This camera was purchased for usage in my front door. I work the night shift and needed a camera to keep a watch on the door and garage while I was gone. I needed a camera that runs on batteries and connects to WiFi so that I wouldn't have to make holes in the walls for electricity and Internet. I ordered this camera since it met all of my needs. Before using it for the first time, I fully charged it for a few hours. I started setting up after I was sure it was completely charged. To begin, you must first download the app and register, which takes only a few minutes. Then, once the app is ready, switch on the camera and show the QR code from your phone screen to the camera, which will immediately connect.The app itself is excellent; you can choose between HD and SD photos, as well as capture screen shots and video to save to your phone. You can enable motion detection and receive notifications when your phone detects movement. I've only had it for a few days and the battery is still charged, so I can't comment on battery life, but I'll update my review to let everyone know how long it lasts before I have to charge it again. I am extremely pleased with this small camera, and it has behaved as predicted thus far, so I give it 5 stars!
