The video works very well it is very difficult to make it operational for lack of comprehensible instruction !! The instructions were translated from Chinese with Google and this makes them very difficult to the understanding! After several attempts we got to make it work, but there are many points still éclarcir: this video camera can operate without being plugged in? what autonomy would it? how to connect with it through a computer that is not next to her? The site is in Chinese, unfortunately ... :-(
