Software Requirements

External SoftwareNone Required (Plug-and-Play)
ProtocolUVC (USB Video Class) Compliant
Windows SupportNative Support - No drivers needed
macOS SupportNative Support - No drivers needed
Linux SupportNative Support - V4L2 compatible
Zero Software Required Because it is fully UVC compliant, it requires absolutely no proprietary drivers, external software, or libraries for retrieving images.While we provide helpful optional utilities like our Camera Tester and dweOS, these are strictly optional. You can plug the camera into your system and immediately view the feed using standard built-in camera applications (like Windows Camera, OBS, etc).

Bitrate Control Library

For specific advanced application using H.264 mode, you can manage the camera’s bitrate via our open-sourced bitrate control code.
