If night vision is not working on your Reolink Video Doorbell PoE, working through the checks below will resolve the issue in most cases.
What This Problem Means
The Reolink Video Doorbell PoE uses IR LEDs for black-and-white night vision and spotlights for colour night vision. When night vision is not working, the image appears dark, blurry or washed out at night.
Common Symptoms
- Image appears completely dark at night
- Night vision image is blurry or has a pink/purple tint
- Night vision image is overexposed (white wash)
- Colour night vision not activating when expected
- IR mode not switching on in darkness
Safe Checks You Can Try
1. Check night vision settings
Open the Reolink app, go to Device Settings and check the Night Vision setting. Ensure it is set to Auto or Color/IR. In Auto mode the camera switches between colour and IR based on light levels.
2. Check for infrared interference
A nearby bright light source pointing directly into the camera lens can overexpose the night vision image. Try repositioning the camera or shielding it from direct light.
3. Clean the lens
Dust, condensation, cobwebs or fingerprints on the lens are the most common cause of blurry or dark night vision. Clean the lens with a soft, dry cloth.
4. Restart the device
Switch off the PoE switch or injector port supplying the doorbell for 10 seconds, then switch it back on. Wait 60 seconds for the doorbell to restart. Restart your router by unplugging it for 30 seconds too. A firmware glitch can occasionally prevent the IR cut filter from switching correctly between day and night modes.
