Causes of Blurry or Washed-Out Nighttime Security Camera Footage: How to Check for Reflections and Positioning Issues

Even if you have installed a camera for monitoring or security, you may find the entire screen looking whitish or the outlines of people becoming unclear at night. Installation issues that went unnoticed during the bright daytime can sometimes manifest during night recording. This article is not a comparison between infrared and full-color models, but a checklist for when the footage from an already installed camera is difficult to see only at night. Please check the items one by one, ensuring you protect your privacy within the shooting range and maintain safety while working at heights.

First, categorize the symptoms: When and where does it turn white?

The suspected cause differs depending on whether the entire screen is uniformly white or if a halo of light appears in only one part. If it happens only the moment the camera switches to night mode, it may be related to reflections from infrared or auxiliary lighting used in the dark. If the condition worsens only on rainy nights, check for water droplets on the lens cover or reflections from wet surfaces directly in front of the camera. If the image is blurry during both day and night, focus, communication quality, and the state of the lens are also possibilities.

It is easier to narrow down the cause if you record one image of the same location during the day and one at night via the app and compare the areas where the whiteness appears. However, please do not send images showing the faces of family members or neighbors, or your address, to public consultation services. If sharing with support, narrow it down to the necessary scope to protect personal information.

Beware of reflections when recording at night through a window

When recording outdoors from indoors through a window, the camera's night lighting may reflect off the glass, appearing as white light or a cloudiness nearby. The appearance will also vary depending on indoor lighting, glass smudges, and double-pane window structures. While it may be bright outside during the day, indoor reflections are more noticeable at night, so first check if the whiteness increases when switching to night mode.

When changing your recording method from a window, first confirm whether the model is intended for outdoor use and whether power and communication can be secured. Even with waterproof specifications, there are conditions for handling charging terminals and wiring. While methods such as pressing the camera directly against the glass or turning off night lighting are sometimes suggested, the effectiveness varies by model and may reduce night vision capabilities. Base any setting changes on a comparison of footage from before and after.

Nearby walls, eaves, and spiderwebs also affect footage

If a white wall, overhanging eave, or pillar right next to the camera strongly reflects the night light, a bright band may appear at the edge of the screen. Sometimes, slightly changing the angle of the camera improves this, but be careful not to shift the camera away from the areas you originally intended to monitor, such as your entrance or walkway. Verify the angle of view both day and night after adjustment.

If there are thin spiderwebs or insects near the lens, they may appear as white glowing dots or lines at night. Since dirt accumulates easily in outdoor installations, inspect the surface periodically according to the instruction manual. Do not climb high ladders at night; check by safe means during daylight hours. If the installation is in a high place, do not stretch to reach it, and consider consulting an installation professional.

Safely check for water droplets and dirt

Immediately after rain or on days with large temperature fluctuations between morning and evening, there may be water droplets on the camera's transparent cover. Ensure the power and cables are safe to handle, and clean the surface with a soft cloth according to the product's maintenance instructions. Avoid using abrasives or harsh chemicals as they may damage the coating. If you see cloudiness inside the cover, do not open the unit yourself; consult the retailer.

IP ratings indicate protection performance under specific conditions and are not a guarantee of unlimited resistance to rain from any direction. Also, check if wiring and connection points are in positions where they are prone to catching water. Do not touch dropped or damaged equipment while it is plugged in, and follow the manual for safety.

How to isolate settings and network issues?

While whiteness is often caused by lighting or reflections, issues such as grainy footage, freezes, or loss of detail may be caused by network influence. If only the live feed is grainy but the recording is clear, check your communication status or the app's display quality settings. If the recording is also white, prioritize checking the installation location or the lens. However, since recording quality and storage methods vary by model, do not diagnose the cause based on a single symptom alone.

If you change the night vision mode, auxiliary light settings, and camera angle all at once, you won't know what caused the improvement. Change one item at a time and compare the nighttime images. Since setting names and procedures change with model and app updates, follow the provided manual and app displays. If changing settings alters the recording range or quality, re-evaluate whether it still meets your initial objectives.

If it does not improve, organize the situation before consulting

If the night footage does not improve after safe cleaning, adjustment of the installation angle, and checking settings, record day and night footage under the same conditions, document the installation location, and note whether there has been rain or if the device has been dropped, then consult the retailer. If moisture is visible inside the device, or if there is an unusual odor or overheating, stop using the device. Disassembling the unit may affect its waterproof performance or warranty.
