) As List(Of ICameraInfo)

Parameters#

 

deviceType
Type: System.String
The name of the device type to enumerate connected devices. The static class DeviceType can be used to get a list of valid device class names.

Return Value#

Type: List(ICameraInfo)
Returns a list of ICameraInfo objects, one per camera found. The list is ordered by serial number

Remarks#

The function queries for camera devices of a specific device class connected to the system and returns a list of ICameraInfo objects describing the cameras. The returned information can be used to create a specific Camera object. The static class DeviceType can be used to get a list of valid device type names.

Thread Safety: This method is thread-safe.
