01What the video shows
An office door fitted for touch-free access in both directions. On the way in, a Hikvision face recognition terminal recognises enrolled staff and releases the lock. On the way out, an infrared no-touch exit button, mounted on the wall beside the light switch, releases the door when a hand is waved in front of it.
Nobody has to touch a reader, a card or a button to get through the door, which is quicker for staff and more hygienic for everyone.
02How a no-touch exit button works
A standard exit button is a push switch. A no-touch exit button uses an infrared sensor instead: when a hand comes within a few centimetres, it sends the same 'open' signal to the access controller or lock power supply. The ring usually lights up to show it's ready and changes colour when triggered.
It is still an exit device, so it's installed alongside an emergency break-glass unit that releases the door even if the electronics fail. See exit buttons, break-glass and door sensors.
03Where touch-free access fits
Touch-free doors suit clinics and hospitals, labs, kitchens and food areas, busy office entrances and anywhere staff carry things in their hands. Face recognition handles the way in; the no-touch button handles the way out.
Compare credentials in fingerprint vs face recognition, and choose the lock with magnetic lock vs electric strike.
04Frequently asked questions
What is a no-touch exit button?
An exit button with an infrared sensor: you wave a hand in front of it instead of pressing it, and the door releases.
Can a no-touch button open the door by accident?
Its sensing range is short, typically a few centimetres, and it's mounted away from where people brush past, so accidental triggers are rare.
What if the power fails?
The door should always have an emergency break-glass release, and most magnetic locks release on power loss, so people can always get out.
