Cameras disappear after a few minutes of Live View

[James_Wright]

Hi all, Cameras display correctly on startup, then drop out after 5–10 minutes. Rebooting the NVR restores them temporarily. Is this a resource limitation?
Thanks in advance.

Good day, James_Wright,
This is commonly related to NVR performance limitations. While an NVR may support high-resolution cameras, it may not support multiple channels running at maximum resolution and bitrate simultaneously. Please reduce camera resolution, frame rate, or bitrate and confirm the recorder’s decoding capabilities in the datasheet. Make sure the recorder is switching live view to substream when viewing more than 4 cameras.
