This surveillance camera can be connected to the WLAN network. It has a two-way audio system so you can talk to the other person. The sound quality is okay. The camera has infrared night vision and delivers a very good black and white picture on the phone. In daylight you get a sharp and high-contrast color image. The surveillance camera is also Alexa-compatible, but I hadn't been able to establish a connection and actually don't need it. The camera also has motion detection and can then send a message to the recipient. You can use the camera with an SD card up to a maximum of 120 GB, this is unfortunately not included in the scope of delivery. After installing the app, for which you unfortunately have to register again, you can also rent cloud storage for a fee (the first six months are free). This means you can keep an eye on everything at home, even when you're on the go, no matter where you are in the world. The camera can rotate 120° vertically and 355° horizontally. This can all be controlled via the app. That worked fine right away. I would recommend this camera, it was fairly easy to set up and the images are of excellent quality. So I'm happy to give it five stars and a buy recommendation.
