NINE40 / Security Glasses programDoc SG-OVR-01 · Rev 2026.10$225 a pair · 12 for $1,995
Covert AR eyewear for security, government and enterprise
They look like glasses. That is the point.
NINE40 Security Glasses put augmented reality inside frames that pass for everyday optical eyewear. There is no camera lens on the front and no glowing display, so a lobby, a checkpoint or a meeting room has nothing to notice. Your people move through the building with their information in view and their privacy intact.

Frame lineup
Four frames. None of them look like technology.
Each frame copies a style people already wear to work: an acetate classic, a metal executive frame, a thin office frame and a safety-style pair for facilities. Pick one per role, or mix them across a team so nobody stands out.

About these images. The frames are shown as design renders. Final materials, sizes, colors and lens options are confirmed with your team during the briefing. SG-4 is a safety-style design; we do not claim an ANSI Z87.1 or other impact rating for it today.
What you can't see
Everything that makes it AR stays out of sight.
Optics and sensors sit inside the frame
The parts are designed into the rims and temples, so the frame keeps the proportions of ordinary eyewear instead of the thick arms most smart glasses have.
Only the wearer sees the display
Information appears in the wearer's view. From across a desk or a corridor, the lenses are meant to read as plain clear lenses.
No camera lens on the front
There is no dot, cutout or glass bead on the front of the frame for anyone to spot.
No indicator glare
No status lights and no glowing edges to catch the eye in a dim room or show up on someone else's security camera.
Design intent, not certified specs. These are the goals the frames are built around. Ask for the current engineering status, sensor details and test results during a briefing.
On the job
Worn in places where a gadget would get noticed.
Illustrative images, not customers.
Works with Always Encrypted
The door checks that you're allowed in. It never learns who you are.
Paired with Always Encrypted, the glasses carry a credential instead of personal data. In participating buildings, encrypted access points on doors, elevators and turnstiles confirm authorization without the building ever receiving the wearer's identity.
- 01
Verify once
The wearer completes a one-time, encrypted identity verification with Always Encrypted.
- 02
Carry a credential
The glasses hold a credential that proves what the wearer is cleared for. Name, photo and ID numbers stay out of it.
- 03
Walk up to the door
An encrypted access point at the door, elevator or turnstile reads the credential as the wearer approaches.
- 04
The door opens
The building confirms the person is authorized and lets them through. The identity never leaves the credential.
What the building learns
- This credential is authorized here
- The access point it was presented at
What it never receives
- Name
- Face or photo
- Government ID number
- Home address
Access features need Always Encrypted access points installed at the building. Ask which sites participate, or how to add yours.
Fleet and team purchasing
Bought by the set. Run as one fleet.
Most orders are for teams: a security detail, a site staff, an agency office. We size the order around your roles and keep the glasses manageable after they ship.
A
Team sets
Order a set for a whole team and mix frames by role. Individuals can buy single units through the same request.
B
Provisioning
Glasses arrive set up for your organization, assigned to people or roles, so the first day is spent working instead of configuring.
C
Central management
Assign, reassign and retire units from one place when people join, change posts or leave.
D
Deployment support
Help with fitting, rollout and the Always Encrypted setup at your buildings, from the first site to the last.

Program questions
Straight answers.
How do we order?
Send the request form with the option you want. We confirm frames, sizes and lead time with you by email before anything ships.
What do they cost?
$225 for a single pair, or $1,995 for a dozen (12 pairs). Orders larger than a dozen and enterprise fleets get a custom quote.
Do you sell to individuals, or only to agencies and companies?
Both. Companies and agencies usually buy team sets. Individuals can ask about single units through the same form.
Which certifications do the glasses hold?
We don't list certifications on this page. If your program needs a specific standard, name it in your request and we'll tell you plainly where the product stands against it.
Will people be able to tell they're AR glasses?
The frames are designed so they can't: ordinary optical styles, no visible camera lens on the front and no glowing display. Treat that as the design goal it is, and ask to see the frames during a briefing.
Do the glasses need Always Encrypted?
No. The glasses are designed to work on their own. The privacy access features for doors, elevators and turnstiles need a building with Always Encrypted access points.
Is this the same product as NINE40 sunglasses?
No. NINE40 sunglasses are consumer privacy eyewear with a 940 nm lens. Security Glasses are a separate program for teams.
