I bought one for testing and two others to complete my setup in my house. Pretty, well finished, light and quite discreet, it works very well in remote communication with a dynamic DNS account. I can look in my house when I want with my smartphone and the picture quality is excellent (note the lens adjustment is very sensitive: a degree too and it is not clear). The only concern is the motion detection. It can quickly become fair warning emails. We must firstly that the room where the camera does not have a window letting in external brightness variations (you must shut the blinds and / or curtains). It will make dark but the integrated infrared lighting sufficient for a room of 30 m². Finally, I recommend this camera to record on NAS to the lifting of doubt, but it does not replace a real alarm system with infrared detectors.
