You check your security footage from last night — and instead of a clear image, it’s a mess of glare, ghostly fog, or pure darkness. Sound familiar?

You might think your camera’s night vision is broken, but the real problem could be much simpler: your infrared (IR) settings — and how your camera is installed.

Why Your Night Vision Looks Bad

Most smart cameras use infrared light (IR LEDs) to illuminate their view in darkness. But if that light bounces off the wrong surface — like glass, walls, or raindrops — it comes back into the lens and creates glare.

The result? White haze, blur, or washed-out subjects — even if the camera is technically working fine.

Key Causes of IR Glare or Bad Night Footage

• Camera facing a window — IR light reflects off the glass back into the lens
• Nearby walls or surfaces — especially if they’re light-colored or glossy
• Incorrect brightness or IR intensity settings
• Dirty lens or water droplets on the IR LEDs

How to Fix It (Step-by-Step)

1. Avoid Mounting Cameras Behind Glass

If your camera is inside and pointed through a window, you’re guaranteed to get IR bounce-back.

Fix: Mount the camera outdoors or disable IR mode entirely and use external lighting outside instead.

2. Angle the Camera Away from Walls

IR glare often happens when walls are too close to the camera and reflect the light unevenly.

Fix: Slightly tilt or reposition the camera to avoid direct reflections off nearby objects — especially white walls, pillars, or fences.

3. Adjust Infrared Brightness

Some smart cameras (like Eufy, Reolink, and even some Ring models) allow you to manually adjust the IR brightness or sensitivity.

Fix:

• Lower the IR LED brightness to reduce blowout
• Use “Auto IR” mode if available to adapt based on ambient light

4. Clean the Lens and IR LEDs

Even a small layer of dust, oil, or fog can scatter IR light badly.

Fix: Use a microfiber cloth to clean the lens regularly. After rain or high humidity, wipe off any condensation.

5. Consider External IR Floodlights

Want night vision without the built-in IR issues? Use a separate infrared floodlight — the camera can still “see” in the dark, but the IR source is now placed further away, reducing glare.

Bonus: You can also use low-lumen outdoor LED lighting to supplement vision without creating harsh shadows.

Still Seeing Issues? Try This Last Trick:

Switch to black & white night mode instead of “smart color” mode. Some smart cameras try to process color at night, which introduces extra noise or blur. Monochrome mode is often cleaner and more stable.

Final Thoughts

Bad night vision doesn’t always mean bad hardware. Most of the time, it’s a small setting or installation mistake that’s ruining your footage.

With a few tweaks — and maybe a better angle or wipe-down — your smart camera can finally do what it’s meant to do: protect your space clearly, even after dark.
