Sound doesn't work on iPhone – FLIR FX Review

Update 1/13/16: sound still doesn't work on iPhone app. Camera stopped working and it took weeks to discover that I needed to update the firmware in order to get it working again. I also had to unplug the camera a few times before it would work, which was frustrating since the camera is in a different state with someone who isn't tech savvy. Original review: Sound doesn't work live on iPhone (5s or 6s) but works fine on iPad. Image quality and video playback (sounds works when playing videos but not live) are great. Camera are app are easy to setup and use.
