:man\_mage: **Tips**:&#x20;

1. If system mode is 1\*1080P\@50/60, then it can be set at most 60fps.
2. Set lower Key interval(GOP) if better image quality is required.
3. It's recommended to set lower bitrate like 500Kbits/s at the very beginning if your local bandwidth is not enough.
4. If it's required to view image directly in ODM(ONVIF Device Manager), it's necessary to disable&#x20;
