I bought an endoscope some time ago, but it didn't work with any of the phones, or tablets that I have, and I found that annoying. Sure I could get out the HP lappy, but then I had to transfer files, and it was a pain in the ass. I recently saw that the
new endoscopes that come with a wifi unit work with the iPhone! So I ordered one. It showed up today.
The iPhone app is on the Appstore. There's a QR-link for it with the directions. I included the App page from the Appstore to make it easy. If you have a USB adapter you could probably plug the camera directly into an iPhone and use the free app. Haven't tested it to find out though.
It works fairly well. The camera is still low res, but that fine. It comes with some nice attachments like a hook, a magnet, and a 90° mirror. The mirror will be great for looking into the transfers.
The wifi gadget is easy to use. You do have to disconnect your phone from other wifi sources, but you can switch it back quickly enough. The phone also remembers the 8 digit password so you only have to enter it the first time. Photos show up in the Photo app, and on your Mac just as if you had employed the built in camera—which is totally great!
While this is "Chinese" brand it shipped from SoCal, was here in about three days, and cost just a little over $25.
