Black Screen

Problem: The camera channel status is normally online, but the local single-screen and multi-screen preview screens are black

Solution:

1. Confirm the device model, whether it is a video recorder that only supports H.264 encoding and connect to an H.265 camera. You can change the encoding mode of the camera to H.264 before connecting.

2. After the encoding has been modified, it still cannot be displayed. You can delete the channel and add it again or restart the video recorder to view it (the information may not be synchronized)

3. Upgrade the latest program of the device
