The app is easy to use & set up. These are very easy to set up. I have two that I use in my home. It takes 5 minutes to set up, and it gives what appears to be clear picture, on a cell phone, however, on my iPad, it's a very grainy depiction.
The sound is very clear, when you want to listen to the sound in the room. However, when you talk, it's a very quiet sound. My dogs don't quite hear me.
I have tried and compared these to the Belkin IP Night Vision Cameras, and I think this one ranks higher, because you can actually move this camera around.
