the camera's night vision is just a bright white blob in the middle of the screen, can't see anything.

Diagnosis

The "white blob" effect on the Arlo Essential Indoor Camera (2nd Gen) is a classic case of Infrared (IR) light saturation, commonly known as "IR bounce-back." The camera utilizes an array of IR LEDs to illuminate the room in total darkness. When these LEDs fire, the light travels in a straight line; if that light hits a reflective surface—such as a window pane, a mirror, a glossy picture frame, or even a polished white wall—it bounces directly back into the lens. Because the sensor is tuned for high sensitivity in night mode, this reflected light creates a massive overexposure bloom. This "white-out" effect obscures the rest of the image because the camera's auto-exposure attempts to compensate for the bright spot by darkening the rest of the frame, leaving you with a glowing orb and a black background. You can confirm this by placing a piece of dark cardboard or a cloth directly in front of the camera's lens to see if the bloom disappears when the reflection is blocked. In some cases, this is caused by "internal reflection" if the camera is placed inside a plastic enclosure or behind a glass partition. The IR light hits the glass/plastic, reflects inward, and blinds the sensor before the light ever reaches the room.

How to Fix It

To eliminate the white blob and restore clear night vision, follow these precise repositioning and configuration steps:

1. Identify the Reflective Trigger: Look directly in front of the lens. Check for windows, mirrors, or high-gloss furniture within 5 feet of the camera. Even a glass vase or a metallic lamp base can cause this.
2. Adjust the Angle: Tilt the camera downward by 5-10 degrees. Since IR light travels in a cone, angling the camera slightly toward the floor often redirects the reflection away from the lens axis.
3. Increase the Distance: Move the camera at least 3 feet away from any wall or object. If the camera is tucked into a tight corner, the IR light may be bouncing off the adjacent wall.
4. Clear the Lens: Use a clean, dry microfiber cloth to wipe the lens and the surrounding IR emitter window. A smudge of oil or a fingerprint can catch the IR light and create a localized blur/blob.
5. Disable IR (If Necessary): If you have an external light source in the room, go into the Arlo App > Settings > Device Settings > Video Settings > Night Vision and switch from "Auto" to "Off" to see if the image clears.

If That Didn't Work

• Remove Protective Films: Check the lens for the factory-installed translucent plastic shipping film. Many users peel the outer case film but leave a tiny, circular protective sticker over the lens itself. This film is highly reflective to IR light and will cause a permanent white blur in the center of the screen.
• Check for "IR Leakage": If the camera is mounted inside a plastic or glass housing, the IR LEDs are reflecting off the interior of that housing. You must remove the housing or create a "mask" (a black foam gasket) between the lens and the glass to prevent the light from bouncing back.
• Test for Hardware Failure: Move the camera to a completely open room with no walls within 10 feet. If the white blob persists in a wide-open space, the IR cut filter (the mechanical piece that slides over the lens during the day) may be stuck in a halfway position, causing internal light leakage.
• Power Cycle and Firmware Sync: Perform a hard reset by holding the reset button for 15 seconds. This forces the camera to recalibrate its light sensors and can occasionally resolve software-driven exposure glitches.

Heads Up

• Avoid Window Placement: Never point an Arlo Essential camera directly through a window at night. The glass acts as a mirror for IR light, making the camera useless and potentially alerting people outside to the camera's presence via the glowing red LEDs.
• Dust Accumulation: Dust particles floating directly in front of the lens can appear as glowing white "orbs" or "blobs" during night vision. Use a can of compressed air to clean the lens area monthly.
• Lighting Balance: If you have a motion-activated porch light or a dim nightlight, the camera may struggle to switch between Day and Night mode, causing a "flicker" or a temporary white bloom as the IR filter engages.
