CAME-TV Crystal-800: http://cheesycam.tv/Crystal800
A peek at a prototype version of the CAME-TV Crystal-800 Wireless Video Kit. It works like any standard video kit, transmitting long range. But a huge feature here is that the Receiver also creates it's own WiFi SSID that you can connect to from an iOS Device. With an APP on your iPhone, iPod Touch, or iPad you can then get access to the live feed turning your iOS device into a wireless monitor!
With this prototype, the iOS APP does not offer anything like focus peaking, false color, or histograms, but I think that can be done by updating the APP (let's hope they add that feature).
