Review on Enhanced Security with Swann 8 Channel 4 Camera DVR Surveillance System - 4K HD, Audio, Color Night Vision, Motion Sensing, Alexa + Google Compatible by Doug Virden

Most negative reviews are unfounded. I see people commenting on non-4K videos. When you watch it on TV, the picture is very clear. The mobile app reduces the quality of what is sent to you for faster transmission. You can choose medium or high quality. The average value is set by default. If you click "High Quality", the video will be displayed in good quality. What is written to disk will be in good 4k quality. Assembly was easy, no problems. The application is good and responsive and loads instantly. All in all a very intuitive and easy setup. The app is really good too.
