Problem:
What is DCAM/IIDC?

Solution:
DCAM (1394-based Digital Camera Specification) is a digital camera interface standard that defines the protocol for exchanging video data with IEEE 1394 cameras. This standard was initiated by IIDC (Instrumentation & Industrial Digital Camera) of the 1394 Trade Association. It describes the sending of uncompressed video streams on the asynchronous channel of the IEEE 1394 bus. Audio data transmission is not taken care of by this standard. DCAM also enables the user to modify parameters of the camera, such as brightness and shutter settings, in software.

Firewire cameras must be compliant with the DCAM specification to work with the NI-IMAQ for IEEE 1394 and NI-IMAQdx drivers. It is important to note that not all firewire cameras are DCAM cameras.

For more detailed information on DCAM, please refer to the ‘DCAM Specification for Firewire Cameras’ section of the following document : Developer Zone Tutorial: Acquiring from Firewire Cameras with National Instruments NI-IMAQdx and Legacy NI-IMAQ for IEEE 1394.
