To solve this problem, you have to do the following steps:
1. Check the correctness of the URL of the RTSP stream. Usually, the URL is indicated in a camera installation manual.
Also, you can check the accuracy of the link by copying it to any player, e.g. VLC Player. If you can not see the video in a player, the URL is wrong. In another case, move to step 2.
2. Be sure that the parameters of camera settings are the following:
- codec: H.264 Main Profile;
- display resolution: 1280×720 or lower.
3. Check if the IP camera is in the same subnetwork as the indoor video entry phone (monitor).
