Silens
The SILENS FSM-1: a machined aluminium frame holding a camera, a phone and a speaker. The screen shows an outline of a person and the words: Glasses, please.

Nobody starts work without their safety gear.

What it is

A camera, a phone and a speaker in a machined aluminium frame. It bolts to the wall beside a door and plugs into the mains.

What it does

Looks at everyone who walks up, checks they are wearing the gear that area needs, and says so out loud if something is missing.

SILENS, at the door“Safety glasses, please.”

06:52 · Grinding bay

Glasses on his head. Not on his eyes.

He has cut a thousand bars like this. Today the glasses went up for a second at the door and never came back down.

What SILENS is for

It catches this at the door.

Before he reaches the bench, the rig at the entrance sees bare eyes and says so, out loud, by name. One sentence. No write-up.

So the shift goes like this

Glasses down. Walk on.

He pulls them on without breaking stride. The screen turns green and stays quiet for the rest of the day.

Same bench · Same sparks

The sparks hit the lens. Not the eye.

That is the whole job. The right sentence, at the right door, every single time.

What it checks for

It checks for PPE.
Door by door.

Each entrance gets its own list, taken from the policy sign already on the wall. A grinding bay might need glasses and ear defenders. A mixing room adds the dust mask. SILENS checks the list for that door and nothing else.

How it answers

Cleared,
or corrected.

If everything is on, the screen turns green and it stays quiet. If something is missing, it names the item out loud while there is still time to go back for it. The screen shows an outline, never a face, and no picture is ever kept.

The rig's screen in green: Cleared. All set. Go ahead. Eye protection confirmed.
Cleared to work
The rig's screen in orange: PPE incomplete. Glasses, please.
PPE incomplete
The SILENS rig mounted on a concrete pillar at the entrance to a production floor, its screen checking a worker as a team in hard hats and hi-vis walks past.

What it sees

Every person.
Every entry.

It checks the moment someone walks up, not on a walk-round at the end of the shift. What they are wearing is confirmed. What is missing is named.

Why it matters

You can prove you
gave them the gear.
Can you prove
they wore it?

The law does not only ask whether you supplied safety equipment. It asks whether you made sure it was used. That duty is in the Safety, Health and Welfare at Work Act, in OSHA 1910.132, and in the PPE at Work Regulations. A signed policy and a sign on the wall show you meant well. Neither shows what happened at 06:40 on a Tuesday.

The numbers

This is what
skipping it costs.

2,000

US workers a day suffer a job-related eye injury that needs medical treatment.

NIOSH, via AOA
90%

of those eye injuries could be prevented or made less severe by the right eye protection.

American Optometric Association
680,000

workers in Great Britain were injured at work in 2024/25, by their own account.

13 of 43

work-related deaths in Ireland in 2023 involved working with vehicles.

What you get back

Something to show
the inspector.

Every check is recorded: the time, the area, what was missing, and how long it took to put right. Export it for your insurer, for an audit, or for the morning after an incident when somebody asks what you had in place at the door.

Who we are

Built in Ireland,
by someone who
works the floor.

SILENS is designed and supported from Ireland. It started on a production floor where eye protection is required at every door and checking it by hand is nobody's full-time job. When you write to us, the founder reads it.

Ernest Bruce-BrownFounder · AI engineer

Builds the detection software and the rig. Every demonstration request comes straight to him.

GDPR by design

No image, face or recording ever leaves the device. The screen shows an outline, not a person.

On-device checking

Detection runs entirely on the phone in the frame. One plug, no network, and 250 × 235 × 45 mm, light enough to carry in one hand.

Your policy, checked

Looks for the EN 166 eyewear your policy already requires, and confirms it is on at the door.

From Ireland

Designed and supported from Ireland, in EU working hours.
