Description
Another reason for the request may be to scan people without making them aware of the process. For that purpose, we have a hidden Walk Through Metal Detector. One person can pass through at a time.
The detector is fitted to the door frame, and it looks like it’s part of the furniture.
The alarm provider control unit and the buzzer mute system can be placed with the secretary, and the
person who is being protected can be behind the automatically locked door.
The secretary can either open the door if there is no danger or keep it locked if anything suspicious, and the detector provides an alarm.
Screening Without Announcing It
Most security screening is deliberately visible, because the deterrent is half the point. There are places where that logic reverses. A solicitor seeing a client about a hostile matter, a clinician in a benefits dispute, a housing officer delivering bad news: in those rooms an archway at the door changes the conversation before it starts, and tells the one person you are worried about exactly what you have in place.
This unit fits inside the door frame and reads as joinery. Nothing stands on the floor, nothing is walked through, and the visitor has no reason to think they were screened at all. The detection is conventional; the discretion is what you are buying.
The practical arrangement matters as much as the hardware. The control unit and buzzer mute sit with whoever is on reception, so they get the alarm silently while the person being protected waits behind an inner door that stays locked until reception releases it. That sequence, rather than the detector on its own, is what makes the setup useful.
Office Hidden Detector Questions, Answered
How much is the ThruScan Office Hidden detector?
£2,350. That is the same money as an entry level visible archway such as the ThruScan s3 at £2,250, so you are paying for discretion rather than for extra detection.
How is it hidden?
It fits into the door frame itself and reads as part of the joinery. There is no archway to walk through and nothing on the floor. People are screened without being told they are being screened, which is the entire point of it.
Where does the alarm go?
The control unit and the buzzer mute system sit with the receptionist or secretary rather than at the door. They see the alarm, the visitor does not, and the person being protected can stay behind an automatically locked inner door.
How does that work in practice?
A visitor arrives at the outer door. The frame screens them silently. If nothing shows, the secretary releases the inner door. If something does, the door stays locked and the situation is handled before anyone is in the room.
How many people can pass at once?
One at a time. It is a door frame rather than a wide portal, so it suits a controlled reception entrance rather than a queue. For volume screening you want a walk through archway.
What power does it need and what are the dimensions?
70 to 270 VAC at 50 to 60Hz, drawing 10W on standby and 20W when alarming. Net passage is 740 by 680 by 2,000mm, external 850 by 680 by 2,200mm. It operates from minus 20 to plus 70 degrees Celsius.
How heavy is it to install?
60kg net, 77kg gross, shipped in two boxes: 81 by 235 by 21cm at 65kg, and 25 by 80 by 27cm at 12kg. That is a two person installation into a prepared frame, not a drop in place job.
Who buys one?
Offices where someone needs protecting without announcing it: legal practices, clinics, executive suites, benefits and housing reception desks. Anywhere a visible archway would change the atmosphere or tell the wrong person what you are doing.
