How to Fix Night Vision IR Glare and Washed-Out Footage

Your security camera looks sharp all day, then flips to night mode and the footage turns into a milky white haze where the centre of the frame should be. That glow is IR wash: the camera's own infrared LEDs firing into a nearby wall, glass pane or overhanging soffit and bouncing straight back into the lens, blinding the sensor it is supposed to feed.

Quick Answer

Pull the camera away from whatever the IR is reflecting off. Mount it on an offset bracket so the LEDs clear nearby walls and soffits, keep at least a metre of clearance, and for cameras behind glass either disable the built-in IR and use a separate outdoor illuminator, or mount the lens flush to the glass. Cleaning the dome of webs and bugs fixes a surprising share of cases too.

Why the picture washes out at night

In daylight the camera uses visible light and the scene looks normal. After dark it switches on its infrared LEDs to illuminate the area. Those LEDs throw a lot of invisible light, and if anything reflective sits close to the lens, that light bounces back. A white wall right beside the mount, a soffit hanging just above, or a glass window in front of the lens all act like a mirror for IR, flooding the sensor and washing the image to white.

The closer the reflective surface, the worse it gets. A camera mounted flush against a wall blasts IR sideways into that wall and catches the reflection. A dome pressed near an overhang lights up the underside of the soffit. The sensor cannot tell reflected glare from real scene light, so it blows out.

The fixes that actually work

Start with distance. Use an offset wall-mount bracket, ideally one that pulls the camera 130mm or more off the surface, so the IR clears the wall instead of bouncing off it. Aim for at least a metre of clearance from any wall, and more for wide-angle units, which are especially prone to catching nearby reflections.

For cameras shooting through a window, the built-in IR is the usual culprit. Either turn the camera's IR off at night and add a separate IR illuminator positioned outside the glass, or mount the lens right against the window so no air gap lets light reflect back. Both remove the bounce that turns night footage milky. The bracket, illuminator and camera options to do this live across the smart home and appliances range.

Do not overlook simple maintenance. Spider webs catch IR brilliantly and are invisible in daylight, and dead insects build up on a dome over weeks. A regular wipe of the lens cover clears a large number of reflection problems before you touch the mount, and the cleaning gear and cabling spares for that are quick to find in the accessories best sellers.

Frequently Asked Questions

What exactly is IR wash?

IR wash is when a camera's infrared night-vision LEDs reflect off a nearby surface, a wall, soffit or glass, back into the lens. The sensor reads that reflected glare as light and blows the image out to a washed-out white.

How far should a camera be from a wall to avoid glare?

Aim for at least a metre of clearance, and more for wide-angle or fisheye cameras. An offset bracket that pulls the camera 130mm or more off the surface is the most effective fix.

Why is footage washed out only through a window?

The built-in IR reflects off the glass directly in front of the lens. Disable the camera's IR and use an external illuminator, or mount the lens flush against the glass so there is no gap for light to bounce back.

Can a dirty camera cause washed-out night video?

Yes. Spider webs catch IR strongly and are invisible by day, and dead insects accumulate on the dome. Cleaning the cover regularly resolves a surprising number of glare issues on its own.

Will turning off IR ruin my night vision?

Only if you have no other light source. The trick is to replace the close-in built-in LEDs with a separate IR illuminator placed away from reflective surfaces, so you keep night vision without the bounce.
