Pearl-2 User Guide Supported web cameras
Supported web cameras
Pearl-2 supports most webcams and USB audio sources, such as USB microphones. The following list of web
cameras have been tested for compatibility with Pearl-2. If your web camera doesn't appear in the list, that
just means your model hasn't been tested. It's likely that it will work without any issues.
Table 50 List of tested Web cameras
l Logitech HD Pro Webcam C920 (Max video mode: 1920x1080@30)
l Logitech C925e (Max video mode: 1920x1080@30)
l Microsoft LifeCam Studio (Max video mode: 1280x720@30)
l Microsoft LifeCam HD-3000 (Max video mode: 1280x720@30)
l IPEVO Ziggi-HD Plus
For the Ziggi-HD Plus web camera, enable the power line frequency setting in the web camera
before connecting the camera to Pearl-2.
When you Configure a video input source, the Default video mode is not necessarily achievable for that
web camera. For instance, a camera might have a default mode of 1080p but have a Maximum video mode
of 720p. If no settings are changed, the camera simply outputs video at 720p in this case.
Connect an RTSP source
You can connect RTSP sources such as IP cameras and other Pearl-2 systems to your Pearl-2 over a network
using the Admin panel. For a list of tested cameras and their URL syntax, see Tested RTSP-based IP cameras.
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 Pearl-2's
CPU power. If an RTSP source is connected but unused in any channel, Pearl-2 decodes
only key frames to preserve CPU resources.
To synchronize timestamps between your RTSP source and your Pearl-2, the same time synchronization
server should be used for both devices. We recommend that you configure an NTP server on your Pearl-2 and
use Pearl-2 as a time synchronization server for your RTSP source. See Configure a time server.
The timestamps of an RTSP source and Pearl-2 tend to gradually go out of sync. If there's a 2500 –3000 ms
difference between the timestamp of your RTSP source and Pearl-2, a "no signal" image displays and your
RTSP source won't stream audio. Re-connect your RTSP source to reset any time synchronization issues.
