Orchid Core VMS supports operation in WebRTC mode and the original Low-bandwidth mode. The benefit of WebRTC mode is that it allows for viewing full-bandwidth, live and recorded video streams through a web browser without requiring a plugin. The availability of these operating modes will depend on your web browser and operating system. The table below provides a high-level comparison of the operating modes.
| Low-bandwidth mode | WebRTC mode | |
|---|---|---|
| Compatible operating systems | Windows, Linux, macOS, iOS, Android | Windows, Linux, macOS, iOS, Android |
| Compatible web browsers | Most modern web browsers (Microsoft Internet Explorer is not supported) |
The latest versions of Mozilla Firefox, Microsoft Edge, Safari (desktop and mobile), and Google Chrome (version 66 or higher on a desktop or mobile device) |
| Network requirements | Works well even on slow connections between the web browser and the Orchid Core VMS server | Prior to version 23.3, WebRTC required a good connection between the web browser and the Orchid Core VMS Server. Orchid versions 23.3 and greater should work well even if the connection between the web browser and Orchid is marginal (as long as WebRTC retransmission is enabled). |
| Video decoding | Decoding is done on the Orchid Core VMS server | Decoding is done on the client machine |
| Additional configuration required for viewing servers behind a firewall | None (assuming web interface is already accessible) | STUN server |
| Video quality | Frame rate that throttles to match available bandwidth | Native, unthrottled frame rate |
| Supported video file types | H264, H.265, JPEG, MPEG4 | H264 |
| Audio support | No | No |
| PTZ camera support | Yes | Yes |
| Video statistics | Yes (Minimal) | Yes (Overload) |
| Mode is selectable (at sign in and per Player) | Yes | Yes |
| Mode indicator |  |
