I'm looking for a little help. I had a problem recently, where it would have been helpful to "see within" the wall (from above). I need a "snake" camera with a light, that would allow me to clearly see about 8 or 9 feet that I can connect to my Andriod phone. Most of what I've seen is cheap crap, has a display, or has a short focal length. I thought finding this would be a no-brainer. I guess that's what I get for thinking. Thanks, Pete
