Whoever has bought it should tell the rest of us IF and HOW you set up the p2p to monitor from your phone, because in both sets I bought, there is a QR code to download the app but not the second QR code to add the device to your phone. So be careful if you want to buy it for online remote monitoring, it may not have this feature and you might end up with them being "useless" in your hands, and even worse if you have already installed them. As for the image, they are quite clear and easy to install since you just provide power and they connect wirelessly to the tablet-type screen. The lens is bad, its wide angle is small. Also, the transformer for the screen in one of the packages was burnt from the start, fortunately it's a simple 12v 3A which you can easily find and replace
