Wireless transmission can be affected by obstacles such as walls/doors/glass, as well as other high-powered devices such as microwaves or wireless routers. We do not recommend using it upstairs or downstairs, especially if there are more than 2 doors between them. 2. If you experience audio/screen/connection problems, reset the monitor: press and hold the "RESET" button for a few seconds. Press and hold the "RESET" button on the back of the monitor at the bottom left for a few seconds. 3. There is a squealing sound when the monitor and camera are close to each other, you can lower the volume or move the monitor away from the camera.
