You check an overnight alert and spot a pale ball drifting across the frame. It may float slowly, dart past the lens or glow beside a wall. Seeing orbs on security camera footage can be unsettling, particularly when the garden looked empty at the time. In most cases, however, the explanation is ordinary: moisture, dust, pollen, insects or reflected light close to the lens.
This guide explains why those small objects look so large, how Britain’s damp and changeable weather can affect night footage, and how to trace the cause without guesswork. You will also learn practical ways to improve the image while keeping the camera aimed responsibly.

What Are Orbs on Security Camera Footage?
Orbs on security camera footage are usually not solid objects. They are often camera artefacts caused by nearby particles reflecting light back into the lens. They may appear as white circles, translucent spots, or short streaks.
The effect is most common at night when cameras use infrared LEDs for night vision. Dust, insects, rain droplets, or moisture close to the lens can reflect infrared light and create bright, out-of-focus shapes known as backscatter.
Why Tiny Particles Look Like Large Glowing Circles
This happens because cameras focus on objects at a specific distance. A camera aimed at a gate or driveway may focus several metres away, while a small particle near the lens remains out of focus and appears as a large blur.
Infrared light makes these shapes more visible, while movement, lighting changes, and video compression can make them appear to move or disappear.
What Causes Orbs on Security Cameras?
We need to use timing, movement and location to narrow down the cause. Several sources can create similar circles, but their patterns are often different enough to distinguish on a short recording.
Rain, Drizzle, Mist, Fog and Dew
In the UK, wet weather is one of the most common causes. Rain and drizzle can appear as bright dots or streaks when drops pass through the infrared beam. Mist and fog can create softer patches by reflecting light close to the lens.
Dew or moisture on the camera cover may also create a fixed halo or blurry area.
Dust, Pollen and Airborne Debris
Dust, pollen, and other small particles can reflect infrared light and appear as floating spots. These are more common during dry weather, gardening, road activity, or nearby construction.
Flying Insects and Cobwebs
Insects such as moths, flies, and midges can pass close to the lens and appear as bright, blurred shapes. Their movement is often sudden and unpredictable.
Spider webs can create repeated arcs or swinging patterns because they catch dust and moisture.
Infrared Light Reflecting from Nearby Surfaces
Nearby surfaces can also reflect infrared light back into the camera. Walls, fences, roof edges, pipes, or other objects close to the lens may create bright circles, hazy areas, or washed-out sections.
This problem may only appear at night because infrared lighting is activated.
Street Lights, Porch Lights and Vehicle Headlights
External light sources can create lens flare that looks like an orb. Street lights, porch lights, and passing vehicles may produce bright circles or glare, especially when light reflects off wet surfaces, windows, or glossy materials.
How to Identify What Is Causing the Orb
Before changing settings or replacing equipment, review a few clips and look for patterns. The movement, timing, and appearance of the orb can often help identify the likely cause.
Check Whether the Orb Moves or Stays Still
Start by comparing several recordings. Use this table as a guide rather than a final diagnosis:
|
What you see |
Likely cause |
|
A single drifting shape |
Dust, pollen, or an insect |
|
Many bright dots during wet weather |
Rain, mist, or fog |
|
A curved or swinging line |
Cobweb or spider silk |
|
A fixed blurry patch |
Dirt, dew, or moisture on the lens cover |
|
A bright area near a wall or object |
Infrared reflection |
|
A circle appearing near a light source |
Lens flare |
Compare Day and Night Footage
Check whether the orb appears before or after night vision activates. If it is visible in both daytime and nighttime footage, it may be related to the lens cover or a physical mark. If it only appears at night, infrared light and nearby reflections are more likely causes.
Match the Recording to the Weather
Match the recording time with local weather. Rain, fog, wind, and insects can create changing patterns, while dirt, moisture marks, or nearby reflective surfaces usually create more consistent effects.
How to Reduce Orbs Appearing on a Security Camera
Once you identify the likely cause, start with simple changes and check the footage after each adjustment. This helps you understand which change improves the image.
Clean the Lens and Camera Housing Safely
Regular cleaning is one of the simplest ways to improve night-time image quality.
Follow these steps:
- Remove dust and cobwebs with a soft brush or air blower.
- Wipe the camera cover with a clean microfibre cloth.
- Use manufacturer-approved cleaning products when needed.
- Avoid abrasive materials that may scratch the cover.
Remove Cobwebs and Check the Area Regularly
Keep the area around the camera clear to maintain a clean field of view.
Check for:
- Cobwebs around the lens edge and mounting area
- Leaves or branches close to the camera
- Objects that block or reflect the camera’s view
Avoid applying insect sprays directly to the camera, as chemicals may damage the housing.
Adjust the Camera Angle or Position
Small changes to the camera angle can improve image quality.
When adjusting the position:
- Keep important areas within view.
- Avoid unnecessary coverage of neighbouring or public spaces.
- Check that nearby objects are not interfering with the view.
Adjust Night-Vision and Lighting Settings
If available, test different night-vision settings to find the clearest image.
