This wireless security camera is amazing. The quality of the camera is unexpected, the video is very clear and can be played back. With the automatic smart night vision function, it automatically switches from day mode to night mode, even in the dark night, it can clearly see the monitoring. I tried the motion detection and alarm function, and this small camera can not only report the video, but also immediately send an alarm notification to my mobile phone. These features are very good and meet all my requirements. I am very satisfied with my purchase.
