Connect an RTSP source
Decoding a 1080p RTSP signal at 30 fps consumes approximately 10% of your VGADVI
Recorder Pro's CPU power. If an RTSP source is connected but unused in any channel,
VGADVI Recorder Pro decodes only key frames to preserve CPU resources.
To synchronize timestamps between your RTSP source and your VGADVI Recorder Pro, the same time
synchronization server should be used for both devices. It is recommended that you configure an NTP server
on your VGADVI Recorder Pro and use VGADVI Recorder Pro 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 VGADVI Recorder Pro 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 VGADVI Recorder Pro, 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 VGADVI Recorder Pro:
1. Login to the Admin panel as
admin
.
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.
