Checking if any AV devices are connected

I have this code which assumes that an AV decide is connected...

AVCaptureDeviceInput *device_input = [[AVCaptureDeviceInput alloc] initWithDevice :
                                              [AVCaptureDevice devicesWithMediaType : AVMediaTypeVideo][0] error : nil];

How can I modify that code so that I get a message like this...

if (No AV devices were detected)
NSLog(@"No AV devices were detected");
else
NSLog(@"The following devices were detected...");

Thanks, Len.

If you have to check for audio device you can use below code- 

-(void)checkForDevice{
    AVCaptureDevice *audioDevice = [[AVCaptureDevice devicesWithMediaType:AVMediaTypeAudio] firstObject];
    AVCaptureDeviceInput *audioDeviceInput = [AVCaptureDeviceInput deviceInputWithDevice:audioDevice error:&error];

     if (error)
     {
        NSLog(@"%@", error); //problem with the device
     }
     else
     {
         //device is available  
     }
}

In the similar way you can check for vedio and other AV Devices.
