Doorbell Camera Night Vision Not Working

Common Symptoms

• Doorbell camera shows completely black image at night
• Night image washed out or uniformly white (IR reflection)
• Camera image grainy or extremely dark at night
• Night vision works but image is heavily blurry
• Camera only shows image at night when a light is on nearby

Most Likely Causes

1. 1

   Camera Mounted Behind Glass — IR Reflection (Most Common)

   This is the most commonly misdiagnosed 'broken night vision' scenario. When a camera is mounted behind a window or glass storm door, the IR LEDs illuminate the glass surface instead of the scene in front of it. The reflected IR floods the sensor with light, producing a washed-out white image. Moving the camera outside the glass completely resolves this.

2. 2

   Night Vision Mode Disabled in App Settings

   Ring, Nest, Arlo, and Wyze cameras all have a night vision setting in the app that can be set to Auto, On, or Off. If accidentally set to Off, the IR LEDs don't activate in low light — resulting in a dark or black image. Check the camera's Video Settings in the app and confirm Night Vision is set to Auto or On.

3. 3

   Bright External Light Source Washing Out the IR Image

   IR night vision is optimized for dark conditions. A porch light, street lamp, or neighbor's floodlight in the camera's field of view can overwhelm the auto-exposure, causing the IR-lit portion of the scene to appear dark while the bright light source blows out. Reposition the camera to exclude the bright source from the frame, or enable HDR mode if available.

4. 4

   IR LED Ring Failure

   The IR LEDs that illuminate the scene at night can fail over time, particularly in outdoor cameras exposed to temperature extremes. When IR LEDs fail, the image is completely dark in night vision mode even in a fully dark environment. You can verify LED failure by pointing a smartphone camera at the doorbell's IR LED ring in a dark room — a working IR LED ring will appear as a faint purple-white glow in the phone camera view.

Quick DIY Checks

1. 1Check for glass reflection first: if the camera is inside looking through a window or glass storm door, this is almost certainly the cause of a washed-out night image. Move the camera to an external surface that doesn't require imaging through glass. Even a thin storm door is enough to reflect IR light back into the lens.
2. 2Verify night vision mode in the app: open the camera's app (Ring → Device Settings → Video Settings → Night Vision; Wyze → Account → Wyze Cam → Night Vision; Arlo → Settings → Video Settings → Night Vision). Confirm it's set to Auto or On. If it was set to Off, toggle to Auto and test.
3. 3Clean the camera lens: use a soft microfiber cloth to wipe the lens dome. Outdoor cameras accumulate pollen, water spots, and spider webs on the lens that scatter IR light and reduce image clarity at night. Do not use paper towels — they scratch the lens coating.
