Hi Dave
It's just a cheap endoscope from
Amazon that doesn't have a brand name or model. It comes with a 15m cable and a minidisk with a bunch of drivers on it (I assume) but the iPad doesn't have a disk drive so I won't know exactly whats on it until I get home and check it out on the iMac. If you look on youtube you'll see a video of the exact same camera attached to a bunch of drain rods that a guy is using on his MacBook. I think its entitled "make yourself a cheap drain camera" (9:41 duration).
Yes its a lightning adapter.
The guy says he's using a free app but I can't make out the name: It sounds like he's saying "quik-ear" or "quickier" or something like that.
As for me I have a 12gig iPad ver 8.2 (12D508)
