It is most useful when:

• A single camera is connected (a call with 0 index is sufficient).

• The order in which the cameras are created is not important, and all camera objects must be created

(a for-loop from 0 to GetConnectedCamerasCount – 1 is sufficient).

• A search for a specific camera, following specific criteria is required (the same for-loop, this time

looking at the properties of each camera and stopping at the first that meets the criteria).

Visual Basic syntax

Dim Camera As FireiCamera

Dim i, NumOfCameras As Byte

NumOfCameras = Manager.GetConnectedCamerasCount

For i = 0 To NumOfCameras - 1

Camera = Manager.GetCameraFromIndex(i)

If Camera.Vendor = "Unibrain" Then Exit For

C# syntax

for (int i = 0; i < Manager.GetConnectedCamerasCount(); ++i)

{

Camera = Manager.GetCameraFromIndex(i);

if (Camera.Vendor == "Unibrain")

break;

}

GetCameraFromGUID method

Prototype

public FireiCamera GetCameraFromGUID(FireiGUID guid)

Comments

This method constructs a FireiCamera object and returns it, given a valid FireiGUID object. The GUID

represented by this FireiGUID must belong to a camera connected on the system; otherwise an exception

will be thrown.

It is most useful when the camera GUID is known beforehand, and provides a more direct way of accessing

the camera as opposed to GetCameraFromIndex, because the positioning of the camera on the bus is

irrelevant.

It is also mated to the SelectCamera method, as the FireiGUID returned by that method can be passed

directly in GetCameraFromGUID to create the selected camera.

Visual Basic syntax

Dim Camera As FireiCamera

Dim GUID As FireiGUID

If Manager.SelectCamera(GUID) = True Then

Camera = Manager.GetCameraFromGUID(GUID)

End If
