Connect an RTSP source

You can connect RTSP sources such as IP cameras to your Standalone VGA Grid over a network using the Admin panel.

RTSP video encoding is supported with H.264 video codec and MP3 or AAC audio formats.

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.
  1. Under the Source header, click Add source to open the IP sources page.
  1. Click Add RTSP source to open the source configuration page.

You can rename the source by clicking on the default source name at the top of the page ("RTSP 1" in the screenshot above). See Rename a source for more information.

  1. Under the Settings header, fill out the Source URL, Username and Password fields with information configured from your source RTSP device (see List of tested RTSP-based IP cameras for source URL syntax and credentials specific to IP cameras we at Epiphan have tested), and select either UDP or TCP from the Preferred transport dropdown menu.

    Optionally, you can also fill out the "No signal" image settings, if desired. See Add a No Signal image to a source for more information.

See Stream content using HTTP or RTSP if using another Standalone VGA Grid as an RTSP source.

  1. Click Apply to save your settings and connect your RTSP source.


Once your RTSP source is connected, you can view its basic video and audio signal information and packet loss statistics under the Status header at the top of the page. If there are any warnings or errors associated with your RTSP stream, they are also displayed here.

Alternatively, you can view stream connection information by clicking the check link under the Stream info header at the bottom of the page.
