Overexposed image. Unable to see anything during the

Jiří

Hello, I have just installed my first Reolink camera (RLC-520A) and compared to the old unbranded one I can barely see anything during the day. The image is extremely overexposed even when there is no direct sunlight while a really cloudy dark day.
I have tried this troubleshooting: https://support.reolink.com/hc/en-us/articles/900002175303-Overexposed-Image with no luck, the setting just makes the image darker or lighter with the same result of not seeing anything.
I have not changed any image settings, I just connected the camera to ethernet, and the camera connected to my Reolink APP and Client. I have also tried to make every setting default, but still with the same results. I cant imagine a sunny day, the image is going to be white screen. I have Reolink APP, Reolink Client, BlueIris, AgentDVR, and iSpy, none of them is able to auto-calibrate this image. Can anyone help me? Is the camera sensor damaged or what should I try next?

I had the exact same issue with an RLC-810A and RLC-1220A.
I resolved this issue with the RLC-810A a few days ago.
I tried various adjustments to Exposure, Backlight and 3D DNR. Nothing worked.
About to give up, I decided to try less likely settings. I changed “Anti-flicker” from Auto to 50HZ. Bingo! Exposure problem fixed.
Why? I don’t know.
I set it to 60HZ, still looked good.
I set it back to Auto, still looked good.

To confirm this “fix”, I went to my RLC-1220A which had the same over-exposure issue. I confirmed the picture was still over-exposed and then changed “Anti-flicker” from Auto to 50HZ. The issue fixed again.

See before/after photos below for both cameras.

There must be a bug in the software / firmware.

See before and after photos attached.

Hello,

I have exactly the same conclusion as you on the RLC-820A and RLC-822A models.
I leave on 60 Hz and everything is correct.

Other parameter change.
From "Camera" -> "Display" -> "Advenced" -> "Backlight"

I changed the "Backlight" parameter to "Dynamic Range" and 85.

i have better night vision like this.

Bye

Thank you for the advice! I have finally managed to update the firmware, the app did not show any new versions so I had to manually upload the firmware. It seems like it really changed all the settings you mentioned, so it works now as it supposed
