Symptoms

  • Nighttime footage is completely black
  • Video is extremely grainy or washed out after dark
  • Bright white glare covers part of the frame at night
  • Night vision worked before but stopped recently

Likely causes

  • CommonDirty or obstructed lensDust, spiderwebs, or water spots block or scatter infrared light and can make footage look black or foggy.
  • CommonNearby light source confusing the day/night sensorA porch light or streetlight can trick the camera into staying in day mode when it's actually dark, or cause glare.
  • PossibleInfrared LEDs not activating due to a settings or firmware issueNight mode may need to be manually enabled or reset if it's stuck in the wrong mode.
  • PossibleCamera mounted behind glass or a screenInfrared light reflects off glass and screens, badly degrading night vision.
  • Less commonFailing infrared LEDs or light sensorAfter years of outdoor use, the IR emitters or ambient light sensor can wear out.

What to do

  1. Clean the lens thoroughly with a soft, dry microfiber cloth, including any protective dome or cover.
  2. Check for spiderwebs near the lens, which are a very common and often-missed cause of blurry or blocked night footage.
  3. Move or dim any nearby lights that shine directly at the camera.
  4. Never mount the camera behind glass or a window screen if avoidable, since infrared reflects off both.
  5. Open the app and confirm night vision mode is set to automatic or on, not off.
  6. Restart the camera and check for a firmware update.
  7. If the issue persists after cleaning and repositioning, note that the infrared hardware may be failing.

Tools and parts

  • Microfiber cloth

When to call a pro

If night vision stays broken after cleaning, repositioning, and a firmware check, the camera likely needs manufacturer repair or replacement.
