In this article we will discuss the performance differences between HD and SD streaming.
HD and SD
 |
- When you stream HD (High Definition), it will directly output from the camera. Therefore, if your camera is set to 4K resolution (3840 x 2160), the stream would be the same.
|
- When you stream SD (Standard Definition), it will downscale the resolution to less than HD quality (defined as 1080p and above).

Performance Differences
|
Here are the differences between the two modes Rhombus provides, keeping in mind that the R360's resolution differs from our other cameras (see below):
|
| HD (High Definition) |
SD (Standard Definition) |
- Uses resolution set on camera being displayed
- Higher bandwidth consumption
- Higher quality video for all cameras EXCEPT the R360:
- Non realtime resolution: user-configured resolution
- Realtime resolution: 1080p max
- Higher quality video for the R360 ONLY:
- Non realtime resolution: user-configured resolution
- Realtime resolution: 1440x1440
- More demanding on your machine
|
- Uses resolution set on camera being displayed
- Lower bandwidth consumption
- Lower quality video for all cameras EXCEPT the R360:
- Non realtime resolution: 360p
- Realtime resolution: 360p
- Lower quality video for the R360 ONLY:
- Non realtime resolution: 640x640
- Realtime resolution: 640x640
- Less demanding on your machine
- Only applies to cameras connected over WAN or in real time mode

Best Practices
It is important to note that choosing SD video over HD video can lead to better performance, but at the cost of video quality. If network performance and bandwidth are not a concern, it is better to go for the HD option.
