It is possible to view live or archived video recordings from the camera via the web interface. 

Viewing a stream using a self-signed certificate

When using a self-signed certificate, it is necessary to confirm its exclusion in the player to view the video stream from the camera.

1. Click the Add certificate button.
2. Accept the certificate exception.
3. Then return to the page with the player.
4. Click the Confirm button and refresh the page.

Issues and their solutions

Problem: after clicking the Add certificate button, nothing opened and an error occurred.

Solution:

1. Check the extern_host address in the configuration file /opt/evi-live/evi-live.conf;
2. The extern_host address must match the IP address of the network interface of the server where evi-live is installed. Check the client's access to the server.

Problem: after confirming the certificate, the video is not displayed.

Solution:

1. Check the availability of the camera stream via the VLC player by inserting the RTSP link into it.
2. Restart the camera. Since cameras have a limited number of connections, they may have been exhausted.
