Room signs that fill your rooms, not your budget.
A sign at every door and a board in the lobby, from the calendars you already run. Free, starting soon or busy at a glance, bookable at the door, on a Raspberry Pi and a screen you choose.
Why good rooms sit empty.
Offices rarely lack rooms. They lack a way to see, from the corridor, which ones are free right now.
Nobody can see a calendar through a door
A free room looks taken from the corridor, so people walk past it and book one further away. A sign says free in a colour you can read from down the corridor.
Rooms get booked from a desk, not from where people are
When two people need a room now, they take the free one in front of them in two taps, and it is in the calendar before they sit down.
Meetings run into the next one
The sign turns to starting soon before the next booking and shows the time left, so the handover happens at the door and not ten minutes late.
Everything a room panel does.
Free or busy, from across the corridor
Each door gets a sign in your colours: free, starting soon or busy, with the time left and what comes next.
Book it at the door
On a touchscreen, people take a free room for 15 minutes to two hours, extend it or end it early. It lands in the room's own calendar.
One board for the whole floor
A lobby screen lists up to 24 rooms, free ones first, so nobody walks the corridor to find one.
- Your logo, your colours and your own words for free, soon and busy
- A timeline of the coming hours and a bar for the time left
- Seats per room, where your directory lists them
- A QR code on the sign that links wherever you want
- Microsoft 365, Google Workspace, CalDAV or a published iCal link
- The sign asks for the room's calendar every minute, without a reload
Priced like a screen, not like a panel.
A dedicated room panel is a device bought for one door and a licence paid for one room, every month. Panoptik is one subscription for every screen.
A dedicated room panel
- Hardware bought per door. Example: Evoko Naso, $1,800 list price in the US.¹
- A licence per room, every month. Example: Evoko Room License, $10 per room per month.¹
- Shows its room, and nothing else.
Panoptik
- A Raspberry Pi and a screen you choose. Touch only where people should book.
- One Pro plan for up to 15 signs and boards, not a licence per room:
For the whole workspace. VAT added at checkout where applicable
- The same screens run your other dashboards between meetings.
¹ Recommended list prices published by Biamp (licence) and US retailers (panel), checked on 21 October 2026, before tax and installation. Prices vary by region and reseller.
The lobby board does more than rooms.
A room sign is one of 25 widgets. The screen in the lobby can rotate between the room list, a welcome screen, departures from the nearest stop and your team's numbers, on a schedule you set. The kitchen screen and the wall in the ops room run on the same subscription.
Read what it needs, show what you allow.
Your app, your permissions
You connect your own Microsoft Entra app or Google service account, so your admin decides what can be read. A sign reads only mailboxes your directory lists as rooms.
Meeting titles stay private
Subjects and organisers are hidden until you turn them on, and a private meeting is never shown, only that the room is busy.
Hosted in the EU
Panoptik and its database run on servers in the EU, and the calendar connection is made from there, not from the screen.
Questions
Do the screens need to be touchscreens?
Only where people should book. A sign without touch still shows free, starting soon and busy, the time left and the rest of the day.
Which calendars work?
Microsoft 365, Google Workspace and CalDAV can be read and booked from the door. A published iCal link works too, read only.
What hardware do I need?
A Raspberry Pi running our image and a screen. You pair it with a six-digit code, and booking is switched on per sign. Any other screen can show a sign through a web link, without booking.
How many rooms fit on one board?
Up to 24, sorted with the free ones first or in the order you choose.
Which plan is it on?
Meeting rooms are on Pro, which covers up to 15 signs and boards. The 14-day trial includes it, no card needed. For more screens, Enterprise has no cap.
Try it on one door.
Start the 14-day trial, pair a Raspberry Pi at one meeting room and see whether people use it. No card needed.
