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

It sounds like the overexposed image issue might be due to a malfunctioning sensor or incorrect settings. Here are a few steps you can try:

Check Firmware: Ensure your camera firmware is up-to-date. Sometimes, firmware updates can fix image quality issues.
Adjust Exposure Settings: In the Reolink App or Client, try manually adjusting the exposure settings rather than relying on auto-calibration. Set it to a lower value to reduce overexposure.
Location and Angle: Check the placement of your camera. Sometimes, direct or reflective light sources can cause overexposure. Adjust the angle to see if it helps.
Reset the Camera: Perform a factory reset on the camera. This can sometimes resolve persistent issues by restoring the camera to its original settings.
Test Different Software: Since you're using multiple platforms (Reolink App, Reolink Client, BlueIris, AgentDVR, and iSpy), ensure all software is updated and check if any specific platform handles the exposure better.

If none of these solutions work, it might be a hardware issue. You could test the camera's sensor by running a white screen test or a full black screen test. This can help identify if the sensor is responsive to light changes correctly.
