Reolink Duo 2 POE Camera / Black screen / NVR RLN16-410

[robert_5420]

Hello!

Unfortunately I have problems with two new cameras (Reolink Duo 2 POE).

Existing hardware:
1x NVR Reolink RLN16-410 V2 | 16 channels
6x Reolink RLC-820A and RLC-822a (2 years old)
2x Reolink Duo 2 POE (newly purchased)

Mobile phone:
On the mobile phone (Apple iPhone) the live video of all cameras and the playback of older recordings works perfectly.

NVR:
But the live video of the two cameras (Reolink Duo 2 POE) on the NVR remains a black screen. Older recordings are also a black screen when played.

What can I do?

Best regards from Germany,
Robert

@robert_5420 What is the fw of your NVR? Check out this link https://support.reolink.com/hc/en-us/articles/4410520891033-Which-NVR-Can-Work-with-Reolink-Duo-WiFi-PoE-/?source=search

"Please note that if your Duo 2 WiFi/PoE works with an NVR with Hw_H3MB18 Hw_N3MB01, and Hw_N2MB02 hardware, you need to upgrade your NVR's firmware to the latest version to view the video, and it can only support max. 6MP video resolution.
The decoding width of Hw_H3MB18 Hw_N3MB01, and Hw_N2MB02 hardware is 4096. Therefore, if you set the mainstream resolution as 4608*1728, the image cannot be displayed on full screen successfully. It is recommended to set the mainstream resolution as 4096*1536."

Ensure you have the latest fw on both DUO 2 and NVR. Go to their Reolink Download Center and check them out.

@joseph_1979 
The NVR (Hw_H3MB18) still had firmware 3.0.0.x. The NVR system reported that the firmware was up to date.

I have now updated to 3.4.0.x using a USB stick.

Everything works now.
Thank you very much for your help.

Best regards,
Robert
