Working just fine.

Hi @isbjerg_533024393896188

On the newer camera firmwares (3.1 an later) some features are disabled by deafault - such as ONVIF. This is for security reasons. I do not recommend to use ONVIF with SS 9.0 as Advanced Events wont be detected and that is probably the strogest feature of this brand of camera.

I always setup a new camera using the Reolink Windows Client - Link to the latest 8.7.3 here:
https://home-cdn.reolink.us/files/client/electron-release/Reolink%20Setup%208.7.3.exe

That client easily discovers my Camera. I then note it's IP address and create a user inside the camera that I use for https connections from Surveillance Station (SS) and to the camera.
I go into settings -> Network -> Advanced -> Port setting and make sure to enable RTMP, HTTPS, RTSP using their default ports. I Leave HTTP and ONVIF disabled.

Hope this helps.

I have a setup with SS 9.01 and four Reolink Cams. One being RLC-810A and three being RLC-820A. I believe 810 and 820 share the same code and hw base.

I never setup my cams using ONVIF. I select the cams manually using IP-address, brand (Reolink) and model (RLC-810A). This way I ensure I get the Synology built-in advanced features such as Person, vehicle and per detection, which by the way works flawlessly in 4K resolution. I do always create a seperate userid inside the camera for my SS9 to authenticate. This is to avoid using the standard "Admin" account which does not bring much security in my view. I setup that user under System -> User-management in the web-client of the cams. Be sure to create such as user as administrator since SS9 needs to be able to manipulate camera settings as you set them under in SS9.
On my cameras I have enabled nothing but HTTPS on port 443 and RTSP on port 554. I did that using the web-interface on cameras (you can also use the Reolink Client).

In the SS9 IP Cam settings App (under information) I also made sure to select Firmware: >= FW 3.0.0.250_21040803 during setup. Under Advanced I simply selected:
Transport protocol: Auto
Keep-alive methid: Options (default)
Streaming source information: RTSP
Frame time correction: By streaming

Under Event detection and Advanced detection I can slect Person, Vehicle and Pet as I see fit. This only becomes selectable when using non ONVIF (Hence why I don't use ONVIF).

I hope this helps.

Hi,

You might want to check that the Synology firewall isn't blocking ingres traffic from your camera.

I am running SS 9.0 and rather than using the ONVIF protocol for my RLC-810a I selected my cameras manually. This gave me more options in regards to Smart events over ONVIF. Be sure to have the latest Device Pack (6.0.1-4402) installed in SS 9.0.
