I am just learning the ropes with my new Cuddeback Expert.....mounted it out in the back yard and got several good pics of our little Chihuahua at 45-50 ft. He isn't much bigger than a squirrel (kinda squirrely come to think of it). I have the unit mounted 3 feet up a tree trunk and it's not taking close-in pictures of the dog. I guess ifI lowered it some or tilted it down instead of horizontal it would get him close up. I had one picture with no animal in it....will a bird such as a dove set them off?
