Got a couple of these now as i was very impressed with it first time i bought it, comes very neatly packaged (no wasted space) with everything you need to not far off plug and play once you've connected to your wifi network. Download the app onto your smartphone from the QR code in the instructions log in and off you go, you can also download the app onto however many devices you wish and share the camera with them so all can view. Picture is very good as is the audio and once you've got a micro sd card in it all features are available for use (i would recommend 64gb which is the max it supports for longer recording time although it does loop). Night vision, 2 way audio, motion detection and alert to your phone. Upon motion detection captures a still shot and if set will sound an alarm from the camera (handy to make any intruder uneasy) and of course there is the useful aspect of using it as a baby monitor or also in our case a pet monitor
