In this article we will discuss the performance differences between HD and SD streaming
HD and SD
- HD - High Definition streaming is streaming the direct output of the camera (i.e. If the camera is set to output 4K then you will be viewing 4K)
- SD - Standard Definition is streaming that is set to a resolution that is less then HD (1080p and above)
Performance Differences
The differences between the two modes at Rhombus can HD streaming provides
- HD - Better quality at a higher performance demand
- Uses resolution set on camera being displayed
- Higher bandwidth consumption
- Higher quality video
- Non realtime resolution: 360p
- Realtime resolution: 1080p
- More demanding on your machine
- SD - Standard quality at a optimal performance demand
- Uses resolution set on camera being displayed
- Lower bandwidth consumption
- Lower quality video
- Non realtime resolution: 240p
- Realtime resolution: 360p
- Less demanding on your machine
- Only applies to cameras connected over WAN or in real time mode
Best Practices
When viewing video walls it is important to keep in mind that the SD video option leads to better performance at the sacrifice of video quality. If bandwidth or network performance aren't a concern than the HD option preferred.
