Reolink windows client doesn't show camera model

[jeremy xzm+reolink_178542373003497]

The windows client is v8.15.6.
The NVR device is RLN16-410 with FW v2.0.0.4732_1728_21062800.
I have 13 cameras attached to it. They are working alright.
However, I tired to view the camera's model number and upgrade their Firmware, but I cannot find any camera specific information from the Windows Client.
The camera setting page only shows Camera number, channel number.

I am expecting to see something similar to what's depicted in the maintenance page shown in this web page: https://support.reolink.com/hc/en-us/articles/900004550323-How-to-Upgrade-Firmware-via-Reolink-Client-New-Client-/
But my windows client has nothing for Camera under Maintenance.
What is going on? And how can I upate the camera firmware from Windows client?

@jeremy-xzm-reolink_178542373003497 That's because your cameras are connected directly to the NVR. To achieve that you need to connect the cameras to a POE switch.

So you need to upgrade the camera fw through the NVR. Follow this link https://support.reolink.com/hc/en-us/articles/360005131094-How-to-Upgrade-Firmware-via-PoE-NVRs/
