It's a Bluetooth connection, so is wireless, if you have a bluetooth enabled computer. It zooms to x4, picture still pretty clear, even in very dim light. The lens unit is one piece so I doubt you could buy a pre-made macro lens. However on 'another' website in the photo forum there is a guy in India who describes various lenses he has jury-rigged from binoculars and such. You seem like the kind of guy who could get into that!
