Question About VIGI NVR1008H 8-Channel NVR

Hello,
We are currently using the VIGI NVR1008H 8-Channel NVR.
I am writing to ask a few questions regarding this product.
According to the official documentation, whether the hardware version is 2.20 or 2.30, the NVR should be able to recognize devices and perform recording using the ONVIF protocol. Also, when an event trigger occurs from an on-device edge board, it should be possible to send a recording signal to the NVR.
However, this function does not work on hardware version 2.20, so I would like to inquire about this issue. The function appeared to work on hardware version 2.30. We also have previous delivery experience using the VIGI NVR1016H 16-Channel NVR.
In addition, we need to connect third-party devices, including third-party cameras and an edge board. When an event occurs, a signal needs to be sent to the NVR for recording. However, this is currently not working on hardware version 2.20.
If there is someone who can provide a professional technical answer regarding this matter, or if you could provide the appropriate contact email address for this inquiry, I would greatly appreciate it.
