allowing the camera to
acquire and transfer images at maximum frame rate.
5.4.2
Trigger Features
The
Trigger Features
chapter describes features related to synchronizing the camera with an external device
or software application.
5.4.2.1
Trigger Selector
The
TriggerSelector
property provides access to the properties of different triggers supported by the
camera, as shown in Table 31.
