How can we know is Camera available or not in iPad

I am implementing an iPad application, and I need to get pictures from the library and camera as well. My problem is the first version of iPad doesn't have the camera in built. How can I determine if camera is available or not? Can you guys please help me on this.

Thanks in advance, Cha开发者_运维知识库ndra.

This looks like a good start: [UIImagePickerController isCameraDeviceAvailable]
