A good product that can take photos remotely, and view live on the smartphone that sees the camera with android application, the wifi is not very powerful, + - 8m max. Personally I do not think a price higher than that offered by Amazon is justified, the wifi deserves a little short at least be integrated into all new Nikon cameras only voila, 10 euros here and 40 euros there, and another 60 euros there, is the political "Please send the monarchy" Poor us !!!
