Optimum System Load
While Pearl Nano is powerful, there is a limit to the number of concurrent tasks the onboard CPU can perform efficiently.
The number of concurrent tasks depends on many factors, such as:
- the number of video sources
- what frame rate and bitrate is used for a channel
- if the video output ports are used
- if a live monitor is connected to the HDMI output port (about the equivalent of an encoded 1920×1080@30 fps channel)
For best results, we recommend keeping System load usage under 70%.
Check CPU usage on Pearl Nano's front screen
To check the CPU usage from the front screen menu, repeatedly press the left arrow key on the control interface until the Menu screen displays.
Use the arrow and check mark keys to select System, and then select Device information to display the Device information screen.
Recommendations
If the system load is higher than recommended, you can:
- Disable the video output port (if unused).
- Stop channel(s) that are streaming or recording.
- Ensure video sources come in at the right resolution so that Pearl Nano doesn't have to up scale or down scale the video source.
