The image is not 4K but it looks quite good. From your mobile, you can connect to watch live video and move the camera and microphone. It has an audio transmitter and receiver. The antennas when opening the back cover are not functional, but the connection is smooth and I don't experience any interruptions. For recording, you have two options: use an SD card or pay monthly to upload to the cloud. In general, quality and price are very satisfactory with what they offer. 100% recommended for homes, but I would look for something better for businesses.