Options may include:
- Adjusting infrared intensity
- Switching between night-vision modes
- Changing nearby lighting conditions
Detection settings cannot remove orbs, but adjusting activity zones may help reduce unnecessary alerts.
Check for Internal Condensation or Damage
If image issues continue after cleaning and adjustments, inspect the camera condition.
Look for:
- Persistent fogging inside the cover
- Signs of damaged seals
- Cracks or loose mounting points
Avoid opening sealed cameras unless instructed by the manufacturer. Contact support if internal damage is suspected.
How to Prevent Night-Footage Issues in UK Outdoor Areas
Beyond immediate fixes, good selection and placement make night footage easier to maintain. When comparing Security Cameras, match the device to the scene rather than choosing by resolution alone.
For exposed driveways and gardens, Outdoor Security Cameras need a suitable weather-resistance rating. That rating protects the hardware under stated conditions; it does not hide particles passing in front of the lens.
Focus on practical factors:
- Mounting position: Place the camera away from nearby surfaces, direct lights, and other potential sources of glare.
- Night vision: Compare infrared and colour night-vision options based on the lighting conditions around the property.
- Lighting: Consider both the direction and brightness of nearby lights to avoid overexposure.
- Detection features: Use activity zones and object detection to reduce unnecessary alerts.
- Recording and access: Ensure footage is stored reliably and the camera remains accessible for maintenance.
Plan the view before drilling and check it by day and night. If installation requires mains wiring or work at height, use an appropriately qualified professional.
Floodlight Camera E340 for Detailed Outdoor Monitoring
When night-time footage problems continue despite basic adjustments, choosing a camera with better coverage, lighting control, and recording options can make a difference. For fixed outdoor areas such as driveways and entrances, a floodlight camera can provide both visibility and context, helping you capture clearer footage when movement or environmental factors affect the image.
The Floodlight Camera E340 is designed for areas that need detailed outdoor monitoring. Its dual-camera system combines a 3K wide-angle view with a 2K telephoto view, allowing you to monitor a larger area while retaining closer details.
Key features include:
- Dual-camera coverage and tracking: The wide-angle and telephoto views work together with pan-and-tilt movement to monitor activity across larger outdoor spaces.
- Adjustable floodlights: Up to 2,000-lumen lighting can improve visibility after dark. Position the lights carefully to avoid reflections from nearby walls, windows, or other surfaces.
- Reliable recording and outdoor performance: The camera supports continuous recording with a microSD card or compatible HomeBase S380, while IP65 weather resistance and dual-band Wi-Fi 6 support outdoor installation.
The E340 requires hardwired AC power, so plan the installation location carefully before mounting. A suitable viewing angle, controlled lighting direction, and regular maintenance can help improve night-time footage, although rain, insects, dust, and other environmental factors may still affect recordings.

Conclusion
Ultimately, orbs on security camera recordings are best treated as visual clues rather than mysterious objects. Look at how each shape moves, when it appears and what changed around the property. That approach helps you choose a proportionate response instead of replacing equipment that may be working normally.
Start with a dry, clean lens and a clear space around the housing. Then compare night modes, weather and nearby lighting. If you reposition the camera, preserve the security view while limiting unnecessary coverage beyond your boundary. Persistent clouding inside the unit, damaged seals or electrical concerns deserve professional attention. With a little observation and routine care, night footage can remain clearer and more useful through changing UK conditions.
FAQs
Are Orbs on Security Cameras Paranormal?
No, orbs on security cameras are usually not paranormal. In most cases, they are optical effects created when dust, pollen, water droplets, cobwebs or small insects pass close to the lens. Infrared night-vision light reflects from these nearby particles, making them appear as large, glowing circles. Check the lens, weather and surrounding area before assuming anything unusual.
Why Do Orbs Appear Only at Night?
Orbs often appear at night because many security cameras activate infrared night vision in low light. Dust, moisture, pollen or insects close to the lens reflect this infrared light back into the camera, creating bright, blurred circles. During the day, infrared LEDs are normally inactive, and stronger ambient light makes these faint reflections much less noticeable.
Can Rain and Fog Cause White Orbs on CCTV?
Yes, rain, fog, mist and humid conditions can create white orbs on CCTV footage. Water droplets passing close to the lens reflect infrared night-vision light, making tiny droplets look like glowing circles, streaks or blurry patches. If the effect appears mainly in wet weather and clears as conditions improve, airborne moisture is the likely cause.
Why Do Orbs Trigger Motion Alerts?
Orbs can trigger motion alerts because nearby dust, rain, pollen, insects or cobwebs may appear large and bright in night footage. As these objects move through the infrared beam, they change many image pixels at once. Basic motion detection may interpret that change as activity, while motion zones, lower sensitivity or person detection can reduce unnecessary alerts.
Will Cleaning the Lens Remove Camera Orbs?
Cleaning the lens may remove camera orbs when dirt, fingerprints, dried water marks or stuck debris on the cover causes the effect. Use a clean microfibre cloth and follow the camera’s care instructions. However, cleaning cannot stop airborne dust, pollen, rain, fog or insects passing close to the lens. If orbs keep moving, check the weather, cobwebs and nearby lighting instead.
