Read these reviews. This thing is a joke. Im sitting here at 4 AM awake and frustrated because the app wont stream video any longer. This monitor was my back up plan and the video I have been using to see my child while traveling. Our main monitor failed earlier this week and while waiting for a warranty replacement, Ive tried using this. Absolute junk, the software to support this hardware. Again, read the comments on here. Even with that limited purpose, if two devices have the app open in iOS (not even active) and they have not completely killed the app in their "active apps", a third device cant get in. Seriously, the product (the camera) is OK (quality video and audio) but the whole app (and the website for computers) is terrible. Apple, you need to quit selling this product. This does not work anything close to as advertised.
Again, Do Not Plan To Use This As A Baby Monitor, I implore you. You will be frustrated, disappointed and, quite likely, very angry. I know I am.
