Connect an RTSP source
Decoding a 1080p RTSP signal at 30 fps consumes approximately 10% of your Standalone
VGA Grid's CPU power. If an RTSP source is connected but unused in any channel,
Standalone VGA Grid decodes only key frames to preserve CPU resources.
To synchronize timestamps between your RTSP source and your Standalone VGA Grid, the same time
synchronization server should be used for both devices. It is recommended that you configure an NTP server
on your Standalone VGA Grid and use Standalone VGA Grid as a time synchronization server for your RTSP
source. See Configure synchronized time (NTP, PTP v1 and RDATE).
Due to the nature of external encoding devices such as RTSP sources, it is possible for the timestamps
between your Standalone VGA Grid and your RTSP source to gradually become out of sync. If there is a 2500
–3000 ms timestamp difference between your RTSP source and your Standalone VGA Grid, then a "no signal"
image will display and your RTSP source will not stream any audio. Re-connecting your RTSP source resets any
time synchronization issues.
To connect an RTSP source to your Standalone VGA Grid:
1. Login to the Admin panel as admin. See Connect to the Admin panel.
2. Under the Source header, click Add source to open the IP sources page.
3. Click Add RTSP source to open the source configuration page.
