I bought this camera after being very dissatisfied by other brands. Here, watch in hand install in 5 minutes, ceiling mounting in 5 minutes and 10 minutes setting (only useful if you want alerts or record video when motion). The connection via smartphone is fast and fluid images (3G or 4G). No settings on this side (no open ports on the server to the required fixed ip). Everything is done in the "cloud". Night vision is very good and is greater than 5m. My living room is long and I 1OM easily distinguished the other end. The camera via the smartphone can move (small latency 2 sec at this level if via 3G). If the power cable is about 2m80 so there is no hassle to connect the camera to the mains even if you attach to the ceiling. The ethernet cable is short hand. I was planning to buy a longer ethernet cable but after wifi test was not necessary. Everything remains fluid. Last, the microphone is sensitive enough and perfectly distinguishes a conversation at the other end of the room by putting the sound of his smartphone to the max.
