If the camera image is too dark for you, you can brighten it both via Reolink App and Reolink Client. Here is a simple guide on how to set it up.
Applies to: All Reolink cameras except for Argus 2 and Argus Pro.
On Reolink App
Step 1. Launch Reolink App and log in to your camera. Go to Device Settings > Display page.
Step 2. Slide the slider to adjust the brightness of the camera. The closer to the right end, the brighter the image will be.
On Reolink Client (New Client)
Go to Device Settings > Display> Advanced. Adjust the Brightness by sliding the slider. The higher the value, the brighter the image will be.
