To to the people far more well versed and educated on this stuff than I, I thank you in advance and humbly request your advice on the following applications and options for my iPad. I am a contractor by trade and will be transitioning to a completely paperless format and all contracts, estimates and other documents will be housed in the iPad or cloud for easy access and universal agreement and accessibility. I am looking for an app that allows me to wireless link my iPhone to my iPad for the following scenario: - My installers access customer roofs and we would like to real time show the customers what we are seeing (video stream) and ideally with audio. I guess we could have a quick 2-way radio in our hand but doing it over the iPad/iPhone combo would be one less device we would have to handle and be encumbered with (a definite plus while on a steep roof). I have seen this thing here (http://gizmodo.com/5511115/how-to-turn-an-iphone-into-a-wireless-ipad-camera) but it makes no mention of audio and I would therefore assume it is a "no". There is also the app store version but it appears to be still images: http://itunes.apple.com/us/app/camera-for-ipad/id366129244?mt=8 Does anyone know of a very good app that allows for this for real time video and audio? My next question would be what is the best recommended case for contractors and do they include screen protection. I have the Otterbox on my iPhone and have been pleased with its level of protection after more than a handful of drops. Thanks again and I look forward to your feedback.
