Sorry for the inconvenience. Your NVR’s firmware is already the latest one. If you want to upgrade the camera's firmware, you may need to do it via the monitor. Do you connect your NVR to a monitor? If yes, please refer to this article: https://support.reolink.com/hc/en-us/articles/360005131094-Upgrade-Firmware-via-PoE-NVR
