I should have read in detail the presentation on the amazon web. Extract: "High Degree of integration without bounded DDNS, auto finding and modification, easier operating CMS" sic! Low Doc (3 pages A6) in English (or Chinese!), The rest in English on the CD, so not in the rules of French law ... Failed to activate Wifi on the one I received. So use only by Ethernet. And only on the local network, because do not count on the doc to tell you what to do to your router so that it is visible from the web as stated on the advertising. So a single star for use in local and cable, but no more. I do not recommend this purchase I returned (and back will cost me 1.99 although it does not work for wifi) and will (perhaps) try a more expensive model, but I hope more functional!
