Why Is My Amcrest Camera Night Vision Blurry With Purple Tint or Washed Out Image

Problem Description

Your Amcrest security camera produces blurry, purple-tinted, or washed-out images during nighttime recording. The IR night vision may appear foggy, have a strong purple or pink color cast, or show extremely bright spots that wash out the entire image. Daytime video quality is normal but night vision is unusable.

Symptoms

• Night vision image has a strong purple or pink color cast
• IR illumination creates a bright white haze or fog in the image
• Objects close to the camera are overexposed and blown out at night
• Night vision image is blurry even though daytime video is sharp
• IR LEDs reflect off nearby surfaces creating a bright glare
• Camera switches between day and night mode rapidly at dusk

Recognize these? Here's what usually causes it.

Common Causes

• IR LEDs reflecting off a nearby wall, eave, or window surface
• Camera dome cover or lens has condensation or moisture buildup
• IR cut filter stuck and not switching properly between day and night
• Camera mounted too close to a reflective surface like siding or glass
• Spider webs or insects attracted to IR light covering the lens
• Night vision exposure settings set to auto instead of manual adjustment

Tools & Requirements

Step-by-Step Solution

1

Check for IR Reflection Sources

At night, view the camera live feed and look for any bright white areas washing out the image. IR LEDs reflect strongly off walls, roof eaves, window glass, and light-colored siding within 3 feet of the camera. Reposition the camera so no surfaces are within the IR beam path directly in front of or beside the lens. Even a small lip of a mounting surface can reflect enough IR to ruin the entire image.

Clean Lens and Dome Cover

Power off the camera and carefully remove the dome cover if applicable. Clean the inside and outside of the dome with a dry microfiber cloth. Check the actual lens surface for fingerprints, dust, or water spots. For bullet cameras, clean the front glass window. Any film or residue on the lens surface will scatter IR light and create a foggy or hazy night vision image. Use a lens cleaning pen for stubborn spots.

Address Condensation and Moisture

If you see fog or moisture droplets inside the dome or housing, the camera seal has been compromised. Remove the camera and dry it thoroughly indoors for 24 hours. Apply silicone sealant around the cable entry point and any seams where water could enter. Place a small silica gel desiccant packet inside the housing before resealing. For turret cameras, ensure the rubber gasket around the lens module is properly seated.

Adjust IR and Exposure Settings

Access the camera web interface and navigate to the Image or Video settings. Find the IR LED or Infrared section and reduce the IR intensity from Auto to a manual level, starting at 50 percent. Under Exposure settings, switch from Auto to Manual and reduce the gain value to lower noise in the image. Increase the shutter speed slightly if the image is too dark. These adjustments reduce the purple tint and overexposure common with auto settings.

5

Test and Fine-Tune at Night

After making adjustments, wait until full darkness and review the live feed. Walk through the camera field of view to check that people and objects are visible without being washed out. If the purple tint persists, the IR cut filter may be mechanically stuck. Try power cycling the camera which sometimes frees a stuck filter. If the filter is permanently stuck, the camera may need warranty replacement as the filter mechanism is not user-serviceable.
