Symptoms
- Nighttime video looks grainy, dark, or washed out
- Visible glare or a bright blob in the footage at night
- Faces are unrecognizable after dark
- Daytime video looks fine but night is unusable
Likely causes
- CommonDirty or smudged camera lensDust, water spots, or fingerprints scatter infrared light and blur night footage badly.
- CommonNearby porch light or reflective surface causing glareA light source too close to the camera can wash out the infrared image.
- PossibleDoorbell mounted too far or at a poor angle from the walkwayInfrared range is limited, so distant subjects will look grainy regardless of settings.
- PossibleLow-light or night vision setting not optimizedSome apps let you adjust night mode sensitivity or force color night vision, which needs external light.
- Less commonAging or damaged infrared LEDsInfrared emitters can dim or fail after years of use.
What to do
- Wipe the camera lens with a clean, soft, dry microfiber cloth.
- Check for a nearby porch or motion light shining directly at the doorbell and reposition or dim it.
- Confirm the doorbell is mounted at the recommended height and angle from the manufacturer.
- Open the app's night vision or video quality settings and try switching between infrared and color night modes.
- Add a dedicated porch light on a separate schedule to improve color night vision if your model supports it.
- Clean any protective cover or weatherproof housing over the lens as well.
- If footage is still poor, check for a firmware update that may include image processing improvements.
Tools and parts
- Microfiber cloth
When to call a pro
If night vision stays poor after cleaning and lighting changes, the infrared LEDs may be failing and the unit likely needs manufacturer service.
