It sounds like a good system if it worked. You cannot use this system or the indoor camera if you or your neighbors within 300 feet have: a wireless computer network, or a cordless phone (2.4 GHz), or a microwave that is running. I'm not kidding - I can't believe this even passed testing. I think MobiCam has a newer system that you should investigate owning. Those have lots of reviews. Pay attention to them!
