This here sets the near and far distance that your camera is able to see. Be careful though, the more you can see in frame = lower FPS. There are two usages, one is for setting the range for a specific camera. The other is for just one.
dbSetCameraRange ( float fNear, float fFar ); // Specific camera
dbSetCameraRange ( int iCamera, float fNear, float fFar ); // Single undefined camera
I found this right in the docs, there are also many threads about this. If you use the search, you could save a lot of time waiting for a response. If all else fails, try experimenting.
