Reminder: 1.When we describe "wireless", we mean "wireless Wifi". It’s not that the camera can work without connecting to the power supply. The camera needs to be plugged in to the power supply to operate normally. 2. When the camera is turned on, it will rotate for a while and then stop. This is normal. If you need to adjust the position, you can adjust it on the APP for the best view. 3.This package does not include a TF card.It is recommended to buy a TF card for viewing and playback.If you pay to use the APP, it is not cost-effective and you need to continue to pay before you can continue to watch the replays. 4.Your evaluation is very important to us, any questions, pls contact us first.
