🔄 Try this first — Unplug the Blink Arc power cable from the wall socket, wait 10 seconds, then plug it back in. Both cameras will restart automatically. Also restart your router by unplugging it for 30 seconds.

If your Blink Arc is showing this problem, working through the checks below in order will resolve it in the large majority of cases.

What This Problem Means

The Blink Arc uses colour (ambient light required) + 850nm IR for night-time monitoring. When it 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 washed out
  • Night vision not activating automatically
  • Image switches between colour and black and white unexpectedly

Safe Checks You Can Try

1. Check night vision settings

Open the app and ensure Night Vision is set to Auto or On.

2. Check for light interference

A nearby bright light source pointing directly into the lens can prevent night vision from activating or cause an overexposed image.

3. Clean the lens

Dust, condensation, cobwebs or fingerprints on the lens are the most common cause of blurry night vision. Clean gently with a soft, dry cloth.

4. Restart the camera

Unplug the Blink Arc power cable from the wall socket, wait 10 seconds, then plug it back in. Both cameras will restart automatically. Also restart your router by unplugging it for 30 seconds. A firmware glitch can occasionally prevent night vision from switching correctly.
