### Optimum System Load

**Recommended maximum channels and inputs**

Pearl Nano supports up to one 4K30 channel or one 1080p60 channel, built from up to two video sources total. Both sources can be local (HDMI and/or SDI, up to 4K60 4:2:2 8-bit each), or one of the two can be a single networked IP source (SRT or RTSP, up to 1080p30) — only one IP source can be ingested at a time. For example, 1 HDMI + 1 SRT is supported.

These recommendations are hardware limits and cannot be exceeded.

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

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 any channel that is 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.
