I was playing with this today, it's a pretty neat little item. You download a Free App, turn it on and you can see the image on your Smartphone or Tablet. I could control the Lighting level on my Smartphone and take Pictures or Video.
I didn't give the Range a thorough test, but it worked from two rooms away, and also inside my Refrigerator from the next room. I'm thinking I'll be keeping one of these.
Bill, thanks very much. That's what I'm looking for, but I'd like to have it even simpler (I'll email rack-a-tiers). I don't anticipate using it to help snag or pull wires and the diameter is 1.25". .75" would be great. Pete
