The camera power to block na worked (green light) that qq minutes, the time that I begin to install the CD on my PC ... and funny noises in the housing = click click, light flickers, then extinguishes s ... I plug into another outlet to see, same thing, clickclick then nothing, and since n any outlet, nothing. Forced to return everything. Always easy and no pb with amazon. Refund ok. it had the air quite yet, so I have just order another one, but this time I took the wifi careful because the latter 's only wired, connect a cable with RJ45 your internet box to the camera. it seems that the wifi is unstable, that c is even recognized on the service that I had contacted for such bp of alim !! but we can put in my tjrs wired qd even if it seems bp. I'll post a comment on the other model when I have received and installed!
