The + - Good image quality (HD useless to put on, it seems that the flow is better and I have not seen too much difference between my iPhone HD and not HD) - 4G connection without problem (I checked the video to a restaurant or a little anywhere, it works well) - The timeline works well. We can go back in time by clicking on the calendar. Quite nice - The sound works well in both directions so walkie talkie - Works well on PC from my desktop and iPhone I bought it to see if my dog did not put the flat bag and did not bark all day. No pb, it makes the job well Les - - I thought the install was done wirelessly. But we must connect the RJ45 on first use and create their account from a PC (not possible from the iPhone). A little walk breaks, but we do it once. I had to put 5 or 10 minutes to set up.
