Open Dental

Do you guys actually have good success with the chinese intraoral camaras. I bought one and the focus range is just a little too far out. It works for anterior tooth, but trying to get a nice occlusal shot of a posterior tooth requires the patients to open wider than they're able.

How does a user open up mysql administrator...is that a 3rd party program that I need to install, something found within opendental.....?
