Visual & Thermal Privacy Systems

Vaydr builds privacy technology for a world where surveillance no longer relies on human observers but on algorithms instead.

Modern systems do not “see” faces or bodies the way people do. They analyze geometry, symmetry, shading, reflectivity, and heat patterns across multiple spectrums of light.

Vaydr products are engineered to interfere with those inputs.

Part I: How Modern Facial Recognition Works

What Facial Recognition Systems Look For

Most contemporary facial recognition systems rely on three core inputs:

1. Geometry

The spatial relationship between facial landmarks such as:

  • Eye spacing

  • Nose width and length

  • Jawline shape

  • Brow structure

These measurements form a mathematical face model.

2. Symmetry

Human faces are highly symmetrical. Algorithms look for:

  • Balanced landmark placement

  • Consistent ratios across both sides of the face

The more symmetry detected, the higher the confidence score.

3. Shading & Reflectivity

This is where most people misunderstand the technology.

Facial recognition systems do not rely on visible light alone.

They actively use:

  • Visible spectrum (VIS)

  • Infrared (IR)

  • Near-infrared (NIR) illumination

Many cameras emit NIR light and analyze how it reflects off skin, bone, and soft tissue to improve accuracy even in low light.

Why Hats & Normal Sunglasses Help (But Aren’t Enough)

Hats and sunglasses reduce facial recognition accuracy by:

  • Breaking facial geometry

  • Obscuring landmarks

  • Introducing shadow

However, most sunglasses only affect visible light.

This means:

  • The face still reflects near-infrared light

  • Algorithms can reconstruct facial geometry using NIR data

  • The user appears “exposed” under infrared illumination

This is why conventional sunglasses often fail against modern systems.

Part II: The Vaydr Difference & GLX Lens Technology

Blocking Facial Recognition Requires Blocking Two Spectrums

To meaningfully interfere with facial recognition, you must disrupt:

  1. Visible spectrum cues

  2. Near-infrared reflectivity

Vaydr GLX lenses are designed to do both.

Near-Infrared (NIR): The Critical Range

The most important spectrum for modern facial recognition is near-infrared light between approximately 780–1400 nanometers (nm).

This range is:

  • Invisible to the human eye

  • Actively used by surveillance cameras

  • Rarely filtered by consumer eyewear

Most sunglasses do not block this range. They appear dark to humans but are exposed to machines.

Vaydr GLX lenses use selective wavelength filtering to:

  • Reduce reflectivity in key NIR bands

  • Alter visible-light contrast and shading

  • Disrupt algorithmic landmark consistency

Rather than blocking all light, GLX lenses:

  • Filter specific wavelengths

  • Allow others through for safe, wearable vision

  • Maintain everyday usability

This creates a face that is less consistent, less symmetrical, and harder to model for certain consumer-grade facial recognition systems. Our sunglasses also have the added benefit of blocking UV and blue light.

Best Practices: How to Use Vaydr Sunglasses Effectively

Technology works best when paired with behavior.

For Best Results:

  • Wear sunglasses fully seated on the face

  • Pair with a hat or brim when possible

  • Avoid standing directly under fixed cameras

  • Minimize prolonged stationary exposure

  • Be mindful of posture and head angle

Vaydr sunglasses are designed for civilian, everyday environments, not advanced or government-grade systems.

Part III: Thermal Surveillance, The Next Frontier

Why Thermal Optics Matter

Thermal imaging is rapidly becoming:

  • Cheaper

  • Smaller

  • More widely available

What was once limited to military or industrial use is now accessible to civilians, security teams, and private operators.

Thermal systems do not see faces. They see heat contrast.

This makes thermal surveillance one of the fastest-growing privacy threats.

Two Problems Must Be Solved

Effective thermal concealment requires addressing two detection layers:

1. Visible Detection

If a person is visually obvious, thermal concealment alone is not enough.

Vaydr anti-thermal blankets use PrairieVeil™ camouflage, designed to:

  • Break up outlines

  • Match natural environments

  • Reduce visual contrast

2. Thermal Detection

Thermal optics detect heat transfer, not objects.

Vaydr blankets use a specialized lining system designed to:

  • Create an internal air gap

  • Slow and diffuse heat transmission

  • Reduce clean thermal outlines

Heat is not eliminated, it is spread and softened, making detection more difficult under certain conditions.

Enhancing Thermal Effectiveness

Thermal performance can be improved by:

  • Introducing natural foliage between the blanket and environment

  • Avoiding direct ground contact with warm surfaces

  • Minimizing movement

  • Allowing heat to equalize over time

Layering matters.

Field Use: Basic Rigging & Setup Concepts

These techniques are for civilian preparedness and concealment, not combat or illegal activity.

Quick Ranger-Style Shelter Setup

  • Use corners to tie off to branches or stakes

  • Create airflow beneath the blanket

  • Avoid tight wrapping against the body

  • Leave small ventilation gaps

Knotting Basics

  • Overhand knot for quick tie-offs

  • Bowline or trucker’s hitch for tensioned lines

  • Avoid compressing insulation layers

Fast Field Folding (Recommended Method)

  1. Lay blanket flat

  2. Fold lengthwise into thirds

  3. Fold again to desired width

  4. Roll tightly from one end

  5. Secure with elastic cord or strap

Fast folding preserves the lining structure and speeds redeployment.

What Vaydr Is And Is Not

Vaydr Is:

  • Privacy-enhancing technology

  • Designed to reduce detection confidence

  • Built for civilian use

  • Most effective as part of a layered approach

Vaydr Is Not:

  • A guarantee of invisibility

  • Military or law-enforcement equipment

  • A substitute for awareness and behavior

  • Effective against all surveillance systems

Surveillance systems are evolving quickly.

Vaydr exists to help people understand how they are seen and reduce unnecessary exposure.

Privacy isn’t about hiding from the world, it’s about choosing when and how you are seen.
