Entry screening at a controlled site
Temperature measured as people pass, with an alert to a trained member of staff rather than an automatic refusal.
SafeACS Series
SafeACS Thermal Detection
Thermal screening with mask detection and liveness for safe access.
The problem
Where a site needs to screen people entering — a hospital, a food plant, a controlled facility — doing it with a handheld thermometer creates a queue, puts a member of staff at close range of everyone arriving, and produces no record. Thermal screening at the entry point removes the queue and the exposure. What it does not do is diagnose anything, and a screening programme built on the assumption that it does will fail in a way nobody notices until it matters.
Who this is for
- Healthcare and laboratory facilitiesEntry screening as one control among several, with a record
- Food, pharmaceutical and controlled productionA documented, consistent entry check that satisfies an auditor
- High-density workplacesScreening at shift change without creating the crowd it is meant to protect against
What people use it for
Combined with access control
One entry point handling identity and screening together, which is the only way it works at shift change.
Documented screening for audit
Where a regulator or a customer requires evidence that an entry control exists and is operated consistently.
What it needs to work
- Entry points, throughput at peak, and the indoor environment at the reader
- Your screening policy — the threshold, and what happens when it is exceeded
- Named, trained staff to handle a flagged case, because the device must not be the decision
- A lawful basis for processing what is health-related data in most jurisdictions
How it works
-
Measure at entry
Skin temperature measured as the person passes the reader, without contact and without stopping the flow.
-
Compare to threshold
Against the threshold in your policy, with the device calibrated to the environment it is installed in.
-
Alert a person
A flagged reading goes to trained staff for a secondary check. The device screens; the person decides.
-
Record the check
That screening occurred, and the outcome — with the reading itself retained only if your policy and legal basis require it.
How we deliver it
-
Policy first
The threshold, the secondary check, the outcome and the lawful basis. Without these the installation is equipment, not a control.
-
Site survey and siting
Ambient temperature, draughts, direct sun and distance all affect a reading, and the position is chosen for measurement rather than for convenience.
-
Install and calibrate
Calibrated in place, in its own environment, and re-checked on a defined schedule rather than once at handover.
-
Train and hand over
The staff who handle flagged cases trained on what the reading means and what it does not.
Where it runs
- Standalone at an entry point, or integrated with SafeACS access control
- Indoor, stable-environment mounting — outdoor and draughty positions degrade the measurement
- On-premises records, with retention set by your policy
Security and governance
- Temperature is health-related data in most jurisdictions — a lawful basis is required before deployment, not after
- A person makes every decision about an individual; the device never refuses entry on its own
- Retain the fact of screening rather than the reading, unless your policy requires otherwise
- Notice to everyone screened, and a defined route to question an outcome
Timeline
Installation is short. The policy and lawful-basis work should come first and typically takes longer, because it involves HR, legal and whoever owns the site's health and safety position — and a thermal installation without that behind it is difficult to defend if it is ever challenged.
What you receive
- Installed and calibrated units, with a documented re-calibration schedule
- A written screening procedure covering threshold, secondary check and outcome
- Records of screening consistent with your retention policy
- Training for the staff who handle flagged readings
- The datasheet for the units supplied, with their stated accuracy and conditions
What this does not do
This is the most important section on this page. Skin-temperature screening is not a medical device and does not diagnose anything. It cannot detect an infection in someone who has no fever, it cannot distinguish fever from a person who has just walked in from the heat or exercised, and its accuracy depends on ambient conditions, distance and calibration. It is a triage aid that directs a trained person to look more closely — nothing more. Any supplier who presents it as an infection control is misrepresenting the technology, and a screening programme that relies on it as a single barrier is not a screening programme.
Questions we are asked
Is this a medical device?
No. It is a screening aid. It measures skin temperature under specific conditions and flags a reading for a trained person to follow up. It does not diagnose, and it should never be described to staff or visitors as though it does.
Is thermal screening still worth deploying?
It depends entirely on why. Where a regulator, a customer or a site's own health policy requires a documented entry check, it does that job well and without a queue. As a general public-health measure its value is much narrower than it was widely presented to be, and we would rather discuss whether you need it than sell you one.
About the figures on this page
This page describes capability and method. It does not publish accuracy figures, throughput numbers or delivery dates, because those depend on your data, your systems and your scope — and a number published here would be wrong for most readers. You get them, in writing and against your own data, at scoping.
A first call is a technical conversation, not a pitch: what you have, what you need, and whether this is the right approach at all.
