I have the same problem. If this is the case, I'll be returning my 5222L. Do you know if the DCS-2132L has a two way audio feature? meaning, you can talk to the iphone and be heard from the camera.
This is false advertising, this video says you can - http://www.youtube.com/watch?v=xFdP-kj2EYs
The reason why I bought this model is because I thought you can talk from your iphone and be heard from the other end where the camera is.
